［摘要］广州某国际金融中心为高度170m的超限高层建筑，采用钢管混凝土柱框架混凝土筒体结构体系。采用SATWE，ETABS进行多遇地震作用和风荷载作用下结构的计算分析，采用SATWE进行弹性时程分析，采用PUSH&EPDA进行大震下的静力弹塑性推覆分析（Pushover）和动力弹塑性时程分析；同时用ETABS分析了楼板在小震、中震及大震作用下的应力。计算结果表明该结构满足规范的各项要求，并采取了一些构造加强措施，可供同类工程参考。

Abstract: An international financial center in Guangzhou is a ultra-limit high-rise building of 170 meters high, with concrete filled steel tubular (CFST) column-concrete corewall structure system. The structure was analyzed by SATWE and ETABS under frequent earthquake and wind load. The elastic time history analysis under frequent earthquake by SATWE, elastic-plastic static analysis (Pushover) and elastic-plastic dynamic analysis (EPDA) under rare earthquake by PUSH&EPDA were carried out. The stress of floor under several earthquake cases was analyzed by ETABS. The results meet requirements of technical codes and some strengthening measures-have also been used to ensure the security of the structure. It can be a reference for other similar projects.

Keywords: ultra-limit high-rise building; concrete filled steel tubular (CFST) column; elasticplastic analysis; time history analysis; strengthening measure
