［摘要］甘肅張掖大劇院結(jié)構(gòu)具有體型復(fù)雜、內(nèi)部空曠、跨度大等特點。針對結(jié)構(gòu)超限情況，設(shè)計中采取相應(yīng)的抗震設(shè)防措施，設(shè)定合適的抗震性能目標(biāo)。通過對結(jié)構(gòu)進(jìn)行小震、中震和大震作用下的性能分析，驗算各構(gòu)件在地震作用下的抗震性能，實現(xiàn)對結(jié)構(gòu)的性能化設(shè)計。結(jié)果表明，小震作用下，結(jié)構(gòu)各構(gòu)件均處于彈性狀態(tài)；中震作用下，結(jié)構(gòu)重要的豎向構(gòu)件保持彈性，耗能構(gòu)件部分屈服；大震作用下，結(jié)構(gòu)各構(gòu)件均能滿足預(yù)定的抗震性能目標(biāo)。［關(guān)鍵詞］復(fù)雜體型; 性能化設(shè)計; 性能目標(biāo); 抗震措施中圖分類號：TU318 文獻(xiàn)標(biāo)識碼：A 文章編號：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
