(上海建筑設(shè)計(jì)研究院有限公司，上海200041)[摘要] 曹妃甸新區(qū)市民服務(wù)中心項(xiàng)目屬于超限項(xiàng)目，超限主要表現(xiàn)為大底盤，多塔，連體。結(jié)構(gòu)設(shè)計(jì)采用基于性能的抗震設(shè)計(jì)方法，驗(yàn)證不同水準(zhǔn)下結(jié)構(gòu)及構(gòu)件的抗震性能，包括多遇地震彈性計(jì)算，彈性時(shí)程分析，設(shè)防烈度地震彈性計(jì)算及罕遇地震分析。最后提出了相應(yīng)的設(shè)計(jì)措施，使結(jié)構(gòu)能實(shí)現(xiàn)預(yù)期的性能目標(biāo)。[關(guān)鍵詞] 連體結(jié)構(gòu)；大跨度鋼桁架；抗震性能化設(shè)計(jì)中圖分類號：TU318 文獻(xiàn)標(biāo)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(jié)構(gòu)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
