TJC buckling restrained bracing member

Abstract

The invention provides a TJC buckling restrained bracing member which is also called as a TJC buckling restrained brace. The TJC buckling restrained bracing member is characterized by comprising a core material part and supporting end part nodes, wherein the core material part is composed of a plurality of core veneers, while the supporting end part nodes are composed of a plurality of stiffening ribs; the first end surface of the two ends of each supporting end part node is at least provided with a first groove matched with the core material part; and the core material part is inserted into the first groove, so that the core material part is connected with the supporting end part nodes. According to the TJC buckling restrained bracing member provided by the invention, high-strength steel is adopted for the supporting end part nodes and low-strength steel or low-yield point steel is adopted for the core material part, so that the steel consumption quantity is reduced; the stiffening ribs of the supporting end part nodes penetrate through a sleeve so that the stability design is uncoupled with the strength design; the bending resistance ability of a supporting node is improved through an outer node hoop; and the breakage of the buckling restrained brace under heavy vibration is avoided through the design of locking plates and steel angles.

Description

technical field [0001] The invention relates to the field of architecture, especially the field of building structure support, and in particular, to a buckling-constrained support member used for support in a building structure system. Background technique [0002] Buckling-restrained brace, also known as unbonded brace, is a new type of anti-seismic energy-dissipating member with superior performance, an energy-dissipating brace that can yield under both tension and compression, and improves the traditional The disadvantage of buckling occurs, which improves the seismic performance of the structure. [0003] Frame structure is a common structural form of high-rise buildings, but its lateral stiffness and bearing capacity are limited, and its lateral displacement is relatively large under wind load or earthquake, which limits its construction height to a certain extent. In order to solve the problem of weak lateral stiffness and strength of the frame structure, additional s...

Problems solved by technology

However, the existing buckling-constrained supports are not very economical, and the production cost is high. This is because the design needs to ensure that the support nodes are in an elastic state. The usual method is to increase the cross-sectional area
