Under the national strategy of developing vigorously the prefabricated structure, to study the prefabrication and assembly of steel reinforced concrete shear walls, but the connection performance of the precast steel frame is the key to determine whether the prefabricated structure can be carried out. To the steel joint with grouting bolt sleeve, based on the ABAQUS finite element analysis software, the anchorage length, the thickness of sleeve wall and the bolt diameter are used as the analysis parameters, and it is to be analyzed for the influence trend of the model parameters on the joint performance. The results show that the anchorage length, the thickness of sleeve wall and the bolt diameter all have a positive influence on the tensile bearing capacity, in the meantime, the rational combination can optimize the failure state and improve the tensile bearing capacity of the joints.
