Abstract:

Finite element models of simply-supported beam bridge with lead rubber bearing， friction pendulum bearing and viscous damper was established separately based on ANSYS. Through changing seismic excitation， structural parameters and vibration reduction isolation device parameters， the earthquake-induced residual displacement of bridge was analyzed. The results showed that the residual displacement was sensitive to seismic spectrum characteristics，and it increased significantly both with the rise of peak acceleration and shear span ratio， and it increased with the enlarge of duration and pier height at the same time. The residual displacement was the most sensitive to the change in parameters of lead rubber bearing and friction pendulum bearing， while changes in parameters of viscous dampers had less impact on it. The residual displacement could be reduced by increasing yield force and post-yield stiffness of lead rubber bearing， friction coefficient of friction pendulum bearing， length of the damping hole， outer diameter and viscosity of silicone oil of viscous damper， and by reducing curvature radius of friction pendulum bearing. The research results can provide theoretical basis for the improvement of disaster resilience of bridge structures.
