159-454: The Tall Building Awards or CTBUH Awards recognizes projects and individuals who have made an extraordinary contribution to the advancement of tall buildings and urban environment , as well as achieving sustainability at the highest and broadest level. The annual awards are judged by an independent panel of experts commissioned by the Council on Tall Buildings and Urban Habitat (CTBUH),
318-593: A Buttressed core . Trussed tube and X-bracing: China China , officially the People's Republic of China ( PRC ), is a country in East Asia . With a population exceeding 1.4 billion, it is the second-most populous country after India , representing 17.4% of the world population. China spans the equivalent of five time zones and borders fourteen countries by land . With an area of nearly 9.6 million square kilometers (3,700,000 sq mi), it
477-577: A failed war in northern Korea provoked widespread unrest. Under the succeeding Tang and Song dynasties , Chinese economy, technology, and culture entered a golden age. The Tang dynasty retained control of the Western Regions and the Silk Road, which brought traders to as far as Mesopotamia and the Horn of Africa , and made the capital Chang'an a cosmopolitan urban center. However, it
636-618: A non-profit organization headquartered in Chicago , Illinois . As of 2019, there are two individual lifetime achievement awards , The Lynn S. Beedle Lifetime Achievement Award and Fazlur Khan Lifetime Achievement Medal, and several categorical awards for projects and structures. In 2019 the CTBUH award categories were changed from buildings in specific regions to buildings based on height, region, function, innovation, construction, design, engineering, and safety. The most prestigious annual award,
795-541: A city consisting entirely of high-rise housing is the 16th-century city of Shibam in Yemen . Shibam was made up of over 500 tower houses, each one rising 5 to 11 stories high, with each floor being an apartment occupied by a single family. The city was built in this way in order to protect it from Bedouin attacks. Shibam still has the tallest mudbrick buildings in the world, with many of them over 30 m (98 ft) high. An early modern example of high-rise housing
954-401: A climate very suitable for agriculture and the country has been the world's largest producer of rice, wheat, tomatoes, eggplant, grapes, watermelon, spinach, and many other crops. In 2021, 12 percent of global permanent meadows and pastures belonged to China, as well as 8% of global cropland. China is one of 17 megadiverse countries , lying in two of the world's major biogeographic realms :
1113-532: A cultural identity among its populace still remembered in the ethnonym of the modern Han Chinese . The Han expanded the empire's territory considerably , with military campaigns reaching Central Asia, Mongolia , Korea , and Yunnan , and the recovery of Guangdong and northern Vietnam from Nanyue . Han involvement in Central Asia and Sogdia helped establish the land route of the Silk Road , replacing
1272-634: A disputed land border with India and Bhutan . China is additionally involved in maritime disputes with multiple countries over territory in the East and South China Seas , such as the Senkaku Islands and the entirety of South China Sea Islands . The People's Republic of China is a one-party state governed by the Chinese Communist Party (CCP). The CCP is officially guided by socialism with Chinese characteristics , which
1431-730: A far-reaching popular uprising (the May Fourth Movement ). In the late 1920s, the Kuomintang under Chiang Kai-shek was able to reunify the country under its own control with a series of deft military and political maneuverings known collectively as the Northern Expedition . The Kuomintang moved the nation's capital to Nanjing and implemented "political tutelage", an intermediate stage of political development outlined in Sun Yat-sen's Three Principles of
1590-475: A high density of plant species including numerous rare endemics. Tropical and seasonal rainforests , though confined to Yunnan and Hainan , contain a quarter of all the animal and plant species found in China. China has over 10,000 recorded species of fungi . In the early 2000s, China has suffered from environmental deterioration and pollution due to its rapid pace of industrialization. Regulations such as
1749-497: A major focus, special economic zones (SEZs) were created. Inefficient state-owned enterprises (SOEs) were restructured and some closed. This marked China's transition away from planned economy. China adopted its current constitution on 4 December 1982. In 1989, there were protests such those in Tiananmen Square , and then throughout the entire nation. Zhao Ziyang was put under house arrest for his sympathies to
SECTION 10
#17327656429221908-751: A more classical approach came back to global skyscraper design, that remains popular today. Examples are the Wells Fargo Center , NBC Tower , Parkview Square , 30 Park Place , the Messeturm , the iconic Petronas Towers and Jin Mao Tower . Other contemporary styles and movements in skyscraper design include organic , sustainable , neo-futurist , structuralist , high-tech , deconstructivist , blob , digital , streamline , novelty , critical regionalist , vernacular , Neo Art Deco and neohistorist , also known as revivalist . 3 September
2067-399: A particularly small surface area of what are conventionally thought of as walls. Because the walls are not load-bearing most skyscrapers are characterized by surface areas of windows made possible by the concept of steel frame and curtain wall. However, skyscrapers can also have curtain walls that mimic conventional walls and have a small surface area of windows. The concept of a skyscraper is
2226-404: A permanent navy which was supported by the developed shipbuilding industry along with the sea trade. Between the 10th and 11th century CE, the population of China doubled to around 100 million people, mostly because of the expansion of rice cultivation in central and southern China, and the production of abundant food surpluses. The Song dynasty also saw a revival of Confucianism , in response to
2385-420: A product of the industrialized age , made possible by cheap fossil fuel derived energy and industrially refined raw materials such as steel and concrete . The construction of skyscrapers was enabled by steel frame construction that surpassed brick and mortar construction starting at the end of the 19th century and finally surpassing it in the 20th century together with reinforced concrete construction as
2544-534: A profound impact, not only on the local or regional context, but on the genre of tall buildings globally. Which is innovative in planning, design and execution, the building must have influenced and re-shaped the field of tall building architecture, engineering, and urban planning. It is intended that the award will only be conferred on an occasional basis, when merited by an exceptional project perhaps every ten or fifteen years. Former CTBUH Awards Chair Gordon Gill, of Adrian Smith + Gordon Gill Architecture said: "There
2703-454: A proto-skyscraper, or to New York's seven-floor Equitable Life Building , built in 1870. Steel skeleton construction has allowed for today's supertall skyscrapers now being built worldwide. The nomination of one structure versus another being the first skyscraper, and why, depends on what factors are stressed. The structural definition of the word skyscraper was refined later by architectural historians, based on engineering developments of
2862-412: A proud and soaring thing, rising in sheer exaltation that from bottom to top it is a unit without a single dissenting line. Some structural engineers define a high-rise as any vertical construction for which wind is a more significant load factor than earthquake or weight. Note that this criterion fits not only high-rises but some other tall structures, such as towers . Different organizations from
3021-709: A significant contribution to a discipline for the design of tall buildings and the built urban environment. The award was first given in 2004 to Leslie E. Robertson , an American engineer and lead structural engineer of the Twin Towers of the original World Trade Center in New York City . Beginning in 2006 the CTBUH Awards began recognizing CTBUH Fellows for their contribution to the Council over an extended period of time, and in recognition of their work and
3180-571: A skyscraper today, it was record setting. The building of tall buildings in the 1880s gave the skyscraper its first architectural movement, broadly termed the Chicago School , which developed what has been called the Commercial Style. The architect, Major William Le Baron Jenney , created a load-bearing structural frame. In this building, a steel frame supported the entire weight of the walls, instead of load-bearing walls carrying
3339-417: A small surface area of windows. Modern skyscrapers often have a tubular structure , and are designed to act like a hollow cylinder to resist wind, seismic, and other lateral loads. To appear more slender, allow less wind exposure and transmit more daylight to the ground, many skyscrapers have a design with setbacks , which in some cases is also structurally required. As of September 2023 , fifteen cities in
SECTION 20
#17327656429223498-521: A time, the tallest of which is the 97.2 m (319 ft) high Asinelli Tower. A Florentine law of 1251 decreed that all urban buildings be immediately reduced to less than 26 m. Even medium-sized towns of the era are known to have proliferations of towers, such as the 72 towers that ranged up to 51 m height in San Gimignano . The medieval Egyptian city of Fustat housed many high-rise residential buildings, which Al-Muqaddasi in
3657-466: A variety of shapes, and it could be riveted, ensuring strong connections. The simplicity of a steel frame eliminated the inefficient part of a shear wall, the central portion, and consolidated support members in a much stronger fashion by allowing both horizontal and vertical supports throughout. Among steel's drawbacks is that as more material must be supported as height increases, the distance between supporting members must decrease, which in turn increases
3816-469: A vertical tube-like structural system capable of resisting lateral forces in any direction by cantilevering from the foundation". Closely spaced interconnected exterior columns form the tube. Horizontal loads (primarily wind) are supported by the structure as a whole. Framed tubes allow fewer interior columns, and so create more usable floor space, and about half the exterior surface is available for windows. Where larger openings like garage doors are required,
3975-457: Is Marxism adapted to Chinese circumstances . The Chinese constitution states that the PRC "is a socialist state governed by a people's democratic dictatorship that is led by the working class and based on an alliance of workers and peasants," that the state institutions "shall practice the principle of democratic centralism ," and that "the defining feature of socialism with Chinese characteristics
4134-664: Is "China" ( 中国 ; 中國 ; Zhōngguó ), from zhōng ('central') and guó ('state'), a term which developed under the Western Zhou dynasty in reference to its royal demesne . It was used in official documents as an synonym for the state under the Qing . The name Zhongguo is also translated as 'Middle Kingdom' in English. China is sometimes referred to as " mainland China " or "the Mainland" when distinguishing it from
4293-856: Is bounded by the Bohai , Yellow , East China and South China seas. China connects through the Kazakh border to the Eurasian Steppe . The territory of China lies between latitudes 18° and 54° N , and longitudes 73° and 135° E . The geographical center of China is marked by the Center of the Country Monument at 35°50′40.9″N 103°27′7.5″E / 35.844694°N 103.452083°E / 35.844694; 103.452083 ( Geographical center of China ) . China's landscapes vary significantly across its vast territory. In
4452-585: Is commonly agreed that pre-modern China's population experienced two growth spurts, one during the Northern Song period (960–1127), and other during the Qing period (around 1700–1830). By the High Qing era China was possibly the most commercialized country in the world, and imperial China experienced a second commercial revolution by the end of the 18th century. On the other hand, the centralized autocracy
4611-704: Is having a steel frame that supports curtain walls . This idea was invented by Viollet le Duc in his discourses on architecture. These curtain walls either bear on the framework below or are suspended from the framework above, rather than resting on load-bearing walls of conventional construction. Some early skyscrapers have a steel frame that enables the construction of load-bearing walls taller than of those made of reinforced concrete . Modern skyscraper walls are not load-bearing , and most skyscrapers are characterized by large surface areas of windows made possible by steel frames and curtain walls. However, skyscrapers can have curtain walls that mimic conventional walls with
4770-461: Is home to a variety of forest types. Cold coniferous forests predominate in the north of the country, supporting animal species such as moose and Asian black bear , along with over 120 bird species. The understory of moist conifer forests may contain thickets of bamboo . In higher montane stands of juniper and yew , the bamboo is replaced by rhododendrons . Subtropical forests, which are predominate in central and southern China, support
4929-406: Is important in most building design, but particularly for skyscrapers since even a small chance of catastrophic failure is unacceptable given the tremendous damage such failure would cause. This presents a paradox to civil engineers : the only way to assure a lack of failure is to test for all modes of failure, in both the laboratory and the real world. But the only way to know of all modes of failure

5088-433: Is largely from the force of the building material itself. In most building designs, the weight of the structure is much larger than the weight of the material that it will support beyond its own weight. In technical terms, the dead load , the load of the structure, is larger than the live load , the weight of things in the structure (people, furniture, vehicles, etc.). As such, the amount of structural material required within
5247-451: Is protected by law, and as of 2005 , the country has over 2,349 nature reserves , covering a total area of 149.95 million hectares, 15 percent of China's total land area. Most wild animals have been eliminated from the core agricultural regions of east and central China, but they have fared better in the mountainous south and west. The Baiji was confirmed extinct on 12 December 2006. China has over 32,000 species of vascular plants, and

The country is divided into 33 province-level divisions : 22 provinces , five autonomous regions , four municipalities , and two semi-autonomous special administrative regions . Beijing is the country's capital, while Shanghai is its most populous city by urban area and largest financial center . China is considered one of the cradles of civilization :
5565-451: Is the direct ancestor of modern Chinese characters . The Shang were overthrown by the Zhou , who ruled between the 11th and 5th centuries BCE, though the centralized authority of Son of Heaven was slowly eroded by fengjian lords. Some principalities eventually emerged from the weakened Zhou and continually waged war with each other during the 300-year Spring and Autumn period . By
5724-399: Is the global commemorative day for skyscrapers, called "Skyscraper Day". New York City developers competed among themselves, with successively taller buildings claiming the title of "world's tallest" in the 1920s and early 1930s, culminating with the completion of the 318.9 m (1,046 ft) Chrysler Building in 1930 and the 443.2 m (1,454 ft) Empire State Building in 1931,
5883-401: Is the leadership of the Chinese Communist Party." The PRC officially terms itself as a democracy , using terms such as "socialist consultative democracy", and " whole-process people's democracy ". However, the country is commonly described as an authoritarian one-party state and a dictatorship , with among the heaviest restrictions worldwide in many areas, most notably against freedom of
6042-559: Is the world's leading investor in renewable energy and its commercialization , with $ 546 billion invested in 2022; it is a major manufacturer of renewable energy technologies and invests heavily in local-scale renewable energy projects. Long heavily relying on non-renewable energy sources such as coal, China's adaptation of renewable energy has increased significantly in recent years, with their share increasing from 26.3 percent in 2016 to 31.9 percent in 2022. In 2023, 60.5% of China's electricity came from coal (largest producer in
6201-419: Is to learn from previous failures. Thus, no engineer can be absolutely sure that a given structure will resist all loadings that could cause failure; instead, one can only have large enough margins of safety such that a failure is acceptably unlikely. When buildings do fail, engineers question whether the failure was due to some lack of foresight or due to some unknowable factor. The load a skyscraper experiences

It is a founding member of several multilateral and regional organizations such as the AIIB , the Silk Road Fund , the New Development Bank , and
8427-505: The Turpan Depression . China's climate is mainly dominated by dry seasons and wet monsoons , which lead to pronounced temperature differences between winter and summer. In the winter, northern winds coming from high-latitude areas are cold and dry; in summer, southern winds from coastal areas at lower latitudes are warm and moist. A major environmental issue in China is the continued expansion of its deserts , particularly
8586-621: The World Trade Organization in 2001. At the 16th CCP National Congress in 2002, Hu Jintao succeeded Jiang as the general secretary. Under Hu, China maintained its high rate of economic growth, overtaking the United Kingdom, France, Germany and Japan to become the world's second-largest economy. However, the growth also severely impacted the country's resources and environment, and caused major social displacement. Xi Jinping succeeded Hu as paramount leader at

In 2020, the Chinese government announced its aims for the country to reach its peak emissions levels before 2030, and achieve carbon neutrality by 2060 in line with the Paris Agreement , which, according to Climate Action Tracker , would lower the expected rise in global temperature by 0.2–0.3 degrees – "the biggest single reduction ever estimated by the Climate Action Tracker". China
10812-807: The 26th century BC. It was not surpassed in height for thousands of years, the 160 m (520 ft) Lincoln Cathedral having exceeded it in 1311–1549, before its central spire collapsed. The latter in turn was not surpassed until the 555-foot (169 m) Washington Monument in 1884. However, being uninhabited, none of these structures actually comply with the modern definition of a skyscraper. High-rise apartments flourished in classical antiquity . Ancient Roman insulae in imperial cities reached 10 and more stories. Beginning with Augustus (r. 30 BC-14 AD), several emperors attempted to establish limits of 20–25 m for multi-stories buildings, but were met with only limited success. Lower floors were typically occupied by shops or wealthy families, with

11607-449: The CCP. The NPC is dominated by the CCP, with another eight minor parties having nominal representation under the condition of upholding CCP leadership. The president is elected by the NPC. The presidency is the ceremonial state representative, but not the constitutional head of state. The incumbent president is Xi Jinping, who is also the general secretary of the CCP and the chairman of
11766-566: The CTBUH, is the distance between the highest floor and its architectural top (excluding antennae, flagpole or other functional extensions). Vanity height first appeared in New York City skyscrapers as early as the 1920s and 1930s but supertall buildings have relied on such uninhabitable extensions for on average 30% of their height, raising potential definitional and sustainability issues. The current era of skyscrapers focuses on sustainability , its built and natural environments, including
11925-638: The Central Military Commission , making him China's paramount leader and supreme commander of the Armed Forces. The premier is the head of government , with Li Qiang being the incumbent. The premier is officially nominated by the president and then elected by the NPC, and has generally been either the second- or third-ranking member of the Politburo Standing Committee (PSC). The premier presides over
12084-450: The Gobi Desert. Although barrier tree lines planted since the 1970s have reduced the frequency of sandstorms , prolonged drought and poor agricultural practices have resulted in dust storms plaguing northern China each spring, which then spread to other parts of East Asia, including Japan and Korea. Water quality, erosion , and pollution control have become important issues in China's relations with other countries. Melting glaciers in
12243-717: The Himalayas could potentially lead to water shortages for hundreds of millions of people. According to academics, in order to limit climate change in China to 1.5 °C (2.7 °F) electricity generation from coal in China without carbon capture must be phased out by 2045. With current policies, the GHG emissions of China will probably peak in 2025, and by 2030 they will return to 2022 levels. However, such pathway still leads to three-degree temperature rise. Official government statistics about Chinese agricultural productivity are considered unreliable, due to exaggeration of production at subsidiary government levels. Much of China has
12402-705: The Kuomintang and the CCP. Japanese forces committed numerous war atrocities against the civilian population; as many as 20 million Chinese civilians died. An estimated 40,000 to 300,000 Chinese were massacred in Nanjing alone during the Japanese occupation. China, along with the UK, the United States, and the Soviet Union , were recognized as the Allied " Big Four " in the Declaration by United Nations . Along with
12561-648: The PRC initially allied closely with the Soviet Union , the relations between the two communist nations gradually deteriorated , leading China to develop an independent industrial system and its own nuclear weapons . The Chinese population increased from 550 million in 1950 to 900 million in 1974. However, the Great Leap Forward , an idealistic massive industrialization project, resulted in an estimated 15 to 55 million deaths between 1959 and 1961, mostly from starvation. In 1964, China detonated its first atomic bomb. In 1966, Mao and his allies launched
12720-949: The People program for transforming China into a modern democratic state. The Kuomintang briefly allied with the Chinese Communist Party (CCP) during the Northern Expedition, though the alliance broke down in 1927 after Chiang violently suppressed the CCP and other leftists in Shanghai, marking the beginning of the Chinese Civil War . The CCP declared areas of the country as the Chinese Soviet Republic (Jiangxi Soviet) in November 1931 in Ruijin , Jiangxi . The Jiangxi Soviet
12879-535: The People's Republic of China in Tiananmen Square , Beijing . In 1950, the PRC captured Hainan from the ROC and annexed Tibet . However, remaining Kuomintang forces continued to wage an insurgency in western China throughout the 1950s. The CCP consolidated its popularity among the peasants through the Land Reform Movement , which included the state-tolerated executions of between 1 and 2 million landlords by peasants and former tenants. Though
13038-573: The Portuguese explorer Duarte Barbosa . Barbosa's usage was derived from Persian Chīn ( چین ), which in turn derived from Sanskrit Cīna ( चीन ). Cīna was first used in early Hindu scripture, including the Mahabharata (5th century BCE) and the Laws of Manu (2nd century BCE). In 1655, Martino Martini suggested that the word China is derived ultimately from
13197-488: The United States (16.1), Australia (16.8) and South Korea (13.6). Greenhouse gas emissions by China are the world's largest . The country has significant water pollution problems; only 89.4% of China's national surface water was graded suitable for human consumption by the Ministry of Ecology and Environment in 2023. China has prioritized clamping down on pollution, bringing a significant decrease in air pollution in
13356-407: The United States and Europe define skyscrapers as buildings at least 150 m (490 ft) in height or taller, with " supertall " skyscrapers for buildings higher than 300 m (984 ft) and " megatall " skyscrapers for those taller than 600 m (1,969 ft). The tallest structure in ancient times was the 146 m (479 ft) Great Pyramid of Giza in ancient Egypt , built in
13515-556: The Xia is the earliest for which there are both contemporary written records and undisputed archaeological evidence. The Shang ruled much of the Yellow River valley until the 11th century BCE, with the earliest hard evidence dated c. 1300 BCE . The oracle bone script , attested from c. 1250 BCE but generally assumed to be considerably older, represents the oldest known form of written Chinese , and
13674-513: The Xia's historicity came under increasing scrutiny, in part due to the earliest known attestation of the Xia being written millennia after the date given for their collapse. In 1958, archaeologists discovered sites belonging to the Erlitou culture that existed during the early Bronze Age ; they have since been characterized as the remains of the historical Xia, but this conception is often rejected. The Shang dynasty that traditionally succeeded
13833-681: The Yuan in 1368 and founded the Ming dynasty as the Hongwu Emperor . Under the Ming dynasty, China enjoyed another golden age, developing one of the strongest navies in the world and a rich and prosperous economy amid a flourishing of art and culture. It was during this period that admiral Zheng He led the Ming treasure voyages throughout the Indian Ocean, reaching as far as East Africa. In
13992-590: The advancement of tall buildings and the urban environment during his or her professional career. The 2002 award was given and named after Lynn S. Beedle , an American structural engineer and founder of the Council on Tall Buildings And Urban Habitat. In 2004 a second lifetime award was created, the Fazlur R. Kahn Lifetime Award, named after Bangladeshi-American structural engineer and architect Fazlur Rahman Khan , which recognizes an individual for demonstrated excellence in technical design and/or research that has made
14151-546: The advancement of tall buildings and the urban environment, and that achieve sustainability and wellness at the highest and broadest level. The Beetham Tower , completed in 2006 in Manchester , England was the first recipient of the award. The second award added in 2007 was the Best Sustainable Building Award , which was awarded to Hearst Tower , completed in 2006 in New York City. In 2008,
14310-497: The amount of material that must be supported. This becomes inefficient and uneconomic for buildings above 40 stories tall as usable floor spaces are reduced for supporting column and due to more usage of steel. A new structural system of framed tubes was developed by Fazlur Rahman Khan in 1963. The framed tube structure is defined as "a three dimensional space structure composed of three, four, or possibly more frames, braced frames, or shear walls, joined at or near their edges to form
14469-820: The bulk of East Asia, bordering Vietnam , Laos , and Myanmar in Southeast Asia; India , Bhutan , Nepal , Pakistan and Afghanistan in South Asia; Tajikistan , Kyrgyzstan and Kazakhstan in Central Asia; and Russia, Mongolia , and North Korea in Inner Asia and Northeast Asia . It is narrowly separated from Bangladesh and Thailand to the southwest and south, and has several maritime neighbors such as Japan , Philippines , Malaysia , and Indonesia . China has resolved its land borders with 12 out of 14 neighboring countries, having pursued substantial compromises in most of them. China currently has
14628-424: The classical designs of the early skyscrapers , instead embracing the uniform international style ; many older skyscrapers were redesigned to suit contemporary tastes or even demolished—such as New York's Singer Building , once the world's tallest skyscraper. German -American architect Ludwig Mies van der Rohe became one of the world's most renowned architects in the second half of the 20th century. He conceived
14787-462: The country in the late 19th century to various European powers by a series of unequal treaties . After decades of Qing China on the decline, the 1911 Revolution overthrew the Qing dynasty and the monarchy and the Republic of China (ROC) was established the following year. The country under the nascent Beiyang government was unstable and ultimately fragmented during the Warlord Era , which
14946-648: The creation of a significant number of early skyscrapers, though none of these were steel reinforced and few remain today. Height limits and fire restrictions were later introduced. In the late 1800s, London builders found building heights limited due to issues with existing buildings. High-rise development in London is restricted at certain sites if it would obstruct protected views of St Paul's Cathedral and other historic buildings. This policy, 'St Paul's Heights', has officially been in operation since 1927. Concerns about aesthetics and fire safety had likewise hampered
15105-756: The development of skyscrapers across continental Europe for the first half of the 20th century. By 1940, there were around 100 high-rise buildings in Europe ( List of early skyscrapers ). Some examples of these are the 43 m (141 ft) tall 1898 Witte Huis (White House) in Rotterdam ; the 51.5 m (169 ft) tall PAST Building (1906–1908) in Warsaw ; the Royal Liver Building in Liverpool, completed in 1911 and 90 m (300 ft) high;
15264-610: The earlier path over the Himalayas to India. Han China gradually became the largest economy of the ancient world. Despite the Han's initial decentralization and the official abandonment of the Qin philosophy of Legalism in favor of Confucianism , Qin's legalist institutions and policies continued to be employed by the Han government and its successors. After the end of the Han dynasty , a period of strife known as Three Kingdoms followed, at
15423-402: The early 1960s Bangladeshi-American structural engineer Fazlur Rahman Khan , considered the "father of tubular designs " for high-rises, discovered that the dominating rigid steel frame structure was not the only system apt for tall buildings, marking a new era of skyscraper construction in terms of multiple structural systems . His central innovation in skyscraper design and construction
15582-537: The early Ming dynasty, China's capital was moved from Nanjing to Beijing. With the budding of capitalism, philosophers such as Wang Yangming critiqued and expanded Neo-Confucianism with concepts of individualism and equality of four occupations . The scholar-official stratum became a supporting force of industry and commerce in the tax boycott movements, which, together with the famines and defense against Japanese invasions of Korea (1592–1598) and Later Jin incursions led to an exhausted treasury. In 1644, Beijing
15741-737: The east, along the shores of the Yellow Sea and the East China Sea, there are extensive and densely populated alluvial plains , while on the edges of the Inner Mongolian plateau in the north, broad grasslands predominate. Southern China is dominated by hills and low mountain ranges, while the central-east hosts the deltas of China's two major rivers, the Yellow River and the Yangtze River. Other major rivers include
15900-656: The end of which Wei was swiftly overthrown by the Jin dynasty . The Jin fell to civil war upon the ascension of a developmentally disabled emperor ; the Five Barbarians then rebelled and ruled northern China as the Sixteen States . The Xianbei unified them as the Northern Wei , whose Emperor Xiaowen reversed his predecessors' apartheid policies and enforced a drastic sinification on his subjects . In
16059-416: The environment and loaded structures with decorative elements and extravagant finishes. This approach to design was opposed by Fazlur Khan and he considered the designs to be whimsical rather than rational. Moreover, he considered the work to be a waste of precious natural resources. Khan's work promoted structures integrated with architecture and the least use of material resulting in the smallest impact on
16218-454: The environment. The next era of skyscrapers will focus on the environment including performance of structures, types of material, construction practices, absolute minimal use of materials/natural resources, embodied energy within the structures, and more importantly, a holistically integrated building systems approach. Modern building practices regarding supertall structures have led to the study of "vanity height". Vanity height, according to
16377-473: The face of popular condemnation and opposition from his own Beiyang Army , he was forced to abdicate and re-establish the republic in 1916. After Yuan Shikai's death in 1916, China was politically fragmented. Its Beijing-based government was internationally recognized but virtually powerless; regional warlords controlled most of its territory. During this period , China participated in World War I and saw
16536-555: The failed Taiping Rebellion that ravaged southern China in the 1850s and 1860s and the Dungan Revolt (1862–1877) in the northwest. The initial success of the Self-Strengthening Movement of the 1860s was frustrated by a series of military defeats in the 1880s and 1890s. In the 19th century, the great Chinese diaspora began. Losses due to emigration were added to by conflicts and catastrophes such as
16695-528: The first building in the world to feature a metal-framed glass curtain wall , a design element which creates light, airy interiors and has since been used the world over as a defining feature of skyscrapers". Further developments led to what many individuals and organizations consider the world's first skyscraper, the ten-story Home Insurance Building in Chicago, built in 1884–1885. While its original height of 42.1 m (138 ft) does not even qualify as
16854-475: The first human inhabitants in the region arrived during the Paleolithic . By the late 2nd millennium BCE, the earliest dynastic states had emerged in the Yellow River basin. The 8th–3rd centuries BCE saw a breakdown in the authority of the Zhou dynasty , accompanied by the emergence of administrative and military techniques, literature , philosophy , and historiography . In 221 BCE, China
17013-560: The following award criteria for skyscrapers. The criteria for the Innovation Award: The criteria for the 10 Year Award: The Council on Tall Buildings and Urban Habitat bestowed a new award for Burj Khalifa at its annual "Best Tall Buildings Awards Ceremony" on 25 October 2010 when Burj Khalifa honored as first recipient of CTBUH's new Tall Building "Global Icon" Award. According to CTBUH the new "Global Icon" award recognizes those very special supertall skyscrapers that make
17172-479: The glass façade skyscraper and, along with Norwegian Fred Severud , designed the Seagram Building in 1958, a skyscraper that is often regarded as the pinnacle of modernist high-rise architecture. Skyscraper construction surged throughout the 1960s. The impetus behind the upswing was a series of transformative innovations which made it possible for people to live and work in "cities in the sky". In
17331-612: The growth of Buddhism during the Tang, and a flourishing of philosophy and the arts, as landscape art and porcelain were brought to new levels of complexity. However, the military weakness of the Song army was observed by the Jin dynasty . In 1127, Emperor Huizong of Song and the capital Bianjing were captured during the Jin–Song wars . The remnants of the Song retreated to southern China . The Mongol conquest of China began in 1205 with
17490-473: The hundred-story John Hancock Center and the massive 442 m (1,450 ft) Willis Tower . Other pioneers of this field include Hal Iyengar , William LeMessurier , and Minoru Yamasaki , the architect of the World Trade Center . Many buildings designed in the 70s lacked a particular style and recalled ornamentation from earlier buildings designed before the 50s. These design plans ignored
17649-400: The informal paramount leader . The current general secretary is Xi Jinping , who took office on 15 November 2012. At the local level, the secretary of the CCP committee of a subdivision outranks the local government level; CCP committee secretary of a provincial division outranks the governor while the CCP committee secretary of a city outranks the mayor. The government in China is under
17808-409: The largest importer of Russian crude oil in 2022. China is the third-largest country in the world by land area after Russia , and the third- or fourth-largest country in the world by total area. China's total area is generally stated as being approximately 9,600,000 km (3,700,000 sq mi). Specific area figures range from 9,572,900 km (3,696,100 sq mi) according to
17967-454: The lower levels of a skyscraper will be much larger than the material required within higher levels. This is not always visually apparent. The Empire State Building 's setbacks are actually a result of the building code at the time ( 1916 Zoning Resolution ), and were not structurally required. On the other hand, John Hancock Center 's shape is uniquely the result of how it supports loads. Vertical supports can come in several types, among which
18126-674: The most common for skyscrapers can be categorized as steel frames, concrete cores, tube within tube design, and shear walls. The wind loading on a skyscraper is also considerable. In fact, the lateral wind load imposed on supertall structures is generally the governing factor in the structural design. Wind pressure increases with height, so for very tall buildings, the loads associated with wind are larger than dead or live loads. Other vertical and horizontal loading factors come from varied, unpredictable sources, such as earthquakes. By 1895, steel had replaced cast iron as skyscrapers' structural material. Its malleability allowed it to be formed into
18285-435: The most complex encountered given the balances required between economics , engineering , and construction management. One common feature of skyscrapers is a steel framework from which curtain walls are suspended, rather than load-bearing walls of conventional construction. Most skyscrapers have a steel frame that enables them to be built taller than typical load-bearing walls of reinforced concrete. Skyscrapers usually have
18444-715: The multiple consultation mechanisms that exist in Chinese government. According to the CCP constitution , its highest body is the National Congress held every five years. The National Congress elects the Central Committee , who then elects the party's Politburo , Politburo Standing Committee and the general secretary ( party leader ), the top leadership of the country. The general secretary holds ultimate power and authority over party and state and serves as
18603-720: The name of the Qin dynasty (221–206 BCE). Although use in Indian sources precedes this dynasty, this derivation is still given in various sources. The origin of the Sanskrit word is a matter of debate. Alternative suggestions include the names for Yelang and the Jing or Chu state. The official name of the modern state is the "People's Republic of China" ( simplified Chinese : 中华人民共和国 ; traditional Chinese : 中華人民共和國 ; pinyin : Zhōnghuá rénmín gònghéguó ). The shorter form
18762-472: The other three great powers, China was one of the four major Allies of World War II , and was later considered one of the primary victors in the war. After the surrender of Japan in 1945, Taiwan, including the Penghu , was handed over to Chinese control ; however, the validity of this handover is controversial. China emerged victorious but war-ravaged and financially drained. The continued distrust between
18921-406: The performance of structures, types of materials, construction practices, absolute minimal use of materials and natural resources, energy within the structure, and a holistically integrated building systems approach. LEED is a current green building standard. Architecturally, with the movements of Postmodernism , New Urbanism and New Classical Architecture , that established since the 1980s,
19080-553: The press , freedom of assembly , free formation of social organizations , freedom of religion and free access to the Internet . China has consistently been ranked amongst the lowest as an "authoritarian regime" by the Economist Intelligence Unit 's Democracy Index , ranking at 148th out of 167 countries in 2023. Other sources suggest that terming China as "authoritarian" does not sufficiently account for
19239-728: The price of steel decreased and labor costs increased. The steel frames become inefficient and uneconomic for supertall buildings as usable floor space is reduced for progressively larger supporting columns. Since about 1960, tubular designs have been used for high rises. This reduces the usage of material (more efficient in economic terms – Willis Tower uses a third less steel than the Empire State Building) yet allows greater height. It allows fewer interior columns, and so creates more usable floor space. It further enables buildings to take on various shapes. Elevators are characteristic to skyscrapers. In 1852 Elisha Otis introduced
19398-417: The protests and was replaced by Jiang Zemin . Jiang continued economic reforms, closing many SOEs and trimming down " iron rice bowl " (life-tenure positions). China's economy grew sevenfold during this time. British Hong Kong and Portuguese Macau returned to China in 1997 and 1999 , respectively, as special administrative regions under the principle of one country, two systems . The country joined
19557-484: The safety elevator at the E. V. Haughwout Building in New York City, allowing convenient and safe transport to buildings' upper floors. Otis later introduced the first commercial passenger elevators to the Equitable Life Building in 1870, considered by some architectural historians to be the first skyscraper. Another crucial development was the use of a steel frame instead of stone or brick, otherwise
19716-643: The safety elevator, allowing convenient and safe passenger movement to upper floors. Another crucial development was the use of a steel frame instead of stone or brick, otherwise the walls on the lower floors on a tall building would be too thick to be practical. Today major manufacturers of elevators include Otis , ThyssenKrupp , Schindler , and KONE . Advances in construction techniques have allowed skyscrapers to narrow in width, while increasing in height. Some of these new techniques include mass dampers to reduce vibrations and swaying, and gaps to allow air to pass through, reducing wind shear. Good structural design
19875-918: The second year of CTBUH Awards for structures, the Council on Tall Buildings and Urban Habitat added four geographical categories for the best tall building, the regions were Americas (North and South), Asia & Australasia , Europe , and Middle East & Africa . The Best Tall Building Award was then awarded to one of the regional award winners. In 2008 the CTBUH Best Tall Building Award winners were New York Times Building in New York City; Shanghai World Financial Center in Shanghai , China ; 51 Lime Street in London, England; and Bahrain World Trade Center in Manama , Bahrain . The Best Tall Building Award Winner Worldwide
20034-461: The sharing of their knowledge in the design and construction of tall buildings and the urban habitat. The first CTBUH Fellows in 2006 were A. Eugene Kohn , Charles A. DeBenedittis, Gilberto do Valle, and Henry Jack Cowan. The Council on Tall Buildings and Urban Habitat added two categories starting in 2007 which recognize completed structures for excellence. The Best Tall Building Award recognizes projects that have made extraordinary contributions to
20193-637: The sole control of the CCP. The CCP controls appointments in government bodies, with most senior government officials being CCP members. The National People's Congress (NPC), with nearly 3,000-members, is constitutionally the " highest organ of state power ", though it has been also described as a " rubber stamp " body. The NPC meets annually, while the NPC Standing Committee , around 150 members elected from NPC delegates, meets every couple of months. Elections are indirect and not pluralistic, with nominations at all levels being controlled by
20352-761: The south, the general Liu Yu secured the abdication of the Jin in favor of the Liu Song . The various successors of these states became known as the Northern and Southern dynasties , with the two areas finally reunited by the Sui in 581. The Sui restored the Han to power through China, reformed its agriculture, economy and imperial examination system, constructed the Grand Canal , and patronized Buddhism . However, they fell quickly when their conscription for public works and
20511-657: The standardization of Chinese characters, measurements , road widths, and currency . His dynasty also conquered the Yue tribes in Guangxi , Guangdong , and Northern Vietnam . The Qin dynasty lasted only fifteen years, falling soon after the First Emperor's death. Following widespread revolts during which the imperial library was burned , the Han dynasty emerged to rule China between 206 BCE and 220 CE, creating
20670-576: The time of the Warring States period of the 5th–3rd centuries BCE, there were seven major powerful states left. The Warring States period ended in 221 BCE after the state of Qin conquered the other six states, reunited China and established the dominant order of autocracy . King Zheng of Qin proclaimed himself the Emperor of the Qin dynasty , becoming the first emperor of a unified China. He enacted Qin's legalist reforms, notably
20829-438: The title for six years. The design and construction of skyscrapers involves creating safe, habitable spaces in very tall buildings. The buildings must support their weight, resist wind and earthquakes, and protect occupants from fire. Yet they must also be conveniently accessible, even on the upper floors, and provide utilities and a comfortable climate for the occupants. The problems posed in skyscraper design are considered among
20988-501: The tube frame must be interrupted, with transfer girders used to maintain structural integrity. Tube structures cut down costs, at the same time allowing buildings to reach greater heights. Concrete tube-frame construction was first used in the DeWitt-Chestnut Apartment Building , completed in Chicago in 1963, and soon after in the John Hancock Center and World Trade Center . The tubular systems are fundamental to tall building design. Most buildings over 40 stories constructed since
21147-416: The tube structure was the Chestnut De-Witt apartment building, considered to be a major development in modern architecture. These new designs opened an economic door for contractors, engineers, architects, and investors, providing vast amounts of real estate space on minimal plots of land. Over the next fifteen years, many towers were built by Fazlur Rahman Khan and the " Second Chicago School ", including
21306-419: The upper rented to the lower classes. Surviving Oxyrhynchus Papyri indicate that seven-stories buildings existed in provincial towns such as in 3rd century AD Hermopolis in Roman Egypt . The skylines of many important medieval cities had large numbers of high-rise urban towers, built by the wealthy for defense and status. The residential Towers of 12th century Bologna numbered between 80 and 100 at
21465-409: The walls on the lower floors on a tall building would be too thick to be practical. An early development in this area was Oriel Chambers in Liverpool , England, built in 1864. It was only five floors high. The Royal Academy of Arts states, "critics at the time were horrified by its 'large agglomerations of protruding plate glass bubbles'. In fact, it was a precursor to Modernist architecture, being
21624-493: The weight of the building. This development led to the "Chicago skeleton" form of construction. In addition to the steel frame, the Home Insurance Building also utilized fireproofing, elevators, and electrical wiring, key elements in most skyscrapers today. Burnham and Root 's 45 m (148 ft) Rand McNally Building in Chicago, 1889, was the first all-steel framed skyscraper, while Louis Sullivan 's 41 m (135 ft) Wainwright Building in St. Louis, Missouri, 1891,
21783-554: The winners of its annual "Best Tall Building" awards for 2011 on June 15, 2011. Pontificia Universidad Javeriana Skyscraper A skyscraper is a tall continuously habitable building having multiple floors. Modern sources define skyscrapers as being at least 100 meters (330 ft) or 150 meters (490 ft) in height, though there is no universally accepted definition, other than being very tall high-rise buildings . Skyscrapers may host offices, hotels, residential spaces, and retail spaces. One common feature of skyscrapers
21942-814: The world have more than 100 skyscrapers that are 150 m (492 ft) or taller: Hong Kong with 552 skyscrapers; Shenzhen , China with 373 skyscrapers; New York City , US with 314 skyscrapers; Dubai , UAE with 252 skyscrapers; Guangzhou , China with 188 skyscrapers; Shanghai , China with 183 skyscrapers; Tokyo , Japan with 168 skyscrapers; Kuala Lumpur , Malaysia with 156 skyscrapers; Wuhan , China with 149 skyscrapers; Chongqing , China, with 144 skyscrapers; Chicago , US, with 137 skyscrapers; Chengdu , China with 117 skyscrapers; Jakarta , Indonesia , with 112 skyscrapers; Bangkok , Thailand , with 111 skyscrapers, and Mumbai , India with 102. As of 2024, there are over 7 thousand skyscrapers over 150 m (492 ft) in height worldwide. The term "skyscraper"
22101-490: The world's tallest building for forty years. The first completed 417 m (1,368 ft) tall World Trade Center tower became the world's tallest building in 1972. However, it was overtaken by the Sears Tower (now Willis Tower ) in Chicago within two years. The 442 m (1,450 ft) tall Sears Tower stood as the world's tallest building for 24 years, from 1974 until 1998, until it was edged out by 452 m (1,483 ft) Petronas Twin Towers in Kuala Lumpur, which held
22260-432: The world's tallest building, New York took the lead by 1895 with the completion of the 103 m (338 ft) tall American Surety Building , leaving New York with the title of the world's tallest building for many years. Modern skyscrapers are built with steel or reinforced concrete frameworks and curtain walls of glass or polished stone . They use mechanical equipment such as water pumps and elevators . Since
22419-485: The world), 1,221 species of birds (eighth), 424 species of reptiles (seventh) and 333 species of amphibians (seventh). Wildlife in China shares habitat with, and bears acute pressure from, one of the world's largest population of humans. At least 840 animal species are threatened, vulnerable or in danger of local extinction , due mainly to human activity such as habitat destruction, pollution and poaching for food, fur and traditional Chinese medicine . Endangered wildlife
22578-428: The world), 13.2% from hydroelectric power (largest), 9.4% from wind (largest), 6.2% from solar energy (largest), 4.6% from nuclear energy (second-largest), 3.3% from natural gas (fifth-largest), and 2.2% from bioenergy (largest); in total, 31% of China's energy came from renewable energy sources. Despite its emphasis on renewables, China remains deeply connected to global oil markets and next to India, has been
22737-418: The world, although only partially iron framed, is The Flaxmill in Shrewsbury , England. Built in 1797, it is seen as the "grandfather of skyscrapers", since its fireproof combination of cast iron columns and cast iron beams developed into the modern steel frame that made modern skyscrapers possible. In 2013 funding was confirmed to convert the derelict building into offices. In 1857, Elisha Otis introduced

24009-546: Was first applied to buildings of steel-framed construction of at least 10 stories in the late 19th century, a result of public amazement at the tall buildings being built in major American cities like New York City , Philadelphia , Boston , Chicago , Detroit , and St. Louis . The first steel-frame skyscraper was the Home Insurance Building , originally 10 stories with a height of 42 m or 138 ft, in Chicago in 1885; two additional stories were added. Some point to Philadelphia's 10-story Jayne Building (1849–50) as
24168-424: Was in 17th-century Edinburgh , Scotland, where a defensive city wall defined the boundaries of the city. Due to the restricted land area available for development, the houses increased in height instead. Buildings of 11 stories were common, and there are records of buildings as high as 14 stories.
