Abstract: In order to promote the development of low-rise prefabricated light steel concrete building in rural residential buildings, the prefabricated sleeve joint, which is suitable for beam-column connection, is put forward to overcome the problems, such as difficult connection, inconvenient assembly and poor seismic performance of light steel concrete frame joints. Through the numerical simulation of finite element software ABAQUS, the failure characteristics, hysteretic curve, skeleton curve, stiffness degradation and ductility of joints with different structural forms were analyzed. The effects of axial compression ratio, angle steel thickness and sleeve thickness on its seismic performance are studied. The results show that the seismic performance of joints with different structural forms is quite different. Specifically; the welded joints exhibit high bearing capacity but poor ductility, the hinged joints have low bearing capacity but high ductility; the angle steel joints show good bearing capacity, high ductility coefficient and convenient assembly. The axial compression ratio has little effect on the seismic performance of angle steel joints; The thickness of angle steel and sleeve are two important parameters affecting the seismic performance of angle steel joints. When the thickness of angle steel is between 4 mm and 6 mm and the thickness of sleeve is 6mm, the seismic performance of joints is the best.
