上海真如城市副中心启动区A3地块9号楼及裙房超限高层结构抗震设计

Seismic Structural Design of Complex High-rise Building Named No.9 Building and Podium in A3 Block Which is the Promoter Zone of Zhenru Sub-center in Shanghai

针对上海真如城市副中心启动区A3地块9号楼及其裙房的工程概况,对该项目的结构布置及超限情况进行了介绍,采用SATWE和PMSAP有限元计算程序对该超限结构进行了抗震分析,并找到了结构抗震薄弱部位,结果表明,该超限高层结构的设计均能满足规范要求,剪力墙作为抗震第一道防线,具有较好的延性,框架作为抗震第二道防线,保证大震作用下的结构安全,对于结构薄弱部位,采用构造加强措施确保抗震性能。

This article is going to introduce and analysis the structure layout design of No.9 B-uilding and its annex structure located at Zhenru auxiliary city center, qidong A3 district. Wit-h the assistance of finite element analysis software such as SATWE and PMSAP, the out-of-codes structure’s ability to resist seismic movement has been analyzed; subsequently its weakn-ess part has been identified and located.The results indicate that the structure aspect of this o-ut-of-codes high-rise building fulfills the requirements of current standards implemented by Ch-inese authority. Acting as the first line of defense to resist earthquake, shear-wall possesses n-oticeable properties such as high ductility.As the second line of defense, the frame is able t-o ensure the integrity of the structure. Structure fortification methods should be applied at stru-cture’s weak spot.
