Abstract Under the action of earthquake, the dynamic interaction between the bridge pier and the surrounding water will have a great influence on the dynamic response of the structure. In this paper, a simplified analysis model of a continuous beam bridge with 2 degrees of freedom considering the hydrodynamic pressure is established, and its combined stiffness and additional mass are derived. The Lyapunov method for stochastic optimization of viscous damper parameters with the goal of minimizing the displacement of the pier top is proposed. On this basis, a simplified model of a sea-crossing continuous girder bridge with viscous dampers was optimized for damper parameters, and the seismic mitigation performance of the continuous girder bridge under the coupling of hydrodynamic pressure and earthquake was studied. The results show that the hydrodynamic pressure increases the seismic response of the bridge and have a greater impact on the dynamic response characteristics of the bridge. Seismic response to continuous girder bridges can be effectively reduced by viscous dampers and the seismic safety of the bridge structure are improved significantly.

Key words： continuous girder bridge hydrodynamic pressure viscous damper stochastic vibration Parameter optimization Seismic mitigation performance
