Taipei 101, also known as the Taipei Financial Center, is a landmark skyscraper located in Xinyi District, Taipei, Taiwan. The building ranked officially as the world's tallest from 2004 until the opening of the Burj Khalifa in Dubai in 2010. Taipei 101, designed by C.Y. Lee & partners and constructed primarily by KTRT Joint Venture and numerous subcontractors including Samsung C&T received the 2004 Emporis Skyscraper Award and was hailed as one of the Seven New Wonders of the World (Newsweek magazine, 2006) and Seven Wonders of Engineering (Discovery Channel, 2005).The tower has served as an icon of modern Taiwan ever since its opening. Fireworks launched from Taipei 101 feature prominently in international New Year's Eve broadcasts and the structure appears frequently in travel literature and international media.
Taipei 101 comprises 101 floors above ground and 5 floors underground. The name of the tower reflects its floor count. The building was architecturally created as a symbol of the evolution of technology and Asian tradition (see "Symbolism" below.) Its postmodernist approach to style incorporates traditional design elements and gives them modern treatments. The tower is designed to withstand typhoons and earthquakes. A multi-level shopping mall adjoins the tower houses to hundreds of fashionable stores, restaurants and clubs.

Vital Statistics: With a massive 60-foot spire inspired by Twaiwan's native bamboo plant, Taipei 101 Tower is one of the tallest buildings in the world. At 508 meters (1,667 feet) high, the tower and its spire outrank the Petronas Twin Towers in Kuala Lumpur, Malaysia. Taipei Tower has 198,347 m2 (2,336,000 sq. ft.) of office space, 77,033 m2 (796,000 sq. ft.) of retail space, and 83,000 m2 (893,000 sq. ft.) of parking space for more than 1,800 vehicles.
Construction
Taipei 101 is designed to withstand the typhoon winds and earthquake tremors common in its area of the Asia-Pacific. Planners aimed for a structure that could withstand gale winds of 60 m/s (197 ft/s, 216 km/h, 134 mph) and the strongest earthquakes likely to occur in a 2,500 year cycle.
Skyscrapers must be flexible in strong winds yet remain rigid enough to prevent large sideways movement (lateral drift). Flexibility prevents structural damage while resistance ensures comfort for the occupants and protection of glass, curtain walls and other features. Most designs achieve the necessary strength by enlarging critical structural elements such as bracing. The extraordinary height of Taipei 101 combined with the demands of its environment called for additional innovations. The design achieves both strength and flexibility for the tower through the use of high-performance steel construction. Thirty-six columns support Taipei 101, including eight "mega-columns" packed with 10,000-psi concrete. Every eight floors, outrigger trusses connect the columns in the building's core to those on the exterior.
Thornton-Tomasetti Engineers along with Evergreen Consulting Engineering designed a 660 metric tons (728 short tons)steel pendulum that serves as a tuned mass damper, at a cost of NT$132 million (US$4 million).Suspended from the 92nd to the 88th floor, the pendulum sways to offset movements in the building caused by strong gusts. Its sphere, the largest damper sphere in the world, consists of 41 circular steel plates, each with a height of 125 mm (4.92 in) being welded together to form a 5.5 m (18 ft) diameter sphere.[13] Another two tuned mass dampers, each weighing 6 metric tons (7 short tons),sit at the tip of the spire. These prevent damage to the structure due to strong wind loads.
Taipei 101's characteristic blue-green glass curtain walls are double paned and glazed, offer heat and UV protection sufficient to block external heat by 50 percent, and can sustain impacts of 7 metric tons (8 short tons).[9] Recycled water meets 20-30 percent of the building's water needs. Upgrades are currently under way to make Taipei 101 "the world's tallest green building" by LEED standards by summer 2011.
Special Design Features: The design of Taipei 101 borrows heavily from Chinese culture. Both the building’s interior and exterior incorporate the Chinese pagoda form and the shape of bamboo flowers. The lucky number eight, which means blooming or success, is represented by the eight clearly delineated exterior sections of the building.
Observation Decks: Located on floors 89 and 91, the observation decks include the highest restaurant in Taiwan. Two high-speed elevators reach a maximum speed of 1,010 meters/minute (55 ft./second) when traveling to the 89th floor.
