Analysis of Seismic Performance of Shenzhen Stock Exchange Square Chen Zhiqiang, Zhang Tao, Hu Shouying, Mao Renxing(China Electronics Engineering Design Institute, Shenzhen Electronics Design Institute Co., Ltd., Shenzhen, 518031)
Abstract:Shenzhen Stock Exchange Square is an ultra-limit high-rise structure. The three-story raised cantilevering podium is 36 meters above ground level. To estimate the seismic performance of the structure, the analysis with MIDAS and ETABS
software under frequent earthquake and dynamic elastic-plastic time-history analysis method under rare earthquake are carried
out. It is shown that the requirement of no collapse with rare earthquake can be achieved. Meanwhile, the weakness of the
structure is found, and some advices are presented.
Keywords:ultra-limit high-rise building; ABAQUS; seismic performance; dynamic elasticplastic time-history analysis;
concrete damaged plastic model
