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。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.
