El Burj Khalifa en Dubai, Emiratos Árabes Unidos.

La estructura artificial más alta del mundo es el Burj Khalifa de 829,8 metros de altura (2722 pies) en Dubai (de los Emiratos Árabes Unidos ). El edificio ganó el título oficial de " edificio más alto del mundo " y la estructura autoportante más alta en su inauguración el 9 de enero de 2010. Burj Khalifa fue desarrollado por Emaar properties , diseñado por Skidmore, Owings y Merrill y construido por BESIX . Samsung Construction y Arabtec . [1] La segunda estructura autoportante más alta y la torre más alta del mundo es el Tokyo Skytree.. La estructura arriostrada más alta es el mástil KVLY-TV .

El Consejo de Edificios Altos y Hábitat Urbano , una organización que certifica los edificios como "los más altos del mundo", reconoce un edificio solo si al menos el 50% de su altura está formado por placas de piso que contienen una superficie habitable. [2] Las estructuras que no cumplen este criterio, como la Torre CN , se definen como " torres ".

Hay docenas de torres de transmisión de radio y televisión que miden más de 600 metros (aproximadamente 2,000 pies) de altura, y solo las más altas están registradas en fuentes de información disponibles públicamente.

Debate sobre definiciones [ editar ]

La evaluación de la altura de las estructuras artificiales ha sido controvertida. Diferentes organizaciones han utilizado varios estándares, lo que ha significado que el título de estructura o edificio más alto del mundo haya cambiado según los estándares que se hayan aceptado. El Consejo de Edificios Altos y Hábitat Urbano ha cambiado sus definiciones con el tiempo. Parte de la controversia con respecto a las definiciones y evaluación de estructuras y edificios altos ha incluido lo siguiente:

  • la definición de una estructura, un edificio y una torre
  • si una estructura, edificio o torre en construcción debe incluirse en cualquier evaluación
  • si una estructura, edificio o torre debe abrirse oficialmente antes de que se evalúe
  • si las estructuras construidas y que se elevan por encima del agua deben incluir su altura bajo el agua en cualquier evaluación.
  • si una estructura, edificio o torre arriostrada se evalúa en la misma categoría que las estructuras autoportantes.

Dentro de una definición aceptada de un edificio, la controversia adicional ha incluido los siguientes factores:

  • si solo se considera la altura habitable del edificio
  • si las torres de comunicación con galerías de observación deben considerarse "habitables" en este sentido
  • si se deben incluir en la evaluación antenas en los tejados , plataformas de observación o cualquier otra arquitectura que no forme un piso habitable
  • si un piso construido en un nivel alto de una torre de telecomunicaciones o de observación debe cambiar la definición de la torre a la de un "edificio"

Estructuras más altas [ editar ]

Mástil de radio de Varsovia , el poseedor del récord de altura de 1974 a 1991
La CN Tower en Toronto , Ontario , fue la estructura independiente más alta del mundo desde 1975 hasta 2007.

Esta categoría no requiere que la estructura esté "oficialmente" abierta, pero sí requiere que esté "rematada".

La estructura artificial más alta es Burj Khalifa , un rascacielos en Dubai que alcanzó los 829,8 m (2722 pies) de altura el 17 de enero de 2009. [3] El 8 de abril de 2008 se había construido más alto que el mástil KVLY-TV en Dakota del Norte. , EE.UU. [4] Ese septiembre superó oficialmente el mástil de radio de Varsovia de 646,38 m (2120,7 pies) de Polonia , que se mantuvo de 1974 a 1991, para convertirse en la estructura más alta jamás construida. Las torres de celosía arriostradas como estos mástiles habían tenido el récord mundial de altura desde 1954.

La plataforma Petronius se encuentra a 610 m (2.000 pies) del fondo del mar, lo que lleva a algunos, incluido Guinness World Records 2007, a reclamarla como la estructura independiente más alta del mundo. Sin embargo, se debate si se debe contar la altura bajo el agua, de la misma manera que se ignora la altura bajo el suelo en los edificios. La plataforma Troll A mide 472 m (1549 pies), sin que ninguna parte de esa altura esté sostenida por cables. La pierna de tensiónEl tipo de plataforma petrolífera tiene alturas bajo el agua aún mayores, con varios ejemplos de más de 1000 m (3300 pies) de profundidad. Sin embargo, estas plataformas no se consideran estructuras constantes ya que la gran mayoría de su altura está formada por la longitud de los tendones que unen las plataformas flotantes al fondo del mar. A pesar de esto, Guinness World Records 2009 enumeró la plataforma de piernas de tensión Ursa como la estructura más alta del mundo con una altura total de 1.306 m (4.285 pies). La plataforma Magnolia Tension-leg en el Golfo de México es aún más alta con una altura total de 1,432 m (4,698 pies).

Taipei 101 en Taipei, Taiwán, estableció récords en tres de las cuatro categorías de rascacielos en el momento de su inauguración en 2004; en el momento en que se inauguró el Burj Khalifa en 2010, seguía siendo el edificio habitado más alto del mundo 509,2 m (1.671 pies) medido a su altura arquitectónica (aguja). La altura de su techo 449,2 m (1474 pies) y el piso más alto ocupado 439,2 m (1441 pies) habían sido superados por el Shanghai World Financial Center con alturas correspondientes de 487 y 474 m (1598 y 1555 pies). Willis Tower (anteriormente Sears Tower) fue la más alta en la categoría final: la mayor altura hasta la parte superior de la antena de cualquier edificio en el mundo a 527 m (1729 pies).

Burj Khalifa rompió el récord de altura en las cuatro categorías de edificios terminados.

Estructura más alta por categoría [ editar ]

Debido a los desacuerdos sobre cómo medir la altura y clasificar las estructuras, los ingenieros han creado varias definiciones para las categorías de edificios y otras estructuras. Una medida incluye la altura absoluta de un edificio, otra incluye solo agujas y otras características arquitectónicas permanentes, pero no antenas . La tradición de incluir la aguja en la parte superior de un edificio y no incluir la antena se remonta a la rivalidad entre el edificio Chrysler y 40 Wall Street . Un ejemplo moderno es que la antena en la parte superior de la Torre Willis (anteriormente Torre Sears) no se considera parte de su altura arquitectónica, mientras que se cuentan las agujas en la parte superior de las Torres Gemelas Petronas .

Nota: La siguiente tabla es una lista de la estructura completa más alta en cada una de las categorías estructurales a continuación. Para obtener una lista de estructuras por función, consulte la lista más adelante en el artículo. Solo puede haber una estructura en cada categoría, a menos que la más alta sea la misma para más de una estructura en la misma categoría.

Tallest destroyed structures by category, not surpassed by existing structures[edit]

There are some destroyed architectural structures which were taller than the tallest existing structure of their type. There are also destroyed structures omitted from this list that had been surpassed in height prior to being destroyed.

Tallest structure by function[edit]

* "Mixed-use" is defined as having three or more real estate uses (such as retail, office, hotel, etc.) that are physically and functionally integrated in a single property and are mutually supporting.[18]

Tallest buildings[edit]

Up until the late 1990s, the definition of “tallest building” was not altogether clear. It was generally understood to be the height of the building to the top of its architectural elements including spires, but not including "temporary" structures (such as antennas or flagpoles), which could be added or changed relatively easily without requiring major changes to the building's design. Other criteria for height measurement generally were not considered, which occasionally caused some controversy.

One historic case involved the building now famous for the Times Square Ball. Known as One Times Square (at 1475 Broadway in Midtown Manhattan), it was the headquarters for The New York Times, which gave Times Square its name. Completed in 1905, it reached a height of 364 feet (111 meters) to its roof, or 420 feet (130 meters) including its rooftop flagpole, which the Times hoped would give it a record high status. But because a flagpole is not an integral architectural part of a building, One Times Square was not generally considered to be taller than the 390-foot-high (120 m) Park Row Building in Lower Manhattan, which was therefore still New York's tallest.[19]

A bigger controversy was the rivalry between two New York skyscrapers built in the Roaring Twenties — the Chrysler Building and 40 Wall Street. The latter was 927 feet (283 meters) tall, had a shorter pinnacle, and had a much higher top occupied floor (the second category in the 1996 criteria for tallest building).[20] In contrast, the Chrysler Building employed a very long 125-foot (38 m) spire secretly assembled inside the building to claim the title of world's tallest building with a total height of 1,048 feet (319 m), despite having a lower top occupied floor and a shorter height when both buildings' spires are not counted in their heights.[21] Although the architects of record for 40 Wall were H. Craig Severance and Yasuo Matsui, the firm of Shreve & Lamb (who also designed the Empire State Building) served as consulting architects. They wrote a newspaper article claiming that 40 Wall was actually the tallest, since it contained the world's highest usable floor. They pointed out that the observation deck of 40 Wall was nearly 100 feet (30 m) higher than the top floor of the Chrysler, whose surpassing spire was strictly ornamental and essentially inaccessible.[22] Despite the protest, the Chrysler Building was generally accepted as the tallest building in the world for almost a year, until it was surpassed by the Empire State Building’s 1,250 feet (380 meters) in 1931.

That was in turn surpassed by the 1,368-foot-high (417 m) twin towers of New York’s original World Trade Center in 1972, which were in turn surpassed by the Sears Tower in Chicago in 1974. Now called the Willis Tower (since 2009) it was 1,451 feet (442 meters) to its flat rooftop, or 1,518 feet (463 meters) including its original antennas.[23] But in 1978 One World Trade Center (commonly known as the north tower) attained a taller absolute height when it added its 360-foot (110 m) new broadcasting antenna, for a total height of 1,728 feet (527 meters). The WTC north tower maintained this height record (including its antenna) from 1978 until 2000, when the owners of the Willis Tower extended its broadcasting antennae for a total height of 1,729 feet (527 meters).[23] Thus the status of the Willis Tower as the “totally” tallest was restored in the face of a new threat looming in the Far East — the “Siamese Twins.”

The Petronas Towers remain the tallest twin towers in the world.

A major controversy erupted upon completion of the Petronas Towers in Kuala Lumpur, Malaysia in 1998. These twin towers, at 1,483 feet (452 meters), had a higher architectural height (spires, not antennas), but a lower absolute pinnacle height and a lower top occupied floor than the Willis Tower in Chicago. Counting buildings as structures with floors throughout, and with antenna masts excluded, the Willis was still considered the tallest at that time. Excluding their spires, which are 9 meters (30 feet) higher than the flat roof of Willis, the Petronas Towers are not taller than Willis. At their convention in Chicago, the Council on Tall Buildings and Urban Habitat (CTBUH) found the Willis Tower (without its antennas) to be the third-tallest building, and the Petronas Towers (with their spires) to be the world's two tallest buildings.[19]

Responding to the ensuing controversy, the CTBUH then revised their criteria and defined four categories in which the world's tallest building can be measured,[24] retaining the old criterion of height to architectural top, and adding three new categories:[19]

  1. Height to Architectural Top (including spires and pinnacles, but not antennas, masts or flagpoles). This measurement is the most widely used and is used to define the rankings of the 100 Tallest Buildings in the World.
  2. Highest Occupied Floor
  3. Height to Top of Roof (omitted from criteria from November 2009 onwards)[25]
  4. Height to Tip

The height-to-roof criterion was discontinued because relatively few modern tall buildings possess flat rooftops, making this criterion difficult to determine and measure.[26] The CTBUH has further clarified their definitions of building height, including specific criteria concerning subbasements and ground level entrances (height measured from lowest, significant, open-air, pedestrian entrance rather than from a previously undefined "main entrance"), building completion (must be topped out both structurally and architecturally, fully clad, and able to be occupied), condition of the highest occupied floor (must be continuously used by people living or working and be conditioned, thus including observation decks, but not mechanical floors) and other aspects of tall buildings.[26][27]

The height is measured from the level of the lowest, significant, open-air, pedestrian entrance. At the time, the Willis Tower held first place in the second and third categories, the Petronas Towers held the first category, and the original WTC north tower held the fourth (height to tip) category with its antenna.[19] In 2000, however, a new antenna mast was placed on the Willis Tower, giving it the record in the fourth category. On April 20, 2004, the 101-storey Taipei 101 in Taipei, Taiwan, was completed, taking the world record for the first three categories. On July 21, 2007, it was announced that Burj Khalifa in Dubai, UAE, had surpassed Taipei 101. Since its completion in early 2010, Burj Khalifa leads in all categories (the first building to do so) with its spire height of 2,722 feet (830 meters).

Before Burj Khalifa was completed, Willis Tower led in the height-to-tip category with 1,729 feet (527 meters) after its antenna was extended in 2000, making Willis Tower slightly taller height-to-tip than the WTC north tower's antenna that measured 1,728 feet (527 meters). After the September 11, 2001, attacks, the WTC became the world's tallest two buildings to be destroyed or demolished. They took that distinction from the Singer Building, which stood 612 feet (187 meters) tall until the late 1960s where One Liberty Plaza now stands right across Church Street from the WTC site.

A different superlative for skyscrapers is their number of floors. The original World Trade Center set that record at 110 in the early 1970s, and this was not surpassed until the Burj Khalifa opened in 2010.

Structures such as the CN Tower, the Ostankino Tower and the Oriental Pearl Tower are excluded from these categories because they are not "habitable buildings", which are defined as frame structures made with floors and walls throughout.[2]

History of record holders in each CTBUH category[edit]

Tallest freestanding structures on land[edit]

Freestanding structures must not be supported by guy wires, the sea or other types of support. It therefore does not include guyed masts, partially guyed towers and drilling platforms but does include towers, skyscrapers (pinnacle height) and chimneys.(See also history of tallest skyscrapers.)

The world's tallest freestanding structure on land is defined as the tallest self-supporting artificial structure that stands above ground. This definition is different from that of world's tallest building or world's tallest structure based on the percentage of the structure that is occupied and whether or not it is self-supporting or supported by exterior cables. Likewise, this definition does not count structures that are built underground or on the seabed, such as the Petronius Platform in the Gulf of Mexico. Visit world's tallest structure by category for a list of various other definitions.

The tallest freestanding structure on land is the Burj Khalifa in Dubai, United Arab Emirates. The building surpassed the height of the previous record holder, the 553.3 m (1,815 ft) CN Tower in Toronto, Ontario, on September 12, 2007. It was completed in 2010, with final height of 829.8 m (2,722 ft).

History[edit]

The following is a list of structures that have held the title as the tallest freestanding structure on land.

Diagram of the principal high buildings of the Old World, 1884

Notable mentions include the Pharos (lighthouse) of Alexandria, built in the third century BC and estimated between 115–135 m (377–443 ft). It was the world's tallest non-pyramidal structure for many centuries. Another notable mention includes the Jetavanaramaya stupa in Anuradhapura, Sri Lanka, which was built in the third century, and was similarly tall at 122 m (400 ft). These were both the world's tallest or second-tallest non-pyramidal structure for over a thousand years.

The tallest secular building between the collapse of the Pharos and the erection of the Washington Monument may have been the Torre del Mangia in Siena, which is 102 m (335 ft) tall, and was constructed in the first half of the fourteenth century, and the 97-metre-tall (318 ft) Torre degli Asinelli in Bologna, also Italy, built between 1109 and 1119.

World's highest observation deck[edit]

Timeline of development of world's highest observation deck since inauguration of Eiffel Tower.

Higher observation decks have existed on mountain tops or cliffs, rather than on tall structures. The Grand Canyon Skywalk, constructed in 2007, protrudes 21 m (70 ft) over the west rim of the Grand Canyon and is approximately 1,100 m (3,600 ft) above the Colorado River, making it the highest of these types of structures.[citation needed]

Timeline of guyed structures on land[edit]

As most of the tallest structures are guyed masts, here is a timeline of world's tallest guyed masts, since the beginning of radio technology.

As many large guyed masts were destroyed at the end of World War II, the dates for the years between 1945 and 1950 may be incorrect. If Wusung Radio Tower survived World War II, it was the tallest guyed structure shortly after World War II.

Tallest towers[edit]

Towers include observation towers, monuments and other structures not generally considered to be "habitable buildings", they are meant for "regular access by humans, but not for living in or office work, and are self-supporting or freestanding, which means no guy-wires for support", meaning it excludes from this list of continuously habitable buildings and skyscrapers as well as radio and TV masts.

Bridge towers or pylons, chimneys, transmission towers, and most large statues allow human access for maintenance, but not as part of their normal operation, and are therefore not considered to be towers.

The Tokyo Skytree, completed in February 2012, is 634 m (2,080 ft), making it the tallest tower, and second-tallest freestanding structure in the world.[36][37][38]

History of tallest tower[edit]

Tokyo Tower held the record of being the tallest tower in the world from 1958 to 1967. In addition, it held the record of being the tallest structure in Japan from 1958 to 2011, when the Tokyo Skytree (the current tallest tower in the world) surpassed it.

The following is a list of structures that have historically held the title as the tallest towers in the world.

Tallest structures, freestanding structures, and buildings[edit]

Burj Khalifa and other tallest structures

The list categories are:

  • The structures (supported) list uses pinnacle height and includes architectural structures of any type that might use some external support constructions like cables and are fully built in air. Only the three tallest are listed, as more than fifty US TV masts have stated heights of 600–610 metres (1,970–2,000 ft).
  • The structures (media supported) list uses pinnacle height and includes architectural structures of any type that are not totally built in the air but are using support from other, denser media like salt water. All structures greater than 500 metres (1,640 ft) are listed.
  • The freestanding structures list uses pinnacle height and includes structures over 500 metres (1,640 ft) that do not use guy-wires or other external supports. This means truly free standing on its own or, in similar sense, non-supported structures.
  • The building list uses architectural height (excluding antennas) and includes only buildings, defined as consisting of habitable floors. Both of these follow CTBUH guidelines. All supertall buildings (450 m and higher) are listed.

Notes:

  • Eight buildings appear on the freestanding structures category list with heights different from another category. This is due to the different measurement specifications of those lists.
  • Only current heights and, where reasonable, target heights are listed. Historical heights of structures that no longer exist, for example, for having collapsed, are excluded.
