Embodiment Construction

[0033] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0034] The invention provides a snap-type two-stage friction energy dissipation damper, which is applied to middle and high-rise buildings, high-rise buildings, and large-span spatial structures, and can also be applied to the reinforcement and transformation of existing buildings. The damper can not only provide rigidity for the building structure under the action of small earthquakes and wind vibration, but also provide friction energy consumption for the building structure under the action of moderate and large earthquakes, which has a good energy consumption effect and solves the existing problems. The problem of low efficiency of friction dampers under small earthquakes and wind vibrations. The damper of the present invention is connected with a shear pin between the sliding components, and the setting direction of the shear pin is perpendicular to the sl...

Abstract

The invention relates to a snap-in two-stage friction energy dissipation damper. The snap-in two-stage friction energy dissipation damper comprises sliding assemblies which are connected and can slide relatively, a sliding plate between the sliding assemblies is arranged in a penetrating and inserting mode, and a siding friction layer is arranged between the adjacent sliding plates in a cushioned mode, the first side of each sliding assembly is provided with an extension plate, and oppositely-arranged shear pin connecting pieces are arranged between the two adjacent extension plates; shear pins are used for connecting the oppositely-arranged shear pin connecting pieces in a penetrating and inserting mode, and the arrangement direction of the shear pins is perpendicular to the sliding direction of the sliding assemblies. The damper has the specific two-stage mechanical property, under the small earthquake and wind vibration effect, the shear pins are stressed, the damper has the enough rigidity, and therefore the structure is controlled to deform under the small earthquake and wind vibration effect. Under the intermediate-earthquake and large earthquake effect, the shear pins are sheared, the structural rigidity is lowered, and then, the horizontal earthquake force borne by the structure is reduced; meanwhile, the friction energy dissipation effect is brought into play, and earthquake energy of the input structure of intermediate earthquakes and large earthquakes are dissipated.

Description

Technical field [0001] The invention relates to the technical field of structural engineering, in particular to a snap-in two-stage friction energy dissipation damper. Background technique [0002] Building energy dissipation (vibration) technology is a kind of effective structure passive control technology. By arranging energy-dissipating and damping (vibration) devices at the relatively large deformation of the structure, the dynamic response of the structure under the action of earthquake, wind or other dynamic loads can be effectively reduced. [0003] The ideal performance of the energy dissipation (vibration) device is: the damper does not bear vertical load; under the action of small earthquakes and wind vibration, the damper provides lateral rigidity to the structure, at this time the damper can be regarded as a support or a diagonal brace Component; under the action of moderate and large earthquakes, the damper does not provide lateral stiffness to the structure, thereby ...
