A Displacement Amplified Corrugated Web Damper

Abstract

The invention relates to a displacement amplified corrugated web damper, comprising an upper connecting plate with a rack, a gear, a double gear, a central shaft, a lower connecting plate with a rack, a frame, a chute beam, and a fixed bottom beam , corrugated web damper; it has the characteristics of simple structural design, low material selection and processing costs, convenient overall installation and construction, firmness and durability, etc. When the deformation speed and displacement between the structural layers are relatively small, it can be effectively Rapidly amplify the deformation, increase the relative displacement of the damper, increase the damping of the structure, and give full play to the energy dissipation and shock absorption capacity of the damper, thereby improving the overall energy dissipation capacity of the structure and effectively reducing the earthquake response to the building structure. s damage.

Description

technical field [0001] The invention relates to a displacement amplification corrugated web damper. Background technique [0002] Under the action of a large earthquake, the traditional structure mainly relies on some components to absorb a large amount of seismic energy, so that the entire structure enters an elastic-plastic state or even yields and fails, which leads to the entire structure being irreparable or even directly collapsed after the earthquake. Structural energy dissipation and shock absorption technology is a new earthquake-resistant and disaster-prevention technology. By setting shock-absorbing components and energy dissipators in certain parts of the structure with large deformations, such as viscous dampers, mild steel dampers, and friction dampers Wait. When encountering earthquake loads and wind loads, these energy-dissipating components can quickly enter the energy-dissipating state, consume the energy transmitted to the structure by the earthquake thro...

AI Technical Summary

Problems solved by technology

[0003] At present, in the field of structural energy dissipation and shock absorption technology, the biggest problem with dampers is that they cannot fully exert their energy dissipation and shock absorption capabilities.

When the damper is working, its speed and displacement are the same as the speed and displacement of the structural connection point. When the speed and displacement of the structural connection point are relatively small, the elastic-plastic deformation of the damper is small, so that it cannot fully exert its energy dissipation and shock absorption.
