Abstract：Aiming at the problem that the seismic behavior of the dual-lintel-column joint of traditional style architecture is poor,a new kind of damping joint was developed by installing viscous dampers on the dual-lintel-column joints in traditional style architecture to enhance the anti-seismic property.Three specimens were tested under harmonic wave dynamic cyclic loading,two of them were joints with viscous damper,and the remaining one had no viscous damper installed for comparison.The results show that the mechanical properties of the joints with viscous damper are significantly better than those of comparing specimen.The hysteretic curve of the joint with viscous damper is plump,the ability of energy dissipation and ductility of the joint with viscous damper are superior to those of the joints without damper,the stiffness and strength degradations are slower than those of comparing specimen,showing that the dual-lintel-column joint in traditional style building with viscous damper has excellent seismic performance.
