Abstract: In order to avoid the interaction between flange cover plates and floor, a kind of earthquake-resilient ductility-reinforced prefabricated opening-web steel channel beam-column joint based on the concept of damage control and buckling-restrain was proposed in the paper. Inner flange cover plates and U-shaped web connecting plates were used to connect the cantilever beam and the opening-web steel channel beam. The flange of the cantilever beam was strengthened and the flange cover plates were weakened like dog bone, so the plastic hinge was transferred to the flange cover plates effectively. A total of four examples with different parameters were calculated by finite element method. The influence of the parameters such as the thickness of the flange cover plates, the width of the dog bone weakening section and the number of connecting bolts on the mechanical properties of the joints was mainly studied. By analyzing the load-displacement curves, stress nephogram of joints, stress distribution of components and bolt tension curves obtained by finite element numerical simulation, the paper demonstrated that by setting the relevant parameters reasonably, the earthquake-resilient ductility-reinforced prefabricated opening-web steel channel beam-column joint had good bearing capacity and plastic rotation capacity, and could transfer the plastic hinge outward to the replaceable inner flange cover plates, meeting the design expectation that the joint function could be restored by replacing the local components after the earthquake. U-shaped web connecting plates could produce the effect of secondary reinforcement to the joint and improve the ductility of the joint effectively.
