Problems solved by technology

[0004] However, the cost of buckling-constrained bracing is high, and the economics of post-earthquake repairs are low. The existing bracing nodes do not fully exert their plastic capacity, and the excessive stiffness caused by the elastic design of the nodes makes it generate a large additional force on the frame beam-column joints. force can significantly reduce the ductility of frame beam-column joints

Abstract

The invention discloses a combined type buckling-restrained joint component. The combined type buckling-restrained joint component comprises a damping plate, a first guiding connecting plate, a secondguiding connecting plate, a supporting component connecting plate, a first connecting plate and a second connecting plate; and the plastic deformation of a support-frame structure system is concentrated at the position of a supporting connection joint. According to the principle of buckling energy consumption of metal materials, a supporting joint plate is creatively conceived as the damping plate, a buckling-restrained structure solves the buckling instability problem of the joint plate, the joint plate utilizes own plastic deformation ability to improve the energy consumption capacity of the structure, meanwhile, the combined structure facilitates the disassembly and replacement of the damping plate, the difficulty of construction operation is reduced, and the ability of the structure to quickly restore a use function after the disaster is improved.

Description

technical field [0001] The invention relates to the technical field of structure reinforcement and shock absorption, in particular to a combined buckling-constrained node member. Background technique [0002] Due to the low lateral stiffness of the simple frame structure system, supports are installed between beams and columns of the frame structure to form a "support-frame" double lateral force structural system. The installation of support members can significantly improve the lateral stiffness of the frame structure, thereby improving The ability of a structure to resist earthquake and wind loads. The support system includes: connecting node members and support members. At the beam-column node where the support is connected to the frame structure, post-anchoring techniques such as planting bars, mechanical and chemical anchor bolts are used to install L-shaped connectors for connecting the frame structure and node members, and the gusset plate connecting the support is v...
