[摘要]甘肃张掖大剧院结构具有体型复杂、内部空旷、跨度大等特点。针对结构超限情况,设计中采取相应的抗震设防措施,设定合适的抗震性能目标。通过对结构进行小震、中震和大震作用下的性能分析,验算各构件在地震作用下的抗震性能,实现对结构的性能化设计。结果表明,小震作用下,结构各构件均处于弹性状态;中震作用下,结构重要的竖向构件保持弹性,耗能构件部分屈服;大震作用下,结构各构件均能满足预定的抗震性能目标。[关键词]复杂体型; 性能化设计; 性能目标; 抗震措施中图分类号:TU318 文献标识码:A 文章编号:1002-848X(2015)15-0036-05
Performance-based seismic design on Zhangye Theatre in Gansu ProvinceZhou Bin, Wang Qiwen, Yang Wanghua, Liu Guoyin, Lu Yu, Li Shujuan(Shenzhen General Institute of Architectural Design and Research Co., Ltd., Shenzhen 518031, China)Abstract:Zhangye Theatre has characterizes of complex shape, hollow inside and large span. Appropriate seismic measures were adopted as well as seismic performance objectives in response to the out-of-code aspects of the structure. Through performance analyses of the structure under the frequent, fortification and rare earthquake, seismic performance of each component under seismic conditions was checked, and performance-based seismic design was realized. The results show that the structure maintains elastic under the frequent earthquake. The important vertical components maintain flexible while parts of energy dissipation components yield under the fortification earthquake. All components can satisfy performance-based seismic objective under the rare earthquake.Keywords:complex shape; performance-based design; performance objective; seismic measure
