Optimal allocation and seismic isolation effect analysis of high-damping rubber bearing for Beam Bridge

As the seismic isolation technique was widely use in aseismic design of bridges, the high-damping rubber bearing were applied to many bridges in order to reduce the seismic response of bridge. Compare the seismic isolation effect of different model high-damping rubber bearing and laminated rubber bearing, the optimal proposal of bearings has been suggested. Sliding bearings used on side piers caused the earthquake distributed unevenly among piers, as changed to high-damping rubber bearing, the seismic response of bridge have effectively controlled into allowable range.
