It is and is the 18th tallest building in the world. It contains a shopping mall, offices and the Grand Hyatt Shanghai hotel. Along with the Oriental Pearl Tower, the Shanghai World Financial Center and the Shanghai Tower it is part of the Lujiazui skyline seen from the Bund. It used to be the tallest building in China but its height was surpassed on September 14, 2007, by the Shanghai World Financial Center which is located close by.〔CNN News. "( Shanghai's bristling skyline gets giant new landmark )".〕 The Shanghai Tower, a 121-story building located next to these two buildings, surpassed the height of both these buildings in 2015.〔(【引用サイトリンク】title=The tallest building in China )〕 ==Structure== The building is located on a plot of land near the Lujiazui metro station and was built at an estimated cost of US$530 million. It was designed by the Chicago firm of Skidmore, Owings & Merrill (SOM). 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 (92 if the spire floors are counted) are divided into 16 segments, each of which is 1/8 shorter than the 16-story base. The tower is built around an octagon-shaped concrete shear wall core surrounded by 8 exterior composite supercolumns and 8 exterior steel columns. Three sets of 8 two-story high outrigger trusses connect the columns to the core at six of the floors to provide additional support. The foundations rest on 1,062 high-capacity steel piles driven deep in the ground to compensate for poor upper-strata soil conditions. At the time of construction, these were the longest steel piles ever used for a land-based building. The piles are capped by a 4 m-thick concrete raft underground. The basement's surrounding slurry wall is thick, high and long. It is composed of of reinforced concrete. The building employs an advanced structural engineering system of wind and earthquake engineering which fortify it against typhoon winds of up to 200 km/h (with the top swaying by a maximum of ) and earthquakes of up to 7 on the Richter scale. The steel shafts have shear joints that act as shock absorbers to cushion the lateral forces imposed by winds and quakes. The swimming pool on the 57th floor is also said to act as a passive damper. The exterior curtain wall is made of glass, stainless steel, aluminum, and granite and is criss-crossed by complex latticework cladding made of aluminum alloy pipes. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Jin Mao Tower」の詳細全文を読む スポンサード リンク
