The bearings usually do not provide a positive connection but in contact with girder and pier by only gravitational forces. In this study, a model test bridge of about ½ scale have been shaken under low to moderate earth quakes to determine the change in response of the bridge with different seismic isolation configurations. Three configurations of bearings are elastomeric bearings, lead core bearings and ball rubber bearings. The bridges supported with lead rubber or ball rubber bearings’ deck displacements are dampened out in a short period of time compared to the tests of bridges with elastomeric bearings as expected. The seismic retrofit goals can be defined for the old bridges based on the target structural response in terms of displacements and forces.
