The　widespread　use　of　seismic　isolation　to　protect　structures　from　damage　has　already　been　proven　as　an　effective　and　economical　method.　In　order　to　investigate　the　seismic　performance　and　isolation　effect　of　isolated　bridge　with　the　traditional　friction　pendulum　bearing　(FPB)　and　the　novel　triple　friction　pendulum　bearing　(TFPB),　the　force-displacement　hysteretic　relationships　of　FPB　and　TFPB　were　validated　by　the　displacement-controlled　tests,　and　the　shaking　table　tests　were　carried　out　on　a　1/10　scaled　simple-supported　bridge　model　with　FPBs　and　TFPBs　under　bi-directional　earthquake　excitations.　The　effects　of　the　friction　coefficients　and　the　radius　of　the　TFPB　on　the　seismic　responses　were　analysed　using　the　extensive　experimental　results.　The　experimental　data　and　the　numerical　results　show　that　the　TFPB　can　be　reliably　used　for　the　passive　device　to　control　the　seismic　response　of　the　bridge,　which　could　satisfy　the　demand　of　performance-based　seismic　design　philosophy　in　high　seismicity　regions.　In　addition,　the　results　illustrate　that　the　bi-directional　interaction　of　the　TFPB　has　effects　on　the　dynamic　responses　of　the　bridge.　If　the　bi-directional　interaction　is　ignored,　the　deck　displacements　are　underestimated,　which　can　be　crucial　from　the　design　point　of　view.
