According to the pseudo-static test,compared the damage phenomena, ultimate capacity, ductility and energy dissipation capacity of those walls,and got the hysteresis curve. It indicates that shear walls with large aspect ratio are bending failure which has good seismic behavior and energy dissipation capacity. Shear walls with small aspect ratio are bending-shear failure. The results using ANSYS to simulate the pseudo-static process are consistent to the experiment results. As a new insulating weight-bearing structural system, EPS module has broad prospect in residential building in future, should choose shear walls with large aspect ratio for engineering design and application.Keywords: EPS module; pseudo-static experiment; aspect ratio; hysteresis curve作者簡介:竇立軍,博士,教授,Email:ljdou63@163.com。參考文獻(xiàn)[1]DB 23/T1454—2011 EPS模塊混凝土剪力墻結(jié)構(gòu)體系技術(shù)規(guī)程[S].[2]祝紅梅,梁興文,鄧明科.高強(qiáng)型鋼高性能混凝土剪力墻抗震性能研究[J].建筑結(jié)構(gòu),2012,42(2):139-143.[3]金懷印,李文廣,許淑芳.帶縫空心RC剪力墻結(jié)構(gòu)動力特性試驗(yàn)研究及仿真分析[J].建筑結(jié)構(gòu),2009,39(1):38-40.[4]何國本,陳天宇,王洋.ANSYS土木工程應(yīng)用實(shí)例[M].3版.北京:中國水利水電出版社,2011.[5]李麗萍.高層短肢剪力墻結(jié)構(gòu)非線性有限元分析及其性能研究[D].南京:河海大學(xué),2006.
