摘　　要：楼高44.82m的某文化艺术中心(PC板方案)为复杂大跨度建筑,由3个剪力墙圆筒组成竖向传力结构体系,圆筒之间采用5道和6道桁架相连,最大跨度分别约为70m和90m,结构3层设置转换层,外皮是由加预应力PC板组成一个空间的网壳受力体系。本文采用ABAQUS软件对该结构进行弹塑性时程分析,根据结构的顶点位移、基底剪力、钢材塑性应变和壳单元损伤等计算结果,分析在罕遇地震下结构的抗震性能,为抗震设计提供依据。A Culture and Arts Centre is a complicated long-span structure with 44.82m height,3 shear-wall concrete tubes composes vertical force transmission structure system.Five or six trusses are used to be the connection among the tubes.The maximum spans of trusses respectively are about 70m and 90m.In 3rd floor,it's set the transfer floor.Shell is composed of a space prestressed PC slab system.ABAQUS software is adopted to execute nonlinear time-history analysis.Based on the vertex displacement of the structure,base shear,plastic strain of steel and damage of shear element,the seismic performance is analyzed under strong earthquake,which can be referred to the seismic design.
