【摘要】 结合现行国家规范与规程,采用弹塑性时程分析方法,对招商银行上海大厦连桥部分这一连体结构进行抗震分析,探讨连体结构在罕遇地震作用下的动力响应。对剪力墙进行等效化处理,重点讨论了在罕遇地震作用下结构的基底剪力及剪重比、层间位移角以及结构整体塑性发展的过程。计算结果显示,与连廊桁架相连的部分墙体和筒体根部的墙体为结构的薄弱部位,塑性发展程度大,设计时应引起重视。结构最大层间位移角为1/192,满足规范相关要求。更多还原

【Abstract】 Combined with present national codes and regulations,elasto-plastic time history analysis with connected bridge of China merchants bank tower shanghai building was carried out.The dynamic response of this connected structure under rare earthquake had been discussed.With the equivalence shear wall,the base shear force and shear-weight ratio as well as the inter-story drift and plastic development process of the whole structure had been studied.The analysis results show that,the wall which connect with gallery and on the bottom of tube shell wall are easily to be destroyed.It is necessary to pay attention to this phenomenon.The maximum inter-story drift of the structure is 1/192,it is in good requirement with the code for seismic.更多还原
