Base Isolation is widely used concept for protecting structures from seismic activity. In this study, Friction Pendulum System (FPS) and Triple Friction Pendulum System (TFPS) are used for passive control of the cable-stayed bridge. The main aim of this study is to compare seismic behaviour of bridge model isolated with FPS and TFPS using SAP2000 software. Several far-field ground excitations, near-fault ground excitations with fling steps and near-fault ground excitations with forward directivity are considered in seismic analysis of cable stayed bridge. Result of base shear and hysteresis loop are compared after analysis. It is examined that seismic behaviour of cable-stayed bridge isolated with TFPS proves to be more effective than that of cable-stayed bridge isolated with FPS.
