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作者简介：窦立军，博士，教授，Email：ljdou63@163.com。参考文献［1］DB 23/T1454—2011 EPS模块混凝土剪力墙结构体系技术规程［S］.［2］祝红梅，梁兴文，邓明科.高强型钢高性能混凝土剪力墙抗震性能研究［J］.建筑结构，2012，42（2）：139-143.［3］金怀印，李文广，许淑芳.带缝空心RC剪力墙结构动力特性试验研究及仿真分析［J］.建筑结构，2009，39（1）：38-40.［4］何国本，陈天宇，王洋.ANSYS土木工程应用实例［M］.3版.北京：中国水利水电出版社，2011.［5］李丽萍.高层短肢剪力墙结构非线性有限元分析及其性能研究［D］.南京：河海大学，2006.
