（南京工业大学土木工程学院，南京210009）[摘要] 常州凯悦中心12#楼采用现浇钢筋混凝土部分框支剪力墙结构，总高度175.4m，属于超限结构，地震响应复杂。采用基于性能的抗震设计方法，利用多种分析手段验证不同水准下结构的抗震性能，包括小震弹性分析、中震弹性分析以及采用基于纤维模型理论的PERFORM-3D软件对整体结构进行的大震作用下弹塑性时程分析。建立超限高层建筑结构在不同水准地震作用下的抗震性能水准和性能目标，进而对结构的地震响应及承载性能进行评估。弹性与弹塑性抗震分析结果表明，常州凯悦中心12#楼能够满足《建筑抗震设计规范》提出的各项抗震设防要求和既定的各项抗震性能指标。[关键词] 超限高层建筑;弹塑性时程分析;抗震性能中图分类号：TU973.2 文献标识码：A 文章编号：1002-848X(2013)S1-0504-05Seismic performance research of Kaiyue Center in ChangzhouJia Guoqing, Wang Shuguang, Liu Weiqing, Du Dongsheng（College of Civil Engineering, Nanjing University of Technology, Nanjing 210009, China）Abstract: Partial frame-supported shear wall structure is adopted for the 12 tower of Kaiyue Center in Changzhou at a height of 175.4m. This tower is a super high-rise building whose earthquake response is intricate. Design and analysis procedures of the structure, which are based on the performance-based seismic design method, consist of elastic analysis under frequent earthquake, elastic analysis and unyielding analysis of components under moderate earthquake, and elasto-plasticity analysis under rare earthquake carried out using PERFORM-3D. Performance levels and performance goals of tall buildings beyond the code-specification under different earthquake intensities were established. Then evaluate the bearing capacity and earthquake response of components. The analytical results of the elastic and elasto-plasticity shows that the response of 12 tower can meet the requirement of the code for seismic design building of China and the performance goal.Keywords: super high-rise building; elasto-plastic time history analysis; seismic performance
