板式橡胶支座在连续梁桥减隔震设计中的应用

iming at the phenomenon that the fixed piers of the continuous beams have been damaged during the earthquakes, In this paper the seismic responses were carried on based on a four-span continuous beam, pot rubber bearing and laminated rubber bearing were selected, and corresponding finite element models were built. The results indicate that the distributions of the longitude seismic forces between the piers are more reasonable for the latter bearing, especially under the long period seismic excitations. The possiblity of adopting the laminated rubber bearing on the seismic control on the continuous beam were discussed, and the results can be referrd by the same bridges during designing.
