Abstract

Damping and isolation effect of high-damping rubber bearing with different combination have been studied for a continuous girder bridge. Dynamic time-history analysis has been taken by earthquake waves with exceeding probability to be 40 percent, 10 percent and 2 percent. The influence for seismic responses of bridge caused by sliding bearing set on transitional pier has been discuss. Research results show that the sliding bearings set on transitional piers have weakened the load sharing percent of transitional piers. The displacements of sliding bearings are larger than the bearings set on continuous piers, so that the load distribution of piers is nonuniform. The load sharing is much more reasonable when high-damping rubber bearings were set on all the piers, and the dynamical response of bridge was greatly decreases.
