摘要: 预埋钢板-螺栓连接是一种新型装配式混凝土剪力墙竖向拼缝连接形式。为研究该类型连接混凝土剪力墙的抗震性能，对两个试件进行拟静力对比试验（含1个箍筋插销连接形式），并采用ABAQUS软件对试验进行了模拟，研究对比两种类型竖缝连接剪力墙的承载力、刚度、延性和耗能能力等指标。结果表明：两种竖缝连接形式的剪力墙受力性能良好，采用预埋钢板-螺栓竖缝连接的剪力墙承载能力、刚度、耗能能力略小，延性略大于采用箍筋插销竖缝连接形式的剪力墙；数值模拟结果与试验结果基本吻合。Abstract: The connection of embedded steel plate and bolt is a new type of vertical connection for prefabricated concrete shear wall. In order to study the seismic behavior, quasi-static test was conducted on two shear walls with vertical connection and stirrup bolted connection respectively, and the test was simulated by using the ABAQUS software. The indexes for the two types of shear walls, including the bearing capacity, stiffness, ductility and energy consumption, were analyzed and compared. The results showed that the two types of shear walls both had good mechanical properties. The shear wall with vertical connections of embedded steel plate and bolt had a slightly smaller bearing capacity, stiffness and energy consumption capacity, and a slightly larger ductility compared with the shear wall with stirrup bolted connection. In general, the numerical simulation results could agree well with the test results.
