Abstract

Abstract

In order to solve the problem of large amount of spot welding on existing wall-beam joints of steel tube bundle shear wall structure, a new type of anchoring prefabricated wall-beam joint for steel tube bundle shear wall structure was preposed. The failure modes, internal force distribution and the influence of plate thickness, anchorage length, and concrete strength grade on the seismic performance of the joint were studied by using the finite element software ABAQUS. The results showed that the hysteretic curve of the joint was full, showing good ductility and energy dissipation capacity. With the increase of the end plate thickness, the bearing capacity and seismic performance of the joint did not change significantly. With the increase of the anchorage length, the seismic performance of the joint was enhanced, and the bearing capacity increased significantly. However, when the anchorage length was 800 mm, the seismic performance and bearing capacity of the joint did not change significantly. With the improvement of concrete strength grade, the bearing capacity of the joint was less affected and gradually transformed from the local compressive bearing capacity of the concrete of the stud tail to the shear bearing capacity of the studs.
