Abstract
The report describes a series of tests carried out on the shaking table at Earthquake Engineering Research Center in which a base-isolated bridge deck model representing a typical highway bridge superstructure was subjected to a variety of earthquake inputs representing both real and artificially generated earthquake signals. Two different forms of isolation system were used in the testing program. One used natural rubber elastomeric layers reinforced by steel plates and the other set used the same bearings but with a lead plug inserted in a central hole.
