摘　　要：为改善装配式剪力墙的抗震性能,文中设计一种型钢-螺栓连接的装配式剪力墙。通过有限元软件ABAQUS建立有限元模型,探究在低周往复荷载下的破坏机理及受力特性。结果表明装配式剪力墙采用型钢连接,其抗震性能与现浇连接方式基本一致,极限承载力提高了24.4%,延性相差1%;轴压比对装配式剪力墙的抗震性能影响较大;文中研究可为型钢连接装配式剪力墙结构的设计提供参考。An assembled shear wall with profile-bolt connection is designed to improve the seismic performance of assembled shear wall,this paper designs an assembled shear wall with profile-bolt connection.A finite element model is established by finite element software ABAQUS to investigate the damage mechanism and force characteristics under low circumferential reciprocating load.The results show that the seismic performance of the assembled shear wall with section steel connection is basically the same as that of the cast-in-place connection,with an increase of 24.4%in the ultimate bearing capacity and a difference of 1%in the ductility;the axial compression ratio has a greater influence on the seismic performance of the assembled shear wall.The results can provide some reference for its application in practical engineering.
