（CCDI悉地國際，深圳518048）[摘要] 青島卓越世紀中心1號塔樓是存在多項超限情況的超高層框架-核心筒結構。首先確定了抗震性能目標及設計方法，然后采用Midas Building有限元軟件對結構在大震作用下的抗震性能進行了分析，基于結構整體及構件層面，總結了其在大震作用下的性能水準，發(fā)現(xiàn)其薄弱部位，為有針對性地采取抗震措施提供參考。[關鍵詞] 抗震性能;大震;動力彈塑性;性能水準中圖分類號：TU973.2 文獻標識碼：A 文章編號：1002-848X(2013)S1-0552-05Elastic-plastic time history analysis on the super high-rise building structure ofQingdao Excellence Century CentreLiu Yunlang, Liu Wenqing, Yang Feng, Li Jianwei, Shi Yongmang(CCDI GROUP, Shenzhen 518048, China)Abstract: There are some cases out of code about a super high-rise building, No.1 tower of Qingdao Excellence Century Centre, which is a frame-core wall structure. Objectives and design methods of seismic performance were determined, and then the performance-based seismic analysis of the structure was conducted under rare earthquake with finite element software Midas Building. Performance level of the structure and elements was summarized under rare earthquake, and the weak spots of the structure were found out. The analysis results can be used for the seismic design measures.Keywords: seismic performance; rare earthquake; elastic-plastic; performance level
