摘　　要：分析了两榀钢筋混凝土短肢剪力墙试件在低周反复水平荷载作用下的破坏形态和刚度衰减,对其顶点弹性水平位移和承载力进行了理论分析,并与试验结果对照验证理论分析的正确性。研究表明,短肢剪力墙的受力性能与联肢墙相同,整体性系数α愈大,其侧向刚度和承载力愈大,但延性及耗能性能差。This paper analyzes the destroy modality and the stiffness failing of 2 R. C. short-pier shear walls specimens under laterally reversed low cyclic loading. The elastic top horizontal displacement and the bearing capacity are also theoretically analyzed and compared with results obtained in experiments to validate the correctness of the theoretical analysis. The research results show that the mechanic properties of short-pier shear walls are the same as the combined shear waUs and if the integrative coefficient a is increasing, the lateral stiffness and the bearing capacity will be getting up but the ductility and energy dissipation will be going down.
