(艾奕康建筑設(shè)計(jì)（深圳）有限公司， 深圳 518059)[摘要] 基于性能的結(jié)構(gòu)抗震設(shè)計(jì)是指根據(jù)建筑物的重要性和用途確定其性能目標(biāo)，根據(jù)不同的性能目標(biāo)提出不同的抗震設(shè)防標(biāo)準(zhǔn)，使設(shè)計(jì)的建筑在未來(lái)地震中具備預(yù)期的功能。本文采用MIDAS/GEN對(duì)喜悅里華庭一棟31層剪力墻結(jié)構(gòu)進(jìn)行靜力彈塑性分析，計(jì)算結(jié)果表明，該方法可從層間位移角、塑性鉸分布等方面對(duì)結(jié)構(gòu)進(jìn)行量化評(píng)價(jià)，并揭示出結(jié)構(gòu)在罕遇地震作用下的薄弱部位，是實(shí)現(xiàn)基于性能的抗震設(shè)計(jì)的有效方法。[關(guān)鍵詞] 剪力墻; 靜力彈塑性; MIDAS; Push-over; 基于性能抗震設(shè)計(jì)中圖分類(lèi)號(hào)：TU973+.23 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2013)S2-0387-03作者簡(jiǎn)介：姚文斌，本科，工程師,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
