71-602: The Jin Mao Tower ( simplified Chinese : 金 茂 大厦 ; traditional Chinese : 金 茂 大廈 ; pinyin : Jīnmào Dàshà ; Shanghainese : Cinmeu Dagho ; lit. ‘Golden Prosperity Building’), also known as the Jinmao Building or Jinmao Tower , is a 420.5-meter-tall (1,380 ft), 88-story (93 if counting the floors in the spire) landmark skyscraper in Lujiazui , Pudong , Shanghai , China. It contains

142-861: A shopping mall , offices and the Grand Hyatt Shanghai hotel which starts from the 53rd floor, which at the time of completion was the highest hotel in the world. Along with the Oriental Pearl Tower , the Shanghai World Financial Center and the Shanghai Tower it is part of the Lujiazui skyline seen from the Bund . It was the tallest building in China from its completion in 1999 until 2007, when it

213-951: A Newtonian flow; in fact it can be expressed as ( τ x x τ x y τ y x τ y y ) = ( x 0 0 − t ) ⋅ ( ∂ u ∂ x ∂ u ∂ y ∂ v ∂ x ∂ v ∂ y ) , {\displaystyle {\begin{pmatrix}\tau _{xx}&\tau _{xy}\\\tau _{yx}&\tau _{yy}\end{pmatrix}}={\begin{pmatrix}x&0\\0&-t\end{pmatrix}}\cdot {\begin{pmatrix}{\frac {\partial u}{\partial x}}&{\frac {\partial u}{\partial y}}\\{\frac {\partial v}{\partial x}}&{\frac {\partial v}{\partial y}}\end{pmatrix}},} i.e., an anisotropic flow with

284-443: A component—either a character or a sub-component called a radical —usually involves either a reduction in its total number of strokes , or an apparent streamlining of which strokes are chosen in what places—for example, the ⼓   ' WRAP ' radical used in the traditional character 沒 is simplified to ⼏   ' TABLE ' to form the simplified character 没 . By systematically simplifying radicals, large swaths of

355-434: A conversion table. While exercising such derivation, the following rules should be observed: Sample Derivations : The Series One List of Variant Characters reduces the number of total standard characters. First, amongst each set of variant characters sharing identical pronunciation and meaning, one character (usually the simplest in form) is elevated to the standard character set, and the rest are made obsolete. Then amongst

426-407: A few revised forms, and was implemented for official use by China's State Council on 5 June 2013. In Chinese, simplified characters are referred to by their official name 简化字 ; jiǎnhuàzì , or colloquially as 简体字 ; jiǎntǐzì . The latter term refers broadly to all character variants featuring simplifications of character form or structure, a practice which has always been present as

497-676: A floor-to-floor gross height of 4.0 m (13.1 ft) and net height of 2.7 m (8 ft 10 in). The building's anchor tenant is the five-star 555-room Grand Hyatt Shanghai hotel which occupies floors 53 to 87. It is one of the highest hotels in the world, second in Shanghai only to its sister property, the Shanghai Park Hyatt, occupying the 79th to 93rd floors of the immediately adjacent Shanghai World Financial Center . These have since been surpassed by The Ritz-Carlton, Hong Kong , which occupies floors 102 to 118 of

568-410: A generic tensorial identity: one can always find an expression of the viscosity as function of the flow velocity given any expression of the shear stress as function of the flow velocity. On the other hand, given a shear stress as function of the flow velocity, it represents a Newtonian flow only if it can be expressed as a constant for the gradient of the flow velocity. The constant one finds in this case

639-610: A newly coined phono-semantic compound : Removing radicals Only retaining single radicals Replacing with ancient forms or variants : Adopting ancient vulgar variants : Readopting abandoned phonetic-loan characters : Copying and modifying another traditional character : Based on 132 characters and 14 components listed in Chart 2 of the Complete List , the 1,753 derived characters found in Chart 3 can be created by systematically simplifying components using Chart 2 as

710-573: A part of the Chinese writing system. The official name tends to refer to the specific, systematic set published by the Chinese government, which includes not only simplifications of individual characters, but also a substantial reduction in the total number of characters through the merger of formerly distinct forms. According to Chinese palaeographer Qiu Xigui , the broadest trend in the evolution of Chinese characters over their history has been simplification, both in graphical shape ( 字形 ; zìxíng ),

781-609: A particle in a fluid passes through the fringes, a receiver detects the reflection of the fringe pattern. The signal can be processed, and from the fringe angle, the height and velocity of the particle can be extrapolated. The measured value of the wall velocity gradient is independent of the fluid properties, and as a result does not require calibration. Recent advancements in the micro-optic fabrication technologies have made it possible to use integrated diffractive optical elements to fabricate diverging fringe shear stress sensors usable both in air and liquid. A further measurement technique

852-411: A solid boundary will incur a shear stress at that boundary. The no-slip condition dictates that the speed of the fluid at the boundary (relative to the boundary) is zero; although at some height from the boundary, the flow speed must equal that of the fluid. The region between these two points is named the boundary layer . For all Newtonian fluids in laminar flow , the shear stress is proportional to

923-550: Is 1 m thick, 36 m high and 568 m long. It is composed of 20,500 m (720,000 cu ft) of reinforced concrete . The building employs an advanced structural engineering system of wind and earthquake engineering which fortify it against typhoon winds of up to 200 km/h (with the top swaying by a maximum of 75 cm or 30 in) and earthquakes of up to 7 on the Richter scale . The steel shafts have shear joints that act as shock absorbers to cushion

994-440: Is actually more complex than eliminated ones. An example is the character 搾 which is eliminated in favor of the variant form 榨 . The 扌   'HAND' with three strokes on the left of the eliminated 搾 is now seen as more complex, appearing as the ⽊   'TREE' radical 木 , with four strokes, in the chosen variant 榨 . Not all characters standardised in the simplified set consist of fewer strokes. For instance,

1065-423: Is also known as Zhuravskii shear stress formula after Dmitrii Ivanovich Zhuravskii , who derived it in 1855. Shear stresses within a semi-monocoque structure may be calculated by idealizing the cross-section of the structure into a set of stringers (carrying only axial loads) and webs (carrying only shear flows ). Dividing the shear flow by the thickness of a given portion of the semi-monocoque structure yields

1136-454: Is derived. Merging homophonous characters: Adapting cursive shapes ( 草書楷化 ): Replacing a component with a simple arbitrary symbol (such as 又 and 乂 ): Omitting entire components : Omitting components, then applying further alterations : Structural changes that preserve the basic shape Replacing the phonetic component of phono-semantic compounds : Replacing an uncommon phonetic component : Replacing entirely with

1207-667: Is named dynamic viscosity . For an isotropic Newtonian flow, it is a scalar, while for anisotropic Newtonian flows, it can be a second-order tensor. The fundamental aspect is that for a Newtonian fluid, the dynamic viscosity is independent of flow velocity (i.e., the shear stress constitutive law is linear ), while for non-Newtonian flows this is not true, and one should allow for the modification τ ( u ) = μ ( u ) ∇ u . {\displaystyle {\boldsymbol {\tau }}(\mathbf {u} )=\mu (\mathbf {u} ){\boldsymbol {\nabla }}\mathbf {u} .} This no longer Newton's law but

1278-413: Is non-Newtonian since the viscosity depends on flow velocity. This non-Newtonian flow is isotropic (the matrix is proportional to the identity matrix), so the viscosity is simply a scalar: μ ( u ) = 1 u . {\displaystyle \mu (u)={\frac {1}{u}}.} This relationship can be exploited to measure the wall shear stress. If a sensor could directly measure

1349-412: Is nonuniform (depends on space coordinates) and transient, but is independent of the flow velocity: μ ( x , t ) = ( x 0 0 − t ) . {\displaystyle {\boldsymbol {\mu }}(x,t)={\begin{pmatrix}x&0\\0&-t\end{pmatrix}}.} This flow is therefore Newtonian. On the other hand, a flow in which

1420-813: Is now discouraged. A State Language Commission official cited "oversimplification" as the reason for restoring some characters. The language authority declared an open comment period until 31 August 2009, for feedback from the public. In 2013, the List of Commonly Used Standard Chinese Characters was published as a revision of the 1988 lists; it included a total of 8105 characters. It included 45 newly recognized standard characters that were previously considered variant forms, as well as official approval of 226 characters that had been simplified by analogy and had seen wide use but were not explicitly given in previous lists or documents. Singapore underwent three successive rounds of character simplification , eventually arriving at

1491-623: Is referred to as the " big seal script ". The traditional narrative, as also attested in the Shuowen Jiezi dictionary ( c.  100 AD ), is that the Qin small seal script that would later be imposed across China was originally derived from the Zhou big seal script with few modifications. However, the body of epigraphic evidence comparing the character forms used by scribes gives no indication of any real consolidation in character forms prior to

1562-409: Is that of slender wall-mounted micro-pillars made of the flexible polymer polydimethylsiloxane , which bend in reaction to the applying drag forces in the vicinity of the wall. The sensor thereby belongs to the indirect measurement principles relying on the relationship between near-wall velocity gradients and the local wall-shear stress. The electro-diffusional method measures the wall shear rate in

1633-422: Is the dynamic viscosity , u is the flow velocity, and y is the distance from the wall. It is used, for example, in the description of arterial blood flow , where there is evidence that it affects the atherogenic process. Pure shear stress is related to pure shear strain , denoted γ , by the equation τ = γ G , {\displaystyle \tau =\gamma G,} where G

1704-517: Is the shear modulus of the isotropic material, given by G = E 2 ( 1 + ν ) . {\displaystyle G={\frac {E}{2(1+\nu )}}.} Here, E is Young's modulus and ν is Poisson's ratio . Beam shear is defined as the internal shear stress of a beam caused by the shear force applied to the beam: τ := f Q I b , {\displaystyle \tau :={\frac {fQ}{Ib}},} where The beam shear formula

1775-851: Is the dynamic viscosity of the flow. Considering a 2D space in Cartesian coordinates ( x , y ) (the flow velocity components are respectively ( u , v ) ), the shear stress matrix given by ( τ x x τ x y τ y x τ y y ) = ( x ∂ u ∂ x 0 0 − t ∂ v ∂ y ) {\displaystyle {\begin{pmatrix}\tau _{xx}&\tau _{xy}\\\tau _{yx}&\tau _{yy}\end{pmatrix}}={\begin{pmatrix}x{\frac {\partial u}{\partial x}}&0\\0&-t{\frac {\partial v}{\partial y}}\end{pmatrix}}} represents

1846-547: Is used instead of 叠 in regions using traditional characters. The Chinese government stated that it wished to keep Chinese orthography stable. The Chart of Generally Utilized Characters of Modern Chinese was published in 1988 and included 7000 simplified and unsimplified characters. Of these, half were also included in the revised List of Commonly Used Characters in Modern Chinese , which specified 2500 common characters and 1000 less common characters. In 2009,

1917-670: The Chinese language , with the other being traditional characters . Their mass standardization during the 20th century was part of an initiative by the People's Republic of China (PRC) to promote literacy, and their use in ordinary circumstances on the mainland has been encouraged by the Chinese government since the 1950s. They are the official forms used in mainland China and Singapore , while traditional characters are officially used in Hong Kong , Macau , and Taiwan . Simplification of

1988-628: The International Commerce Center in Hong Kong. However, the tallest building to be used exclusively as a hotel is the JW Marriott Marquis Dubai . Additionally, the world's longest laundry chute runs down the full length of the tower to the basement, incorporating buffers to slow the laundry during its descent. The Hyatt's famous barrel-vaulted atrium starts at the 56th floor and extends upwards to

2059-412: The number 8 , associated with prosperity in Chinese culture . The 88 floors (93 if the spire floors are counted) are divided into 16 segments, each of which is 1/8 shorter than the 16-story base. The tower is built around an octagon-shaped concrete shear wall core surrounded by 8 exterior composite supercolumns and 8 exterior steel columns. Three sets of 8 two-story high outrigger trusses connect

2130-559: The strain rate in the fluid, where the viscosity is the constant of proportionality. For non-Newtonian fluids , the viscosity is not constant. The shear stress is imparted onto the boundary as a result of this loss of velocity. For a Newtonian fluid, the shear stress at a surface element parallel to a flat plate at the point y is given by τ ( y ) = μ ∂ u ∂ y , {\displaystyle \tau (y)=\mu {\frac {\partial u}{\partial y}},} where Specifically,

2201-407: The "Dot" stroke : The traditional components ⺥ and 爫 become ⺈ : The traditional component 奐 becomes 奂 : Shear stress Shear stress (often denoted by τ , Greek : tau ) is the component of stress coplanar with a material cross section . It arises from the shear force , the component of force vector parallel to the material cross section. Normal stress , on

The initiatives following the founding of the Qin dynasty (221–206 BC) to universalize the use of their small seal script across

2343-482: The 1986 General List of Simplified Chinese Characters , hereafter the General List . All characters simplified this way are enumerated in Chart 1 and Chart 2 in the 1986 Complete List . Characters in both charts are structurally simplified based on similar set of principles. They are separated into two charts to clearly mark those in Chart 2 as 'usable as simplified character components', based on which Chart 3

2414-520: The 1986 mainland China revisions. Unlike in mainland China, Singapore parents have the option of registering their children's names in traditional characters. Malaysia also promulgated a set of simplified characters in 1981, though completely identical to the mainland Chinese set. They are used in Chinese-language schools. All characters simplified this way are enumerated in Charts 1 and 2 of

It is one of the tallest atria in the world, the tallest being the Burj Al Arab 's. The hotel floors also feature: The Skywalk, a 1,520 m (16,400 sq ft) indoor observation deck with a capacity of 1,000+ people, occupies

2556-531: The 88th floor of the building. In addition to the panoramic views of Shanghai, it offers a topside view of the hotel atrium below. It also includes a small post office . Access is through two express elevators from the basement that travel at 9.1 m/s and take 45 seconds to reach the top. As of 2009, admission to the 88th floor costs 88 RMB for adults and 45 RMB for children. Simplified Chinese characters Simplified Chinese characters are one of two standardized character sets widely used to write

2627-470: The Chinese government published a major revision to the list which included a total of 8300 characters. No new simplifications were introduced. In addition, slight modifications to the orthography of 44 characters to fit traditional calligraphic rules were initially proposed, but were not implemented due to negative public response. Also, the practice of unrestricted simplification of rare and archaic characters by analogy using simplified radicals or components

2698-494: The applied force vector, i.e., with surface normal vector perpendicular to the force. Wall shear stress expresses the retarding force (per unit area) from a wall in the layers of a fluid flowing next to the wall. It is defined as: τ w := μ ∂ u ∂ y | y = 0 , {\displaystyle \tau _{w}:=\mu \left.{\frac {\partial u}{\partial y}}\right|_{y=0},} where μ

The 3-level basement has a food court, while the first two floors include the Hyatt 's conference and banquet facilities. The first six floors include a shopping mall, restaurants, and nightclubs, include Pu-J's. The lower 50 floors (in the first 4 segments of the tower) are made up of 123,000 m (1,320,000 sq ft) of offices, divided into 5 elevator zones (3-6, 7-17, 18-29, 30-40, and 41-50). Office spaces are open-plan (column-free), with

2840-428: The character set are altered. Some simplifications were based on popular cursive forms that embody graphic or phonetic simplifications of the traditional forms. In addition, variant characters with identical pronunciation and meaning were reduced to a single standardized character, usually the simplest among all variants in form. Finally, many characters were left untouched by simplification and are thus identical between

2911-407: The chosen variants, those that appear in the "Complete List of Simplified Characters" are also simplified in character structure accordingly. Some examples follow: Sample reduction of equivalent variants : Ancient variants with simple structure are preferred : Simpler vulgar forms are also chosen : The chosen variant was already simplified in Chart 1 : In some instances, the chosen variant

2982-471: The columns to the core at six of the floors to provide additional support. The foundations rest on 1,062 high-capacity steel piles driven 83.5 m (274 ft) deep in the ground to compensate for poor upper-strata soil conditions. At the time of construction, these were the longest steel piles ever used for a land-based building. The piles are capped by a 4 m-thick concrete raft 19.6 m (64 ft) underground. The basement's surrounding slurry wall

3053-473: The country's writing system as a serious impediment to its modernization. In 1916, a multi-part English-language article entitled "The Problem of the Chinese Language" co-authored by the Chinese linguist Yuen Ren Chao (1892–1982) and poet Hu Shih (1891–1962) has been identified as a turning point in the history of the Chinese script—as it was one of the first clear calls for China to move away from

3124-476: The early 20th century. In 1909, the educator and linguist Lufei Kui formally proposed the use of simplified characters in education for the first time. Over the following years—marked by the 1911 Xinhai Revolution that toppled the Qing dynasty , followed by growing social and political discontent that further erupted into the 1919 May Fourth Movement —many anti-imperialist intellectuals throughout China began to see

3195-634: The first official list of simplified forms was published, consisting of 324 characters collated by Peking University professor Qian Xuantong . However, fierce opposition within the KMT resulted in the list being rescinded in 1936. Work throughout the 1950s resulted in the 1956 promulgation of the Chinese Character Simplification Scheme , a draft of 515 simplified characters and 54 simplified components, whose simplifications would be present in most compound characters. Over

3266-463: The first round—but was massively unpopular and never saw consistent use. The second round of simplifications was ultimately retracted officially in 1986, well after they had largely ceased to be used due to their unpopularity and the confusion they caused. In August 2009, China began collecting public comments for a revised list of simplified characters; the resulting List of Commonly Used Standard Chinese Characters lists 8,105 characters, including

3337-430: The flat plate above mentioned), states that shear tensor (a second-order tensor) is proportional to the flow velocity gradient (the velocity is a vector, so its gradient is a second-order tensor): τ ( u ) = μ ∇ u . {\displaystyle {\boldsymbol {\tau }}(\mathbf {u} )=\mu {\boldsymbol {\nabla }}\mathbf {u} .} The constant of proportionality

3408-475: The following decade, the Script Reform Committee deliberated on characters in the 1956 scheme, collecting public input regarding the recognizability of variants, and often approving forms in small batches. Parallel to simplification, there were also initiatives aimed at eliminating the use of characters entirely and replacing them with pinyin as an official Chinese alphabet, but this possibility

3479-459: The founding of the Qin. The Han dynasty (202 BC – 220 AD) that inherited the Qin administration coincided with the perfection of clerical script through the process of libian . Eastward spread of Western learning Though most closely associated with the People's Republic, the idea of a mass simplification of character forms first gained traction in China during

3550-413: The gradient of the velocity profile at the wall, then multiplying by the dynamic viscosity would yield the shear stress. Such a sensor was demonstrated by A. A. Naqwi and W. C. Reynolds. The interference pattern generated by sending a beam of light through two parallel slits forms a network of linearly diverging fringes that seem to originate from the plane of the two slits (see double-slit experiment ). As

3621-466: The increased usage of 朙 was followed by proliferation of a third variant: 眀 , with 目 'eye' on the left—likely derived as a contraction of 朙 . Ultimately, 明 became the character's standard form. The Book of Han (111 AD) describes an earlier attempt made by King Xuan of Zhou ( d.  782 BC ) to unify character forms across the states of ancient China , with his chief chronicler having "[written] fifteen chapters describing" what

The exterior curtain wall is made of glass, stainless steel , aluminum , and granite and is criss-crossed by complex latticework cladding made of aluminum alloy pipes. Official dedication was August 28, 1998, a date also chosen with the number 8 in mind. The building

3763-465: The left, with the 月 'Moon' component on the right. Li Si ( d.  208 BC ), the Chancellor of Qin, attempted to universalize the Qin small seal script across China following the wars that had politically unified the country for the first time. Li prescribed the 朙 form of the word for 'bright', but some scribes ignored this and continued to write the character as 明 . However,

3834-405: The liquid phase from microelectrodes under limiting diffusion current conditions. A potential difference between an anode of a broad surface (usually located far from the measuring area) and the small working electrode acting as a cathode leads to a fast redox reaction. The ion disappearance occurs only on the microprobe active surface, causing the development of the diffusion boundary layer, in which

3905-402: The most prominent Chinese authors of the 20th century, stated that "if Chinese characters are not destroyed, then China will die" ( 漢字不滅，中國必亡 ). During the 1930s and 1940s, discussions regarding simplification took place within the ruling Kuomintang (KMT) party. Many members of the Chinese intelligentsia maintained that simplification would increase literacy rates throughout the country. In 1935,

3976-428: The other hand, arises from the force vector component perpendicular to the material cross section on which it acts. The formula to calculate average shear stress τ or force per unit area is: τ = F A , {\displaystyle \tau ={F \over A},} where F is the force applied and A is the cross-sectional area. The area involved corresponds to the material face parallel to

4047-430: The public and quickly fell out of official use. It was ultimately formally rescinded in 1986. The second-round simplifications were unpopular in large part because most of the forms were completely new, in contrast to the familiar variants comprising the majority of the first round. With the rescission of the second round, work toward further character simplification largely came to an end. In 1986, authorities retracted

4118-465: The recently conquered parts of the empire is generally seen as being the first real attempt at script reform in Chinese history. Before the 20th century, variation in character shape on the part of scribes, which would continue with the later invention of woodblock printing , was ubiquitous. For example, prior to the Qin dynasty (221–206 BC) the character meaning 'bright' was written as either 明 or 朙 —with either 日 'Sun' or 囧 'window' on

4189-481: The same set of simplified characters as mainland China. The first round was promulgated by the Ministry of Education in 1969, consisting of 498 simplified characters derived from 502 traditional characters. A second round of 2287 simplified characters was promulgated in 1974. The second set contained 49 differences from the mainland China system; these were removed in the final round in 1976. In 1993, Singapore adopted

4260-467: The second round completely, though they had been largely fallen out of use within a year of their initial introduction. That year, the authorities also promulgated a final version of the General List of Simplified Chinese Characters . It was identical to the 1964 list save for 6 changes—including the restoration of 3 characters that had been simplified in the first round: 叠 , 覆 , 像 ; the form 疊

4331-658: The shear stress. Thus, the maximum shear stress will occur either in the web of maximum shear flow or minimum thickness. Constructions in soil can also fail due to shear; e.g. , the weight of an earth-filled dam or dike may cause the subsoil to collapse, like a small landslide . The maximum shear stress created in a solid round bar subject to impact is given by the equation τ = 2 U G V , {\displaystyle \tau =2{\sqrt {\frac {UG}{V}}},} where Furthermore, U = U rotating + U applied , where Any real fluids ( liquids and gases included) moving along

4402-497: The traditional and simplified Chinese orthographies. The Chinese government has never officially announced the completion of the simplification process after the bulk of characters were introduced by the 1960s. In the wake of the Cultural Revolution , a second round of simplified characters was promulgated in 1977—largely composed of entirely new variants intended to artificially lower the stroke count, in contrast to

4473-833: The traditional character 強 , with 11 strokes is standardised as 强 , with 12 strokes, which is a variant character. Such characters do not constitute simplified characters. The new standardized character forms shown in the Characters for Publishing and revised through the Common Modern Characters list tend to adopt vulgar variant character forms. Since the new forms take vulgar variants, many characters now appear slightly simpler compared to old forms, and as such are often mistaken as structurally simplified characters. Some examples follow: The traditional component 釆 becomes 米 : The traditional component 囚 becomes 日 : The traditional "Break" stroke becomes

4544-522: The use of characters entirely. Instead, Chao proposed that the language be written with an alphabet, which he saw as more logical and efficient. The alphabetization and simplification campaigns would exist alongside one another among the Republican intelligentsia for the next several decades. Recent commentators have echoed some contemporary claims that Chinese characters were blamed for the economic problems in China during that time. Lu Xun , one of

In 1965, the PRC published the List of Commonly Used Characters for Printing  [ zh ] (hereafter Characters for Printing ), which included standard printed forms for 6196 characters, including all of the forms from the 1956 scheme. A second round of simplified characters was promulgated in 1977, but was poorly received by

It reportedly has a daily maintenance cost of 1 million RMB ( US$ 121,000). The building has 3 main entrances to the lobby : two for the office portion and one for the hotel. The basement has express elevators to the observation deck and a parking area for 600 vehicles and 7,500 bicycles. In total, 61 Mitsubishi elevators and 19 escalators carry visitors throughout
