南京某超限高层结构抗震分析

Anti-seismic analysis of a particular super high-rise building in Nanjing

利用SATWE和ETABS两种软件对南京某33层高度为136.0 m超高层结构进行了多遇地震反应谱比较分析、多遇地震下的弹性时程分析、罕遇地震下的动力弹塑性时程分析,并根据不同的抗震性能目标,进行了相应的性能化分析。分析结果表明:两种软件多遇地震反应谱分析结果一致,罕遇地震下最大层间位移角满足规范限值要求,结构主要受力构件损伤较小,能够达到预期的结构抗震性能目标。

The frequent-earthquake response spectrum contrast analysis,elastic time-history analysis under frequent earthquake condition and elastic-plastic dynamic analysis under rare earthquake condition were conducted with SATWE and ETABS on a 33 story super high-rise building,136-meters high,in Nanjing.The corresponding performance-based analysis was applied according to the varied goal of resisting earthquake.It is revealed results of the frequent-earthquake response spectrum contrast analysis from the software were consistent.The maximum story drift angle met the code’s requirement and the damage on main loaded elements was slight.The ability of anticipated anti-seismic structure ability was verified.
