Problems solved by technology

However, due to the increasingly complex engineering structures in the prior art, in addition to the axial and shear deformations of the structural members under the earthquake, there are also a large number of rotational deformations
The energy dissipation and shock absorbing devices in the prior art cannot dissipate the seismic energy by using the rotational deformation of structural members

Abstract

The invention relates to a rotary friction energy dissipator. The rotary friction energy dissipator comprises a first rotary assembly, a second rotary assembly, a plurality of friction plates and a plurality of fasteners, wherein the first rotary assembly comprises a first connecting plate and first clamping plates, and the second rotary assembly comprises a second connecting plate and second clamping plates; the plurality of first clamping plates and the plurality of second clamping plates are sequentially spaced in parallel and rotatably connected, the friction plates are attached between the first clamping plates and the second clamping plates, and the fasteners are arranged in parallel and at intervals and sequentially penetrate through the second clamping plates, the friction plates and the first clamping plates; and the rotation points of the first clamping plates and the second clamping plates are taken as centers, and a plurality of arc through holes for the fasteners to penetrate through are formed in the first clamping plates. According to the rotary friction energy dissipater, when a first connecting piece and a second connecting piece are subjected to rotary deformation, the fasteners slide along the arc through holes, seismic energy is dissipated, and engineering structure damage is reduced.

Description

technical field [0001] The invention relates to building structure energy-dissipating components, in particular to a rotational friction energy-dissipating device. Background technique [0002] Earthquake disasters pose a huge threat to the safety of human life and property, and the use of energy dissipation and shock absorption technology to protect building engineering structures is a limited means to reduce earthquake disasters. Energy dissipation and shock absorption technology is to install additional energy absorbers in the structure to absorb earthquake energy, only to protect the main structural components and reduce damage. [0003] Energy dissipation and shock absorbing devices in the prior art can be divided into the following categories according to structural deformation: axial type and shearing type, that is, energy dissipation and shock absorbing devices use axial deformation and shear deformation in the structure to dissipate energy. For example, the anti-bu...
