Taipei 101, formerly known as the Taipei World Financial Center, is a landmark skyscraper located in Xinyi District in Taipei. The building ranked officially as the world’s tallest from 2004 until the opening of the Burj Khalifa in Dubai in 2010. In July 2011, the building was awarded LEED Platinum certification, the highest award in the Leadership in Energy and Environmental Design (LEED) rating system and became the tallest and largest green building in the world. Taipei 101 was designed by C.Y. Lee & partners and constructed primarily by KTRT Joint Venture. The construction was finished in 2004. 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 building was architecturally created as a symbol of the evolution of technology and Asian tradition. 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 adjoining the tower houses hundreds of fashionable stores, restaurants and clubs.
Taipei 101 is owned by the TFCC and managed by the International division of Urban Retail Properties Corporation based in Chicago. The name originally planned for the building, Taipei World Financial Center, until 2003, was derived from the name of the owner. The original name in Chinese was literally, Taipei International Financial Center.
Thornton-Tomasetti Engineers along with Evergreen Consulting Engineering designed a 660-tonne (728-short-ton) 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 87th 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. Two additional tuned mass dampers, each weighing 6 tonnes (7 short tons), are installed at the tip of the spire which help prevent damage to the structure due to strong wind loads.
