[摘要]揚(yáng)州東方國際大酒店為高度280m的超高層建筑,采用鋼管混凝土框架柱鋼筋混凝土剪力墻核心筒的混合結(jié)構(gòu)體系,采用SATWE進(jìn)行彈性時程分析,采用PUSH&EPDA進(jìn)行大震下的推覆分析和動力彈塑性時程分析,同時用MIDAS/Building分析關(guān)鍵部位在中震作用下的拉應(yīng)力,用MIDAS/FEA對關(guān)鍵節(jié)點(diǎn)進(jìn)行了中震、大震下的應(yīng)力分析。通過分析得出結(jié)構(gòu)能滿足抗震性能設(shè)計的要求,并采取了一些有效的構(gòu)造加強(qiáng)措施,可供同類工程參考。

Abstract:Yangzhou East International Hotel is a super highrise building(height is 280m)with concrete filled steel tubular columnconcrete core wall structure system. 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 tensile stress of the key parts under medium earthquake was analyzed by MIDAS Building. The stress of key points under medium and rare earthquake was analyzed by MIDAS/FEA. The results show that the structure can meet the requirement of performance\|based seismic design. Some strengthening measures were used to ensure the security of the structure. It can be a reference for other similar projects.
Keywords:super highrise building; concrete filled steel tubular column; time history analysis; elasticplastic analysis; performance\|based seismic design
