(上海建筑设计研究院有限公司，上海200041)[摘要] 曹妃甸新区市民服务中心项目属于超限项目，超限主要表现为大底盘，多塔，连体。结构设计采用基于性能的抗震设计方法，验证不同水准下结构及构件的抗震性能，包括多遇地震弹性计算，弹性时程分析，设防烈度地震弹性计算及罕遇地震分析。最后提出了相应的设计措施，使结构能实现预期的性能目标。[关键词] 连体结构；大跨度钢桁架；抗震性能化设计中图分类号：TU318 文献标识码：A 文章编号：1002-848X(2013)S1-1107-04作者简介：顾辉，硕士，一级注册结构工程师，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
