Double-restraint self-reset buckling-proof energy-dissipation support

Abstract

The invention provides a double-restraint self-reset buckling-proof energy-dissipation support. The support consists of a novel disc spring self-reset assembly and a buckling-proof support assembly, wherein the self-reset assembly has a friction energy dissipation function, great self-reset performance under the action of medium and small earthquakes and an excellent energy dissipation capacity; the buckling-proof support assembly consists of a core plate, a limiting plate, constraint channel steel and a bolt, wherein the core plate adopts a linear section-variable form, and carbon fiber clothis stuck to the core plate locally to form a local reinforcing section in order to achieve the effect of a preset necking section. By fully utilizing the energy dissipation performance of the core plate in a necking stage of the steel, the accumulated energy dissipation capacity and hysteresis performance of the core plate are improved, and the performance of the core plate shows that a multi-wave buckling phenomenon of the support core plate is obviously inhibited and the accumulated ductility of the core plate is obviously improved. The double-restraint self-reset buckling-proof energy-dissipation support has good self-reset performance and great energy-dissipation performance and is simple in structure, convenient to install and easy to popularize.

Description

technical field

[0001] The invention relates to the field of civil engineering, and relates to an anti-seismic support structure, in particular to a double-constraint self-resetting anti-buckling energy-dissipating support. Background technique

[0002] In order to make the structure resistant to earthquakes and not to collapse and endanger life safety, the traditional earthquake-resistant lateral force structural system emphasizes the ductility design of the structure, and dissipates the seismic energy through the yield mechanism of structural components. However, due to the energy consumption through the plastic deformation of structural components, the structure has a large residual deformation after the earthquake, which greatly increases the difficulty and cost of repair. With the development of economy and society, it has become the focus of people's attention to improve the ability of rapid recovery of urban functions after earthquakes. Therefore, how to effectively ...
