The world tallest building

0aipei 101



































Taipei 101 is a 101-floor landmark skyscraper located in Taipei, Taiwan. The building, designed by C.Y. Lee & Partners and constructed by KTRT Joint Venture, is the world's tallest completed skyscraper. Taipei 101 received the Emporis Skyscraper Award in 2004. It has been hailed as one of the Seven New Wonders of the World and Seven Wonders of Engineering . The building serves as an icon of Taipei and Taiwan as a whole. Fireworks launched from the tower feature prominently in international New Year's Eve broadcasts, and the landmark appears frequently in films, television shows, print publications, anime media, games, and other elements of popular culture.
Taipei 101 was the first building in the world to break the half-kilometer mark in height. It was the first "world's tallest building" to be constructed in the new millennium.
Taipei 101 displaced the Petronas Towers in Kuala Lumpur, Malaysia, as the tallest building in the world by 57.2 metres (188 ft). It also displaced the 85-story, 347.5 metres (1,140 ft) Tuntex Sky Tower in Kaohsiung as the tallest building in Taiwan and the 51-story, 244.2 metres (801 ft) Shin Kong Life Tower as the tallest building in Taipei.
The Burj Dubai (United Arab Emirates) overtook Taipei 101 in height upon completion of its 141st floor on 2007-07-21. The Burj Dubai is expected to hold a number of world records by the time it opens in mid-2009. Taipei 101 retains its official title until the Burj Dubai is completed, however, as the Council on Tall Buildings and Urban Habitat does not officially recognize a structure as a "building" for record purposes until it is functional--that is, until it is completed and can be occupied.
Various sources, including the building's owners, give the height of Taipei 101 as 508.0 metres (1,667 ft), roof height and top floor height as 448.0 metres (1,470 ft) and 438.0 metres (1,437 ft). This lower figure is derived by measuring from the top of a 1.2 metres (4 ft) platform at the base. CTBUH standards, though, include the height of the platform in calculating the overall height, as it represents part of the man-made structure and is above the level of the surrounding pavement.

The Petronas Twin Towers

























The Petronas Twin Towers (also known as the Petronas Towers or Twin Towers), in Kuala Lumpur, Malaysia are the world's tallest twin buildings. They were the world's tallest buildings from 1998 to 2004 if measured from the level of the main entrance to the structural top, the original height reference used by the US-based Council on Tall Buildings and Urban Habitat from 1969 (three additional height categories were introduced as the tower neared completion in 1996).
Burj Al Arab























The Burj Al Arab "Tower of the Arabs" is a luxury hotel in Dubai, United Arab Emirates managed by the Jumeirah Group and built by Said Khalil. It was designed by Tom Wright of WS Atkins PLC. At 321 metres (1,053 ft), it is the tallest building used exclusively as a hotel. However, the Rose Tower, also in Dubai, which has already topped Burj Al Arab's height, will take away this title upon its completion in 2007. The Burj Al Arab stands on an artificial island 280 metres (919 ft) out from Jumeirah beach, and is connected to the mainland by a private curving bridge. It is an iconic structure, designed to symbolize Dubai's urban transformation and to mimic the billowing sail of a boat.

Jin Mao Building


























The building is located on a 24 000 m² plot of land near the Lujiazui metro station. It was designed by the Chicago office of Skidmore, Owings & Merrill. Its postmodern form, whose complexity rises as it ascends, draws on traditional Chinese architecture such as the tiered pagoda, gently stepping back to create a rhythmic pattern as it rises.
Like the Petronas Towers in Malaysia, the building's proportions revolve around 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 1/8th shorter than the 16-story base.
