Flexion energy dissipation preventing support

Abstract

The invention discloses a flection and energy consumption preventing brace which comprises a core stress member, a restriction member, an isolation layer positioned between the core stress member and the restriction member, and a connecting member connected with two ends of the core stress member. The core stress member comprises two steel plates; and an elastic filling material is arranged between two steel plates. As the elastic filling material is adopted to solve the problems of the flection and energy consumption after the double steel plates are stressed, the material for the isolation material only needs to realize the separation of the double steel plate and a restriction sleeve, does not need to consider reserving a gap with certain thickness; therefore, common lipin or an organic material is applied on the surface of the double steel plates to meet the requirement, so manufacturing difficulty is greatly reduced.

Description

technical field [0001] The invention belongs to the field of building structures, in particular to an energy-dissipating support. Background technique [0002] In recent decades, anti-buckling energy-dissipating braces have been widely used in countries and regions such as the United States, Japan, and Taiwan. The anti-buckling energy-dissipating brace is a kind of brace that does not buckle under tension and compression, and has more stable mechanical properties than traditional braces. The buckling restraint brace can not only improve the stiffness and ductility of the structure, but also use the hysteretic properties of the steel to consume the energy of the structure due to the horizontal load, which is of great significance to the improvement of the seismic capacity of the structure. [0003] After the Kobe earthquake in 1995, the anti-buckling restrained bracing system was widely used in Japan. Up to now, more than 300 buildings have used anti-buckling energy-dissipat...

AI Technical Summary

Problems solved by technology

[0007] 1. It is difficult to ensure uniform application of debonded materials. The key to the existing anti-buckling energy-dissipating support is to rely on the gap between the core material and the restraining sleeve. For mortar filling, it is necessary to vibrate the support, which can easily damage the debonded material on the surface of the core material;

[0008] 2. When the traditional anti-buckling energy-dissipating support is working, due to the heavy weight of the outer restraint sleeve, the core material and the outer sleeve are prone to slip and damage the support when the structure vibrates;

[0009] 3. The cross section of the connection between the core material and other structures has a sudden change, which is prone to damage;

[0010] 4. Self-heavy
