(艾奕康建筑設計(深圳)有限公司, 深圳 518059)[摘要] 基于性能的結構抗震設計是指根據建筑物的重要性和用途確定其性能目標,根據不同的性能目標提出不同的抗震設防標準,使設計的建筑在未來地震中具備預期的功能。本文采用MIDAS/GEN對喜悅里華庭一棟31層剪力墻結構進行靜力彈塑性分析,計算結果表明,該方法可從層間位移角、塑性鉸分布等方面對結構進行量化評價,并揭示出結構在罕遇地震作用下的薄弱部位,是實現(xiàn)基于性能的抗震設計的有效方法。[關鍵詞] 剪力墻; 靜力彈塑性; MIDAS; Push-over; 基于性能抗震設計中圖分類號:TU973+.23 文獻標識碼:A 文章編號:1002-848X(2013)S2-0387-03作者簡介: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
