Abstract: Steel reinforced concrete structure has many advantages, such as high bearing capacity, good ductility in earthquake and controllable cracks. In recent years, it has been widely studied and applied in building structures. However, traditional steel reinforced concrete has the defects that reinforcement will weaken the bearing capacity of the steel during to penetrating the inner steel, and make the process of construction complex. As the tallest building in Ningxia Hui Autonomous Region, Yinchuan Greenland Center adopts steel reinforced concrete structure. A large number of stirrups need to penetrate the section steel at the beam column joints, which increases the processing capacity of the steel structure, and it is difficult to put the stirrups in place. A construction method of reinforcement without penetrating stirrup is proposed to solve the problem in construction according to the actural situation of the project. In view of this background, two kinds of steel reinforced concrete beam column joints model based on the completed tests was analyzed by using ABAQUS platform. The bearing capacity difference between the improved process and the prototypical process is studied after verification. On the basis of experimental verification of the numerical model, the feasibility of stirrup reinforced joint construction measures was analyzed, and the bearing capacity difference between the improved process and the prototypical process was investigated. In order to explore the influence of different design parameters on the bearing capacity of improved process, this paper analyzed the influence of parameters based on the numerical model of stirrup reinforced joint specimens, and investigated the influence of axial compression ratio, steel content of section steel, and reinforcement ratio of longitudinal reinforcement in column on the skeleton curve of stirrup reinforced joint.The results show that the numerical model can properly simulate the peak bearing capacity, skeleton curve and failure mode of specimens under constant axial pressure and horizontal displacement. The deformation capacity, failure mode and ultimate bearing capacity of the two processes are basically the same, which is consistent with the experimental phenomenon, indicating that the stirrup reinforced type can meet the requirements of structural bearing capacity and failure mode. The improved process therefore can be used to replace prototypical process where the process is complicated. The results of parameter analysis show that with the increase of axial compression ratio, the peak load of skeleton curve remains unchanged, and the ductility of joint test decreases gradually. With the increase of steel ratio of steel reinforced concrete, the bearing capacity of members has a certain range of improvement, and the steel ratio has little effect on the ductility of members with improved construction method. The ratio of main reinforcement has a great influence on the skeleton curve of stirrup reinforced joints, and the peak bearing capacity increases significantly with the increase of the ratio of main reinforcement.
