Angle adjustable sector lead viscoelastic corner damper

Abstract

The invention relates to a building component for limiting the angular displacement of joints and shock absorption, in particular to an angle-adjustable fan-shaped lead viscoelastic corner damper, which belongs to the field of structural engineering and mainly solves the problem of the existing fan-shaped lead viscoelastic corner damper Components are limited to use at beam-column joints at 90° angles, which is difficult to adapt to the diversification of modern architectural structures. The invention includes a composite elastic body and two connecting plates, wherein the composite elastic body is composed of an elastic body, a shear steel plate, a columnar lead core and an angle adjustment steel plate; The steel plate and the elastic body, the outer shear steel plate and the angle adjustment steel plate are connected by bolts; each elastic body, the shear steel plate and the angle adjustment steel plate are concentric sectors of the composite elastic body. The damper angle of the invention can be adjusted to four different angles, and is suitable for building structures with various angles.

Description

technical field [0001] The invention relates to a building component for limiting angular displacement of nodes and shock absorption, in particular to an angle-adjustable fan-shaped lead viscoelastic corner damper, which belongs to the field of structural engineering. Background technique [0002] The traditional anti-seismic structure relies on the resistance of the structure itself. By increasing the cross-section of the column and increasing the reinforcement of the beam-column joints to improve the seismic performance of the structural columns and beam-column joints, this not only causes more material consumption, but also makes the Building self-weight increases, and the loss outweighs the gain. The existing lead viscoelastic damper, which can be used for strengthening beam-column joints, is a composite damper, which uses the plastic deformation of lead after shearing or extrusion yielding and the shear hysteretic deformation of viscoelastic materials to consume can. ...

Problems solved by technology

[0004] The existing fan-shaped lead viscoelastic corner damper components (such as the authorized announcement numbers are CN101736828B and CN101713226B) have fully utilized the energy dissipation effect of the viscoelastic damper under the action of small deformation and the yield displacement of the lead shear and extrusion type damper The advantages of small size and large limit restoring force make it perform well when applied to earthquake response control and wind vibration response control, but it is limited to use at beam-column joints at 90° angles, and the building structure forms are diverse in socialist modernization construction Under the background of globalization and complexity, a single 90° fan-shaped corner damper cannot meet the installation at large-angle beam-column joints or steel structure joints, and the production of multi-angle corner dampers has higher requirements for production technology and costs also more expensive

There is no corresponding fan-shaped corner damper that can be adjusted at home and abroad
