Abstract

The invention discloses an easily-reset high-energy consumption buckling-restrained brace, so as to solve the problems of large residual deformation and small energy consumption of a single material buckling-resistant brace in the prior art. The effects that most of the energy in earthquake can be dissipated and most of the residual deformation after earthquake can be restored can be achieved. Inthe technical scheme, the easily-reset high-energy consumption buckling-restrained brace comprises a self-reset energy consumption mechanism and a shell mechanism, wherein the self-reset energy consumption mechanism can slide in the shell mechanism under effects of an external pulling force or pressure; the self-reset energy consumption mechanism comprises two core plates of different materials, and backing plates are arranged between the end parts of the two core plates; the two core plates cooperate to reduce horizontal displacement so as to reduce the acceleration of displacement between layers during the earthquake; and the shell mechanism comprises multiple sleeves connected to the middle parts of the core plates and form restraints towards the core plates.

Description

technical field [0001] The invention relates to the field of building steel structures, in particular to an easy-to-reset, high-energy-consuming buckling-constrained support. Background technique [0002] The support system is one of the basic systems in the steel frame structure. Under earthquake action, the steel support bears a large part of the horizontal shear force to reduce the horizontal displacement of the overall structure. Ordinary supports will buckle under compression. When the supports buckle under compression, the stiffness and bearing capacity will decrease sharply. When the support gradually changes from the buckling state to the tension state, the internal force and stiffness of the support are close to zero. Therefore, the hysteretic performance of ordinary supports is poor under repeated loads. [0003] Therefore, in order to solve the problem of buckling under compression and poor hysteresis performance of ordinary supports, anti-buckling supports are...
