(艾奕康建筑设计（深圳）有限公司， 深圳 518059)[摘要] 基于性能的结构抗震设计是指根据建筑物的重要性和用途确定其性能目标，根据不同的性能目标提出不同的抗震设防标准，使设计的建筑在未来地震中具备预期的功能。本文采用MIDAS/GEN对喜悦里华庭一栋31层剪力墙结构进行静力弹塑性分析，计算结果表明，该方法可从层间位移角、塑性铰分布等方面对结构进行量化评价，并揭示出结构在罕遇地震作用下的薄弱部位，是实现基于性能的抗震设计的有效方法。[关键词] 剪力墙; 静力弹塑性; MIDAS; Push-over; 基于性能抗震设计中图分类号：TU973+.23 文献标识码：A 文章编号：1002-848X(2013)S2-0387-03作者简介：姚文斌，本科，工程师,Email：Wenbin.Yao@aecom.com。Push-over analysis of Xiyueli Huating based on MIDAS/GenYao Wenbin, Liao Xiaoxiong(AECOM Architectural Design (Shenzhen) Co. , Ltd. , Shenzhen 518059, China)Abstract: Performance based seismic design is a method that according to the importance and use of the building, setting its performance goals，then determining different seismic standards from different performance goals，in order to make the building having the desired functionality in a future earthquake. In this paper, the author uses MIDAS/GEN to carry out push-over analysis of a 31-story shear wall structure of Xiyueli Huating. The results show that this method can evaluate the structure from the drift and the distribution of plastic hinges, and can reveal the weak part of the structure in the earthquake, and prove that it’s an effective way to do the performance-based seismic design.Keywords: shear wall; nonlinear static analysis; MIDAS; push-over; performance based seismic design
