Earthquake-induced ground motions are the most severe and unpredictable threats to the structures all around the world. Therefore, designing earthquake protective systems has become an extremely challenging problem in civil engineering. Base isolation is one of the most popular and widely adopted methods of protecting structures against earthquake forces. The present paper reports the results obtained from the shaking table experimental study, which was aimed to verify the effectiveness of the Polymeric Bearings (PB), as a proposal of a new base isolation system, in suppressing structural vibrations under strong ground motions. The dynamic behaviour of two steel structure models, both fixed-base and base-isolated, subjected to the El Centro earthquake, was studied. The reduction in lateral response was measured by comparing the peak accelerations recorded at the top floor of the analyzed models, with and without PBs. The results of the study indicate that installation of the PBs leads to significant improvement in dynamic response by suppressing structural vibrations under earthquake excitation.
