[摘要]深圳证交所大楼为一体型复杂的超限高层,底部裙房为大悬臂结构,距地面高度36m。为了评价结构的抗震性能,采用MIDAS和ETABS软件对结构在常遇地震作用下的性能进行分析,采用动力弹塑性时程分析方法对结构在大震作用下的抗震性能进行分析。介绍了计算参数的选取、墙柱的损伤和结构的位移时程。结果表明,结构能够实现“大震不倒”的性能目标,根据结构的薄弱位置,给出了设计建议。

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
