Therefore, the study on seismic resistance of bridge engineering is very important, the girder falling of the upper structure of the bridge is a main reason for the collapse of the bridge in the earthquake, and for this reason, a bridge seismic isolation and reduction system which is worthy of popularization is formed by adopting a support with a shock absorption and energy dissipation function between pier girders or directly controlling the relative displacement between pier girders of a large-span beam and between side pier girders of a cable-stayed bridge by using a damper. In addition, the anti-seismic design of the bridge structure is developed from strength-based design to ductility design, and the high-ductility bridge based on the ductility design can generate large residual displacement after encountering rare earthquake action, so that the normal use of the structure is influenced. Therefore, the metal buckling restrained brace and the bridge damping and energy dissipating device with the self-resetting function which are widely applied in the field of concrete frame building also become one of the research targets at present.

The metal damper is mainly constructed by mild steel, low-yield-point steel, lead, shape memory alloy and the like, has the advantages of stable hysteretic performance, various forms, economic cost and the like, but is relatively rarely applied in bridge engineering in China at present.
