And the outer frames on the east and west sides adopt transfer truss structure in the scope of podium. The cantilever podium is located at storeys 7 to 10 of the tower and has a maximum cantilever of 37m, which is supported by steel trusses. The building is out-of-height and out-of-code, which is influenced greatly by seismic action and wind loading. Based on seismic performance targets under different performance levels, structural design scheme and overall performance were studied considering wind loading data from wind tunnel test. Two analysis programs were used to calculate and compare in elastic analysis, and non-linear time-history analysis of the tower was carried out. The results show that the overall structural performance meets relevant requirements of Chinese design codes. The structure is safe and component design is generally governed by wind loading or gravity loading. The structural seismic performance under the rare earthquake meets the performance objective of ″not collapse under the rare earthquake″.Keywords: composite frame; transfer truss; cantilever; member design; rare earthquake作者簡介：樸才思，劍橋大學(xué)碩士，英國特許工程師，英國土木工程學(xué)會、英國結(jié)構(gòu)工程師學(xué)會會員，Email:chas.pope@arup.com。參考文獻(xiàn)［1］GB 50011—2001 建筑抗震設(shè)計規(guī)范［S］.北京：中國建筑工業(yè)出版社，2001.［2］JGJ 3—2002 高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程［S］.北京：中國建筑工業(yè)出版社，2002.［3］甄圣威，汪洋. 超高層結(jié)構(gòu)彈塑性模擬中若干問題的討論［J］.建筑結(jié)構(gòu)，2013，43(S1)：546-551.
