Self-resetting energy-dissipating support structure and assembly method

Abstract

The invention provides a self-resetting energy-dissipating support structure and an assembly method. The self-resetting energy-dissipating supporting structure includes a frame body, a support rod, a self-resetting component and a frictional energy-consuming component. The self-resetting component includes a disc spring group, a limit ring, a disc The spring group and the limit ring are respectively set on the support rod, and the limit ring is located at both ends of the disc spring group, and the two sides of the disc spring group are respectively in contact with the inner sealing plate and the lower sealing plate. Manufactured; the frictional energy dissipation component includes a baffle and friction blocks welded to both ends of the baffle, the baffle is fixedly set on the support rod, and a friction groove is arranged on the inner side of the side sealing plate, and the friction block is set in the friction groove and can slide relative to the friction groove ; When the support rod is under pressure or tension, the friction block and the friction groove will displace relative to each other to consume energy through friction, and the disc spring group will deform and consume energy; when the external force is removed, the disc spring group can automatically return to its original shape. The self-resetting energy-dissipating support structure has the advantages of less structural damage and less residual deformation.

Description

technical field [0001] The invention belongs to the technical field of engineering energy consumption and shock absorption, such as structural engineering, mechanical engineering and underground engineering, and particularly relates to a self-reset energy-consuming support structure and an assembling method in structural engineering. Background technique [0002] The steel bracing frame can provide high elastic stiffness under small and medium earthquakes, so it is widely used in practical engineering. As a result, it loses its bearing capacity and energy dissipation capacity, which in turn affects the seismic performance of the frame. On the basis of traditional bracing, buckling restraint bracing can provide stable energy dissipation capacity, but due to its low stiffness after yielding, the main structure will retain a large residual deformation after a major earthquake. Existing studies have shown that residual deformation is one of the key factors determining the cost ...
