The invention provides a disc spring slope self-resetting buckling restrained brace, which belongs to the technical field of buckling restrained braces and comprises an energy consumption system and a self-resetting system. The energy dissipation system comprises an energy dissipation core plate, a restraining plate and a filling plate, the energy dissipation core plate is provided with an energy dissipation section and a connecting section, and the restraining plate and the filling plate are used for restraining out-of-plane deformation generated after the energy dissipation section is pressed and yielded; the self-resetting mechanism comprises outer resetting plates and inner resetting plates, slope surface structures in sliding fit are arranged on the opposite faces of the outer resetting plates and the inner resetting plates, the two outer resetting plates are connected through an elastic connecting assembly, and the elastic connecting assembly provides elastic restoring force for relative sliding of slope surfaces between the inner resetting plates and the outer resetting plates. According to the disc spring slope surface self-resetting buckling restrained brace, post-earthquake residual deformation of an energy dissipation component can be eliminated, the structure is simpler, the manufacturing cost is lower, and wide application in engineering structures is facilitated.
Description
technical field [0001] The invention belongs to the technical field of buckling constrained supports, and more specifically relates to a disc spring slope self-resetting buckling constrained support. Background technique [0002] Buckling-restrained bracing is a ductile lateral force-resistant member widely used in frame structures. It provides lateral stiffness for the frame, controls the lateral deformation mode of the main structure, and ensures that the structure has sufficient ductility reserves to meet the deformation requirements during earthquakes, thereby Avoid structural collapse during strong earthquakes. But at the same time, a large plastic deformation will be generated in the buckling restrained brace to dissipate the seismic energy, resulting in the structure prone to severe residual deformation after strong earthquakes. According to statistics, under strong earthquake excitation, the average residual deformation of buckling-constrained bracing frames reaches...
