FEM Analyses on Hysteretic Behavior of Steel Coupling Beam-column Connections with Steel Boundary Elements Welded in Hybrid Coupled Shear Wall Systems

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.
