Abstract

The invention provides a barrel type tension-compression damper with built-in semicircular wave energy dissipation separation steel plates, and belongs to the field of vibration control of a buildingstructure. The barrel type tension-compression damper comprises connection plates, connection plate screw holes, fixed end plates, outer barrel side plates, outer barrel end plates, end part energy dissipation steel plates, the semicircular wave energy dissipation separation steel plates, energy dissipation reinforced tension-compression plates, coordinated connection reinforcements, an elastic binding filling material, tension-compression connectors, a foamed aluminium energy dissipation material, spring energy dissipation bodies and outer barrel cover boards; a main body of the barrel type tension-compression damper with the built-in semicircular wave energy dissipation separation steel plates is of a structure formed by the surrounding of the outer barrel side plates, the outer barrel end plates and the outer barrel cover boards. The barrel type tension-compression damper with the built-in semicircular wave energy dissipation separation steel plates has the advantages that by adopting a structural design that for two rows of semicircular wave energy dissipation separation steel plates, wave crests and wave crests are opposite, wave troughs and wave troughs are opposite, the wavetroughs are connected by the spring energy dissipation bodies and the wave crests are connected by the coordinated connection reinforcements, mutual coordination can be implemented, coordinated energy dissipation capacity of the barrel type tension-compression damper is improved, and an earthquake response of the building structure can be reduced.

Description

technical field [0001] The invention belongs to the field of vibration control of building structures, in particular to a cylindrical tension-compression damper with a built-in semicircular wave energy-dissipating partition steel plate. Background technique [0002] Metal yield dampers are various forms of damping energy dissipators made of mild steel or other soft metal materials. Metals have good hysteretic properties after yielding, and use the elastic-plastic hysteretic deformation energy dissipation of some metals, including mild steel dampers, lead dampers and shape memory alloy dampers. The mechanism of its vibration control on the structure is to dissipate part of the energy of the structure vibration through the yield hysteresis energy consumption of the metal, so as to reduce the structural response. The mild steel damper is to make full use of the soft steel after entering the plastic stage Good hysteresis characteristics. In 1972, American scholars such as Kell...

Problems solved by technology

At present, the initial stiffness of many dampers is not large enough, the yield dispersion area of ​​the material is not large enough, and the design of the energy dissipation structure is not very sufficient, so that the energy such as kinetic energy or elastic potential energy of the structure cannot be fully converted into heat energy and dissipated. Many dampers are only It can increase the overall stiffness of the building structure during normal use, but when a large earthquake occurs, many dampers cannot meet the requirements of reducing the seismic response of the building structure
