Abstract
In order to reveal the vibration isolation performance of new composite rubber bearings (CRBs), this paper establishes a numerical model of composite rubber bearings based on SAP2000, and studies the seismic response of bridges supported by LNB and CRB at different pier heights. The results show that compared with LNB, CRB can effectively reduce the shear force and bending moment of the pier without increasing the structural displacement.Compared with LNB, the advantages of CRB in isolation performance vary little with pier height, which indicates that CRB has broad application prospects..
