Background
The metal damper is considered to be reliable and stable at present and is familiar to engineering designers, and the principle of the action of the metal damper is that metal has good hysteresis characteristics after entering a plastic state and absorbs a large amount of energy in the elastic-plastic hysteresis deformation process so as to absorb the energy acting on the metal damper. Under the action of earthquake, the metal damper yields before the main structure, and consumes energy input into the structure by earthquake, thereby achieving the purpose of lightening the earthquake response of the structure.
