（南京工業(yè)大學(xué)土木工程學(xué)院，南京210009）[摘要] 常州凱悅中心12#樓采用現(xiàn)澆鋼筋混凝土部分框支剪力墻結(jié)構(gòu)，總高度175.4m，屬于超限結(jié)構(gòu)，地震響應(yīng)復(fù)雜。采用基于性能的抗震設(shè)計(jì)方法，利用多種分析手段驗(yàn)證不同水準(zhǔn)下結(jié)構(gòu)的抗震性能，包括小震彈性分析、中震彈性分析以及采用基于纖維模型理論的PERFORM-3D軟件對(duì)整體結(jié)構(gòu)進(jìn)行的大震作用下彈塑性時(shí)程分析。建立超限高層建筑結(jié)構(gòu)在不同水準(zhǔn)地震作用下的抗震性能水準(zhǔn)和性能目標(biāo)，進(jìn)而對(duì)結(jié)構(gòu)的地震響應(yīng)及承載性能進(jìn)行評(píng)估。彈性與彈塑性抗震分析結(jié)果表明，常州凱悅中心12#樓能夠滿足《建筑抗震設(shè)計(jì)規(guī)范》提出的各項(xiàng)抗震設(shè)防要求和既定的各項(xiàng)抗震性能指標(biāo)。[關(guān)鍵詞] 超限高層建筑;彈塑性時(shí)程分析;抗震性能中圖分類號(hào)：TU973.2 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：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
