The characteristics of seismic design of continuous girder bridges are compared with nonlinear dissipative devices and viscous dampers. The research results have been applied in this project, which has solved the problem of seismic resistance of the bridge in the longitudinal direction. The results show that due to the adoption of special seismic measures, the seismic design of the bridge and the controllability of the design are enhanced, which makes it easier for designers to solve the seismic design problems of similar bridges.
