(上海建筑設計研究院有限公司，上海200041)[摘要] 曹妃甸新區(qū)市民服務中心項目屬于超限項目，超限主要表現為大底盤，多塔，連體。結構設計采用基于性能的抗震設計方法，驗證不同水準下結構及構件的抗震性能，包括多遇地震彈性計算，彈性時程分析，設防烈度地震彈性計算及罕遇地震分析。最后提出了相應的設計措施，使結構能實現預期的性能目標。[關鍵詞] 連體結構；大跨度鋼桁架；抗震性能化設計中圖分類號：TU318 文獻標識碼：A 文章編號：1002-848X(2013)S1-1107-04作者簡介：顧輝，碩士，一級注冊結構工程師，Email:guhui@siadr.com.cn。Seismic design of the citizen service center of CaofeidianGu Hui(Shanghai Institute of Architectural Design &Research Co., Ltd., Shanghai 200041,Abstract: The citizen service center of Caofeidian is an ultra-limit structure (mainly for the multi-tower structure with base block, conjoined structure). Performance based seismic design was used. Structure and component performance were verified under different levers, including elastic analysis under frequent earthquake, elastic time history analysis, elastic analysis under precautionary intensity earthquake, analysis of rare earthquake. Series of relevant were suggested to make sure the performance object can be well realized.Keywords: conjoined structure; large-span steel truss; seismic performance design
