Because the metal material yield point used by the metal shearing supporting steel plate is usually higher and is difficult to enter an energy consumption state under the action of strong wind, the supporting steel plate can only play a role under medium and large earthquakes, and the applicability of the supporting steel plate under small earthquakes needs to be improved.
As another commonly-used energy-consuming and shock-absorbing device, the buckling-restrained energy-consuming brace has a brace form with double functions of a common brace and a metal energy-consuming brace steel plate. Under a small earthquake, the buckling restrained brace works like an ordinary brace which is not unstable, and provides lateral rigidity to the structure. Under the condition of medium or large earthquake, due to the lateral restraint of the outer-wrapped restraining member, the yielding section of the inner supporting core can fully yield and dissipate earthquake energy in a full section under the condition of tension or compression, so that most of the main structure keeps elasticity, and the large earthquake of the building can be repaired more easily. The buckling-restrained energy-dissipation brace has the advantages of clear damping mechanism, obvious damping effect, simple structure, wide application range, convenience in maintenance and the like, is valued by numerous researchers at home and abroad, so that the researchers at home and abroad research and develop buckling-restrained energy-dissipation braces of various types and different structures at present, and the buckling-restrained energy-dissipation brace is applied to new construction and building earthquake-resistant reinforcement engineering, and obtains good economic benefit and social benefit.
