趙楠 （北京市建筑設計研究院，北京 100045）［摘要］結(jié)合中國科學技術(shù)館新館的工程特點，對該復雜結(jié)構(gòu)設定抗震性能目標，并針對性能目標提出抗震措施及抗震構(gòu)造措施。考慮結(jié)構(gòu)材料的非線性，采用動力非線性分析方法，分析框架-剪力墻結(jié)構(gòu)在地震作用下的動力響應，并對關(guān)鍵部位進行罕遇地震下承載力及耗能專項分析。結(jié)果表明，結(jié)構(gòu)在罕遇地震下滿足規(guī)范要求，關(guān)鍵部位可以實現(xiàn)罕遇地震下不屈服的要求，結(jié)構(gòu)是安全可靠的。［關(guān)鍵詞］超限結(jié)構(gòu)；塑性鉸；耗能能力；非線性分析中圖分類號：TU375文獻標識碼：A文章編號：1002-848X(2012)07-0041-04Performance based design of new China Science and Technology MuseumZhao Nan (Beijing Institute of Architectural Design, Beijing 100045, China)Abstract: According to the characteristics of new China Science and Technology Museum, the goal of seismic design was proposed for the complicated structure. Dynamic nonlinear analysis was adopted considering the nonlinear property of materials. Dynamic response of the frame-shear wall structure under earthquake was carried out, and the bearing capacity and energy dissipation capacity of key parts under rare earthquake were analyzed. The results show that the structure can satisfy the code requirements, the key parts do not yield under rare earthquake, and the structure is safe and reliable.Keywords: out-codes structure; plastic hinge; energy dissipation capacity; nonlinear analysis作者簡介：趙楠，碩士，高級工程師，一級注冊結(jié)構(gòu)工程師， Email：biad1s1@126.com。參考文獻［1］戴國瑩. 建筑結(jié)構(gòu)基于性能要求的抗震措施初探［J］.建筑結(jié)構(gòu), 2000, 30(10): 60-62.［2］李婷，趙楠. 新中國科學技術(shù)館復雜體型鋼-混凝土混合結(jié)構(gòu)的非線性動力彈塑性分析［J］.建筑結(jié)構(gòu), 2009, 39(12): 121-123.［3］樊健生，陶慕軒，聶建國,等. 鋼骨混凝土柱-鋼桁梁組合節(jié)點抗震性能試驗研究［J］.建筑結(jié)構(gòu)學報, 2010, 31(2): 1-10.［4］趙楠. 克拉瑪依科博館傾斜結(jié)構(gòu)抗震設計［J］.地震工程與工程振動, 2011, 31(2): 111-117.［5］趙楠，馬凱，李婷,等. 大底盤多塔高層隔震結(jié)構(gòu)的地震響應［J］.土木工程學報, 2010, 43(S1): 255-258.
