Abstract：To investigate the influence of the filled concrete on the seismic behavior of K-type square steel tubular joint, the low cycle repeated load test is carried out for one K-type square steel tubular joint (empty tubular joint) and one K-type square steel tubular joint of the main tube filled with concrete.According to the experimental data, the failure mode, hysteretic behavior, bearing capacity, ductility, stiffness and energy dissipation capacity of the joints are analyzed.The results show that the bearing capacity, ductility and stiffness of the joint are improved after the K-type square steel tubular joint of the main tube is filled with the concrete, but the energy dissipation capacity decreases.
