Abstract

The invention discloses an assembled self-resetting out-of-plane bending metal damper, which comprises a steel plate composite component, a piston component, a box type component, a bottom plate, a fastener, an elastic component, and energy consuming components. The steel plate composite component comprises a flange plate and a web; the plurality of energy consuming components comprise connectingplates and energy consuming plates; panels of the connecting plates are arranged in parallel with a side plate of the piston component and tightly connected with the side plates of the piston component and the box type component respectively through a plurality of connecting members; the plurality of energy consumption plates are fixed in parallel between the two connecting plates, the energy consumption plates are in rectangular shapes, and diamond-shaped through holes are formed in the centers; the energy consumption plates are large in yield areas and uniform in plastic distribution, and during energy consumption, various points of the energy consumption plates simultaneously enter plastic deformation. According to assembled self-resetting out-of-plane bending metal damper, deformationenergy consumption performance of the energy consuming plates can be adjusted according to different working conditions by means of disassembly and replacement; and at the same time, the damper component can be disassembled and replaced in time after fatigue damage of the component, the energy consumption effect is good, and self-resetting capability 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 out-of-plane bending metal damper. Background technique [0002] In recent years, many relatively large earthquakes have occurred 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 method mainly relies on the deformation and energy consumption of the building itself to resist the earthquake force. 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 build...

AI Technical Summary

Problems solved by technology

[0004] However, there are still many defects in the design and performance of out-of-plane curved 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 , due to the lack of self-resetting ability or too small self-resetting ability, the energy-dissipating element still has a large yield deformation. At this time, the residual deformation of the energy-dissipating element will bring a negative effect that is difficult to repair on the stress and use function of the building structure
