Problems solved by technology

[0004] However, there are still many defects in the design and performance of U-shaped metal dampers used for energy dissipation and shock absorption. Among them, one of the more common defects is: the damper produces yield deformation during the energy dissipation process, and after the energy dissipation ends , due to t

Abstract

The invention discloses a fabricated self-reset U-shaped metal damper. The metal damper comprises a steel plate composite component, a piston component, a box component, a bottom plate, a fastener, anelastic component and a plurality of U-shaped plate; the steel plate composite component comprises a flange plate and a web; two side plates of the U-shaped plates are fastened to a side plate of thepiston component and a side plate of the box component through a plurality of connecting members; the U-shaped plates enter an elastoplastic yielding state when vibrating, hysteresis is generated, and energy is consumed. According to the damper provided by the invention, the deformation energy consumption performance of the U-shaped plates can be adjusted according to different working conditionsthrough disassembly and replacement; metal has good hysteresis characteristics after entering the plastic state, and absorb a large amount of energy in the elastoplastic hysteresis deformation process, and the metal can provide additional damping and rigidity for the structure when being used as an energy-consuming device; and meanwhile, the damper components can be can be disassembled and replaced in time after fatigue fracture, the energy consumption effect is good, and the self-reset ability is high.

Description

technical field [0001] The invention relates to the technical field of energy dissipation and shock absorption, and more specifically relates to an assembled self-resetting U-shaped metal damper. Background technique [0002] In recent years, many relatively large earthquakes have taken place at home and abroad, causing great casualties and property losses. Earthquake disasters have become one of the most serious natural disasters faced by human beings. The traditional anti-seismic mainly relies on the deformation and energy consumption of the building itself to resist the seismic force, and this anti-seismic method will cause irreparable damage to the building. For decades, after continuous research by domestic and foreign scholars, it is proposed to add a damper to the building, and use the energy-dissipating element of the damper to absorb the energy input into the structure by the earthquake, thereby protecting the main load-bearing components of the building, that is, p...
