Based on the particular dynamic characteristic of self-anchored suspension bridge,the lead extrusion dampers are proposed to install between the deck and the anchor(auxiliary) piers to improve the transverse seismic response of the bridge structure.

Based on the particular dynamic characteristic of self-anchored suspension bridge,a designing scheme was proposed to install the viscous dampers or the lead extrusion dampers between the deck and the main tower to improve the longitudinal seismic response of the bridge structure.
