A load-bearing wall or bearing wall is a wall that is an active structural element of a building , which holds the weight of the elements above it, by conducting its weight to a foundation structure below it.
74-722: The Nissen Building is a 283 ft (86 m) 18-story skyscraper in Winston-Salem , Forsyth County, North Carolina , built in 1927. It was the largest building in the city, succeeding the Hotel Robert E. Lee , and the tallest building in North Carolina from 1927 to 1929, when it was succeeded by the Reynolds Building ; all three buildings were in Winston-Salem. The Nissen Building was named to
148-455: A Buttressed core . Trussed tube and X-bracing: Load-bearing wall Load -bearing walls are one of the earliest forms of construction. The development of the flying buttress in Gothic architecture allowed structures to maintain an open interior space, transferring more weight to the buttresses instead of to central bearing walls. In housing, load-bearing walls are most common in
222-541: 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
296-751: 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
370-399: 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
444-420: 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
518-454: 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
592-412: 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
666-571: 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
740-417: 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
814-521: 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

#1732780022142888-466: 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
962-469: 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,
1036-418: Is a wall that is an active structural element of a building — that is, it bears the weight of the elements above said wall, resting upon it by conducting its weight to a foundation structure. The materials most often used to construct load-bearing walls in large buildings are concrete , block , or brick . By contrast, a curtain wall provides no significant structural support beyond what
1110-406: 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
1184-433: 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
1258-466: Is necessary to bear its own materials or conduct such loads to a bearing wall. Load -bearing walls are one of the earliest forms of construction. The development of the flying buttress in Gothic architecture allowed structures to maintain an open interior space, transferring more weight to the buttresses instead of to central bearing walls. The Notre Dame Cathedral is an example of a load-bearing wall structure with flying buttresses. Depending on
1332-414: 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 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
1406-399: 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,
1480-419: 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

#17327800221421628-399: The wall studs . Using a top plate and a bottom plate, a wall can be constructed while it lies on its side, allowing for end-nailing of the studs between two plates, and then the finished wall can be tipped up vertically into place atop the wall sill; this not only improves accuracy and shortens construction time, but also produces a stronger wall. Due to the immense weight of skyscrapers ,
1702-643: The " Seven Sisters ", were built between 1947 and 1953; and one, the Main building of Moscow State University , was the tallest building in Europe for nearly four decades (1953–1990). Other skyscrapers in the style of Socialist Classicism were erected in East Germany ( Frankfurter Tor ), Poland ( PKiN ), Ukraine ( Hotel Moscow ), Latvia ( Academy of Sciences ), and other Eastern Bloc countries. Western European countries also began to permit taller skyscrapers during
1776-460: The 10th century described as resembling minarets . Nasir Khusraw in the early 11th century described some of them rising up to 14 stories, with roof gardens on the top floor complete with ox-drawn water wheels for irrigating them. Cairo in the 16th century had high-rise apartment buildings where the two lower floors were for commercial and storage purposes and the multiple stories above them were rented out to tenants . An early example of
1850-465: The 1880s that had enabled construction of tall multi-story buildings. This definition was based on the steel skeleton—as opposed to constructions of load-bearing masonry , which passed their practical limit in 1891 with Chicago's Monadnock Building . What is the chief characteristic of the tall office building? It is lofty. It must be tall. The force and power of altitude must be in it, the glory and pride of exaltation must be in it. It must be every inch
1924-600: The 1960s now use a tube design derived from Khan's structural engineering principles, examples including the construction of the World Trade Center , Aon Center , Petronas Towers , Jin Mao Building , and most other supertall skyscrapers since the 1960s. The strong influence of tube structure design is also evident in the construction of the current tallest skyscraper, the Burj Khalifa , which uses
1998-603: The 1960s, according to the CTBUH, the skyscraper has been reoriented away from a symbol for North American corporate power to instead communicate a city or nation's place in the world. Skyscraper construction entered a three-decades-long era of stagnation in 1930 due to the Great Depression and then World War II . Shortly after the war ended, Russia began construction on a series of skyscrapers in Moscow . Seven, dubbed
2072-807: 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
2146-690: The 57 m (187 ft) tall 1924 Marx House in Düsseldorf , the 65 m (213 ft) tall Borsigturm in Berlin , built in 1924, the 65 m (213 ft) tall Hansahochhaus in Cologne , Germany, built in 1925; the 61 m (200 ft) Kungstornen (Kings' Towers) in Stockholm , Sweden, which were built 1924–25; the 77 m (253 ft) Ullsteinhaus in Berlin, Germany, built in 1927;

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

2368-736: The Nissen Building on the site of a former YMCA between 1926 and 1927. William Lee Stoddart of New York City , known for the Battery Park Hotel in Asheville, North Carolina , was the architect. The building opened with a Bob-a-Link miniature golf course in the basement. The first tenants included the Civil Service Administration , Veterans Administration and the Office of Flying Safety . In 1931
2442-470: 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
2516-497: 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
2590-437: The base and walls of the lower floors must be extremely strong. Pilings are used to anchor the building to the bedrock underground. For example, the Burj Khalifa , the world's tallest building as well as the world's tallest structure, uses specially treated and mixed reinforced concrete . Over 45,000 cubic metres (59,000 cu yd) of concrete, weighing more than 110,000 t (120,000 short tons) were used to construct
2664-461: The building was in the process of being converted into 145 luxury apartments. A plan for condominiums was considered but dropped. Nissen Risk Capital LLC and HRI, using Holder Construction Co. as general contractor, began work in Summer 2004. Little Diversified Architectural Consulting and Acanthus Architecture Group provided architectural expertise. The lobby was being restored to the way it looked when

When the project was completed, the Nissen Building had 14,000 square feet (1,300 m) of commercial space and nearly 128,000 square feet (11,900 m) of residential space. 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

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
2886-648: 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
2960-651: 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;
3034-402: 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

3108-416: 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
3182-454: 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
3256-528: 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
3330-491: 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
3404-479: 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
3478-473: 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
3552-426: The light construction method known as " platform framing ", and each load-bearing wall sits on a wall sill plate which is mated to the lowest base plate . The sills are bolted to the masonry or concrete foundation . The top plate or ceiling plate is the top of the wall, which sits just below the platform of the next floor (at the ceiling). The base plate or floor plate is the bottom attachment point for
3626-409: The light construction method known as " platform framing ". In the birth of the skyscraper era, the concurrent rise of steel as a more suitable framing system first designed by William Le Baron Jenney , and the limitations of load-bearing construction in large buildings, led to a decline in the use of load-bearing walls in large-scale commercial structures. A load-bearing wall or bearing wall
3700-454: 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
3774-674: 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

#17327800221423848-435: 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
3922-406: 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,
3996-728: 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
4070-484: 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
4144-643: 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
4218-612: The street level shops included The Vogue clothing shop, the Bland Piano Company, Gladys' Lingerie Shop, the Belcher-Forlaw Shoe Company and Bobbitt's Nissen Drug. William and Ida Nissen lived on the 18th floor until 1954. The United States Air Force later became a major tenant. The Nissen Building was the first air-conditioned building in the Southeast . In May 1999, BB&T bought what
4292-438: 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
4366-715: 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
4440-482: 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
4514-587: The type of building and the number of floors, load-bearing walls are gauged to the appropriate thickness to carry the weight above them. Without doing so, it is possible that an outer wall could become unstable if the load exceeds the strength of the material used, potentially leading to the collapse of the structure. The primary function of this wall is to enclose or divide space of the building to make it more functional and useful. It provides privacy, affords security, and gives protection against heat, cold, sun or rain. In housing, load-bearing walls are most common in

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
4662-465: 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

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,

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

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
5032-476: 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
5106-671: The years immediately following World War II. Early examples include Edificio España (Spain) and Torre Breda (Italy). From the 1930s onward, skyscrapers began to appear in various cities in East and Southeast Asia as well as in Latin America . Finally, they also began to be constructed in cities in Africa , the Middle East , South Asia , and Oceania from the late 1950s. Skyscraper projects after World War II typically rejected
5180-621: 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
