摘   要：利用ABAQUS对竖向钢筋连接方式不同的预制剪力墙进行建模，对比分析其平面外性能。竖向钢筋连接方式分别为双排逐根连接、“梅花形”部分连接及单排连接。结果表明，剪力墙平面外破坏属于脆性破坏，墙身与地梁脱开，有倾覆趋势，但平面外仍具有一定的承载能力和刚度。竖向钢筋连接方式不同对预制剪力墙平面外承载力和刚度均有较大影响，由逐根连接改为部分连接其平面外极限承载力下降约15%，与现浇对比差距较大，刚度退化速度也大于现浇。
Abstract: The ABAQUS was used to model the prefabricated shear walls with different vertical reinforcement connections, and the out-of-plane performance was compared and analyzed. The vertical reinforcement connection modes were double row root-to-root connection, "plum-shaped" partial connection and single row connection. The results show that the out-of-plane damage of the shear wall is brittle failure，the wall and the ground beam are separated, but there is still a certain bearing capacity and stiffness outside the plane. Different connection modes of vertical reinforcement have a great influence on out-of-plane bearing capacity and stiffness of the prefabricated shear wall. From the root-to-root connection to the partial connection, the out-of-plane ultimate bearing capacity is reduced by about 15%，the rate of stiffness degradation is also greater than that of the cast-in-place shear wall.
