为了研究开洞口对L形截面短肢剪力墙力学性能的影响，在短肢剪力墙的截面尺寸和配筋率保持不变的情况下，运用ANSYS有限元软件，对不同开洞率的短肢剪力墙的力学性能进行研究，分析短肢剪力墙的承载力和屈服位移。模拟结果表明，短肢剪力墙的承载能力随着短肢剪力墙开洞率的增加而降低，短肢剪力墙腹板底部以及开洞处是试件最薄弱的部位，开洞会降低短肢剪力墙的单调荷载下的力学性能，短肢剪力墙开洞直径不宜过大。

In order to study the effect of the opening hole on mechanical properties of L shaped short pier shear wall, applies ANSYS finite element software to investigate the mechanical properties of short pier shear wall of different opening rates under the unchanged cross-sectional dimensions and reinforcement rates of the wall, and analyzes the bearing capacity and yield displacement. The simulated results show that the bearing capacity decreases with the openings rate increment and the bottom of the web as well as the opening position of the short pier shear wall are the weakest. Opening holes will reduce the mechanical properties of short pier shear walls under monotonic loading, and the opening diameter on short pier shear walls should not be too large.
