Shanghai Tower

This article is incomplete. The Shanghai Tower (Chinese: 上海中心大厦; pinyin: Shànghǎi Zhōngxīn Dàshà;  Shanghainese : Zånhe Tsonshin Dasa; literally meaning "Shanghai Centre Tower") is a 632-metre (2,073 ft) and 128-story megatall skyscraper in Pudong, Shanghai.

Design
The tower takes the form of nine cylindrical buildings stacked atop each other, totaling 127 floors, all enclosed by the inner layer of the glass façade. Between that and the outer layer, which twists as it rises, nine indoor zones provide public space for visitors. Each of these nine areas has its own atrium, featuring gardens, cafés, restaurants and retail space, and providing panoramic views of the city. The design of the tower's glass façade, which completes a 120° twist as it rises, is intended to reduce wind loads on the building by 24%. This reduced the amount of construction materials needed; the Shanghai Tower used 25% less structural steel than a conventional design of a similar height. Consequently, the building's constructors saved an estimated CN¥385.9 million (US$58 million) in material costs.
