Self-resetting anti-buckling energy dissipation support based on memory alloy

Abstract

The invention provides a self-resetting anti-buckling energy dissipation support based on a memory alloy. The self-resetting anti-buckling energy dissipation support comprises a core stress assembly and a tension-compression self-resetting mechanism, wherein the tension-compression self-resetting mechanism comprises connecting end plates, compression limiting hoops, tension limiting hoops, force transfer pieces, compression working memory alloy pieces and tension working memory alloy pieces; the connecting end plates are fixed at the two ends of the core stress assembly respectively; the compression limiting hoops sleeve the two sides of the periphery of the core stress assembly and are fixed at the two sides of the periphery of the core stress assembly; the tension limiting hoops sleeve the periphery of the core stress assembly and are located between the two compression limiting hoops; the tension working memory alloy pieces are connected between the two tension limiting hoops; the compression working memory alloy pieces are connected between the tension limiting hoops and the compression limiting hoops; and the force transfer pieces are connected between the tension limiting hoops and the connecting end plates. The self-resetting anti-buckling energy dissipation support based on the memory alloy has the advantages that the good self-resetting characteristic and energy dissipation characteristic can be achieved under the tension-compression action, the structure is simple, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of engineering structures, in particular to a self-resetting anti-buckling energy-dissipating support based on a memory alloy. Background technique [0002] In the field of engineering structures, energy dissipation and shock absorption technology has been widely used in the wind and earthquake resistance design of high-rise buildings, long-span bridges and other structures. The addition of energy dissipation and shock absorption components can effectively reduce the wind vibration or earthquake response of the main structure. Effectively reduce the damage of the main structure. Anti-buckling support is one of the common energy dissipation and shock absorbing components. Compared with traditional support members, it can achieve yield without buckling under tension or compression. It can provide a certain amount of additional stiffness and Large hysteretic energy consumption capacity. However, the biggest d...
