metal damper

Abstract

The invention provides a metal damper, and belongs to the technical field of building structure energy dissipation and damping. The damper comprises a metal core plate and a fixing device. The fixing device comprises a first fixing device and a second fixing device. The metal core plate is provided with a sine wave along the longitudinal direction. One end, along the longitudinal direction, of the metal core plate, is connected with the first fixing device; the other end, along the longitudinal direction, of the metal core plate, is connected with the second fixing device. According to the metal damper, the corrugated shape of the metal core plate is designed according to the sine wave waveform principle, and the proper metal core thickness, corrugation radius and the corrugation opening angle are selected according to the parameters. Because the sine wave metal damper possesses the sensitive displacement or deformation capacity, displacement or deformation recovery performance and good resistance to low-cycle fatigue elastic-plastic cumulative deformation capacity, thereby improving limit sensitivity of the displacement or deformation to the buildings and bridges; improving the energy-dissipation effect.

Description

technical field [0001] The invention relates to the technical field of energy dissipation and shock absorption of building structures, and more specifically relates to a metal damper. Background technique [0002] In recent years, a lot of research has been done on the isolation, vibration reduction and vibration control of engineering structures in my country. The traditional anti-seismic design is to resist earthquake action by enhancing the anti-seismic performance of the structure itself, but this anti-seismic method lacks self-regulation ability, and may not meet the safety requirements under uncertain earthquake action. Energy dissipation technology provides a reasonable and effective way for structures to resist earthquakes. Energy dissipation and shock absorption is to guide the seismic energy input into the structure to specially set mechanisms and components for absorption and dissipation, so as to achieve the purpose of protecting the safety of the main structure...

AI Technical Summary

Problems solved by technology

[0005] Due to the high rigidity of the metal plate damper itself, the response to the displacement or deformation of buildings and bridges is slow, and the limit capacity is insufficient.
