Description
Technical Field

Background
The energy dissipation and shock absorption technology is one of the effective means for reducing the earthquake damage at present, and an energy dissipation and shock absorption device is added in a building to absorb and dissipate the earthquake energy, so that the shock absorption mechanism is clear. The metal damper is used as a displacement damper, and the earthquake energy is mainly dissipated through plastic deformation of the energy dissipation steel plate. Most of the currently used metal dampers are of integrated structures, when an earthquake occurs, no matter the magnitude of the earthquake is uniform, the metal dampers deform, if the metal dampers are designed to be small-earthquake elasticity, the metal dampers consume energy only under medium earthquake and large earthquake, and the price is greatly increased and the metal dampers are not widely used; if the whole metal damper is designed to have small earthquake yielding energy consumption, the rigidity of the damper added to the structure is larger, the substrate shearing force of the structure is increased, and the structure is unfavorable to the main structure of the building. Therefore, the integrated metal damper cannot meet the earthquake fortification target 'small earthquake is not bad, medium earthquake is repairable and large earthquake is not collapse' which is followed by the earthquake fortification standard in China.
