Abstract：Four beam-column joint specimens with viscous dampers and two joint specimens without viscous dampers in traditional-style buildings were tested and compared under dynamic cyclic loading, so that the load-displacement hysteretic loops could be obtained, and the ductility and energy dissipation of the joints could be analyzed. The results show that the hysteretic loops are plump, and the ductility and energy dissipation performances of the joints are good. Based on the experimental results, ABAQUS was employed to build the 3D nonlinear finite element models for analyzing the mechanical properties of the structure. Comparisons disclose that the finite element analysis results agree with the experimental results very well. Furthermore, parametric analysis of the structure was carried out based on the theoretical analysis. The analysis parameters include the axial compression ratio, concrete strength, yield strength of square steel tube and key parameters of damper. The results show that with the increases of the concrete strength, yield strength of square steel tube and damping coefficient, the load-bearing capacity of the structure may increase; with the increase of axial compression ratio and concrete strength, the load-bearing capacity may increase, but the ductility may gradually decrease; with the increase of yield strength of square steel tube, the ductility of the specimens may increase; with the increase of damping exponent, the load-bearing capacity and ductility of the specimens exhibit the characteristics of increasing first and decreasing later, indicating that to improve the seismic performances of beam-column joint in traditional-style buildings with viscous damper, the performance parameters of the viscous damper shall be appropriately selected.
