摘　　要：通过利用ABAQUS有限元软件对型钢边缘构件-钢连梁焊接型混合连肢墙(HCW)节点滞回性能进行有限元分析,研究混合连肢墙在低周循环荷载作用下的抗震性能,并将有限元计算结果与试验结果进行了对比,吻合情况较好。同时,试验研究与有限元分析结果均表明:节点滞回曲线饱满,且延性系数及极限承载力较高,表明节点具有良好的抗震性能。The finite element analyses on hysteretic behavior of steel coupling beam-column connections with steel boundary elements welded in hybrid coupled shear wall system were performed by using the FEM software ABAQUS for numerical simulation,so as to obtain the seismic performance of hybrid coupled shear wall system under low cyclic loading.The results of the finite element analyses agree quite well with experimental results.Meanwhile,the finite element analysis results and experimental results all indicate that the hysteretic curve of connections in hybrid coupled wall is full,and the ductility factor and ultimate bearing capacity are high,which shows that this kind of connection has high seismic performance,and is suitable for using in the high-rise buildings in high-intensity earthquake areas.
