摘　　要：基于冷挤压套筒连接装配式剪力墙的抗震性能试验结果,采用有限元软件ABAQUS建立非线性有限元模型。对加载全过程中装配式剪力墙的力学性能进行分析,有限元模拟结果与试验结果吻合较好。在此基础上,分析了影响剪力墙力学性能的主要因素,包括墙体剪跨比、轴压比、边缘构件纵筋配筋率等。结果表明:随着轴压比提高,剪力墙极限承载力提高,延性降低;随着剪跨比减小,延性降低;随着边缘构件纵筋配筋率提高,极限承载力略有提高,剪力墙的延性降低。Base on the experimental study on seismic behavior of assembled shear walls with reinforcement connected by pressed steel sleeve,the finite element analysis software ABAQUS was performed to set up a nonlinear finite element analysis(FEA)of new type of as‐sembled shear wall.Mechanical properties of the shear wall were analyzed by simulating the loading process.The result of the finite element analysis was matched with the experiment.Based on the proposed model,main factors influencing mechanical properties of the structure were analyzed including shear span ratio,axial compression ratio and the longitudinal reinforcement ratio of the boundary element.The FEA results shows that with the increase of axial compression ratio,the ultimate bearing capacity of shear wall increases and the ductility decreas‐es;with the decrease of shear-span ratio,the ductility decreases;with the increase of longitudinal reinforcement ratio of edge members,the ultimate bearing capacity increases slightly and the ductility of shear wall decreases.
