摘　　要：为了研究带有预制混凝土(PC)填充墙的联肢剪力墙结构受力性能,对带有PC填充墙的联肢剪力墙在水平荷载作用下的受力性能进行了数值模拟分析,考察了结构在不同连接方式和轴压比条件下的破坏形态、承载能力、刚度和延性等性能。结果表明:PC填充墙可提高联肢剪力墙结构的承载力和抗侧刚度;当轴压比为0.3时,刚性连接下结构的承载力和刚度比无填充墙时分别增大43.1%、125.47%,柔性连接下结构的承载力和刚度比无填充墙时分别增大13.69%、88.69%,但刚性连接下的延性比无填充墙和柔性连接下的分别减少17.57%,40.73%;随着轴压比的增大,结构承载力增大,刚度提高,但延性性能降低;PC填充墙使得联肢剪力墙结构的破坏程度降低,在地震作用下,可有效的保护主体结构。A numerical simulation analysis is conducted to evaluate the mechanical performance of the coupled shear wall with precast concrete(PC)infill wall.The destruction,bearing capacity,stiffness and ductility are evaluated with different connection modes and axial compression ratios.The result shows that the existence of PC infill wall can increase the bearing capacity and lateral stiffness.With the increasing of axial compression ratios,the bearing capacity and the stiffness of the structure is increased,but the ductility performance becomes worse.When the axial compression ratio is 0.3,the bearing capacity and stiffness of the rigid connection increase by 43.1%and 125.47%compared with that of the non-infilled wall,and the flexible connection increases by 13.69%and 88.69%compared with the non.However,the ductility of the rigid connection is 17.57%and 40.73%lower than that of non-filled walls and flexible connections.At the same time,the existence of PC infill wall reduces the damage of structure and can be used as the first line of defense for structural damage.
