Problems solved by technology

Most of the existing dampers belong to the package structure, which is not conducive to on-site installation and debugging, and the maintenance cost is high; at the same time, due to the damper with high yield strength, the characteristics of hysteretic energy consumption of the material cannot be fully utilized under medium and small earthquakes. The shock absorption effect is often lower than the design value

Abstract

The present invention relates to one kind of adjustable low yield point composite metal damper, and belongs to the field of shock resisting structural engineering technology and wind resisting technology. The adjustable low yield point composite metal damper consists of one first energy dissipating metal plate of material with yield strength greater than 200 MPa, one second energy dissipating metal plate of material with yield strength lower than 200 MPa, two horizontal connecting steel plates fixed to building structure, angle steel, high strength screws and one hollowed part. The first energy dissipating metal plate and the second energy dissipating metal plate are staggered and fixed between the horizontal connecting steel plates. The present invention is suitable for use in the crossed support point and the joint between beam and wall or column. The present invention has high energy dissipating capacity and other advantages.

Description

technical field [0001] The invention relates to an adjustable metal composite low-yield point damper, which belongs to the technical field of anti-seismic, shock-absorbing and wind-resistant structural engineering. Background technique [0002] Building structures under the action of strong earthquakes and strong winds should have sufficient energy dissipation capacity to avoid damage. Traditional earthquake-resistant and wind-resistant structural systems consume energy through the damage of structures and load-bearing components, resulting in varying degrees of damage or even collapse of structural components, which is unreasonable and unsafe. Structural energy dissipation and shock absorption technology is a new earthquake-resistant and disaster-prevention technology. In the structural system using energy dissipation and shock absorption technology, some non-load-bearing members of the structure are designed as special elements with greater energy dissipation capacity - da...
