Plate type metal damper constrained by steel-concrete combined plates

Abstract

The invention discloses a plate type metal damper constrained by steel-concrete combined plates. The metal damper comprises a metal core plate and two constraint plates. The metal core plate is clamped between the two constraint plates and provided with a plurality of strip-shaped vertical holes, and the strip-shaped vertical holes divide a plate body of the metal core plate into a plurality of strips. Each constraint plate comprises a concrete layer attached to the metal core plate, and a steel box covering the concrete layer. The plate type metal damper constrained by the steel-concrete combined plates has the advantages of being more stable in performance, better in quality, convenient to install, wide in application range and the like.

Description

technical field [0001] The invention belongs to the technical field of building vibration reduction, in particular to a plate-type metal damper constrained by a steel-concrete composite plate. Background technique [0002] In order to control the dynamic response of building structures under wind load and earthquake load, it is often necessary to set up mechanical devices to dissipate the vibration energy, so as to reduce vibration and protect the main structure. The vibration control of structures is mainly divided into passive control, semi-active control, active control and hybrid control. Among them, passive control is to install energy-dissipating dampers at appropriate parts of the structure to absorb the energy input into the structure by wind or earthquakes, so as to reduce and adjust the dynamic response of the structure. Passive control technology is widely used in engineering construction because of its simple and reliable structure, stable energy consumption per...

Problems solved by technology

[0004] However, the currently commonly used restraint slab is a reinforced concrete layer, which has obvious shortcomings, as follows: (1) Due to the need for the thickness of the steel protective layer and the influence of the force outside the plane, the thickness of the restraint slab is relatively large, resulting in a large self-weight, which is not Conducive to architectural beauty and hoisting installation

(2) The concrete layer is prone to cracking and bump damage, which requires high processing technology, transportation and hoisting methods, which is not conducive to the quality control and application promotion of the damper
