Abstract

The invention relates to a building component used for node angle displacement limitation and shock absorption, in particular to an angle-adjustable fan-shaped lead viscoelastic corner damper, and belongs to the field of structure engineering. The angle-adjustable fan-shaped lead viscoelastic corner damper mainly solves the problem that the existing fan-shaped lead viscoelastic corner damper component is only limited to be used at a 90-degree angle beam post node position and is difficult to adapt to the modern building structure form diversification. The angle-adjustable fan-shaped lead viscoelastic corner damper comprises a composite elastic body and two connecting plates, wherein the composite elastic body consists of elastic bodies, shearing steel plates, a cylindrical lead core and angle regulating steel plates; the elastic bodies and the shearing steel plates are alternately laminated; the cylindrical lead core transversely passes through the shearing steel plates and the elastic bodies; the shearing steel plates arranged at the outer side are connected with the angle regulating steel plates through screw bolts; and each elastic body, each shearing steel plate and each angle regulating steel plate are all in a fan shape concentric with the composite elastic body. The angle of the damper can be regulated into four different values, and the angle-adjustable fan-shaped lead viscoelastic corner damper is applicable to 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. ...
