To　study　the　seismic　isolation　effect　of　adjustable　height　seismic　isolation　rubber　bearing,　a　continuous　girder　bridge　was　subjected　to　a　shaking　table　test　study　with　full　bridge　scaling　to　compare　the　seismic　isolation　effects　of　plate　rubber　bearings,　natural　rubber　bearings　(LNR)　and　adjustable　height　seismic　isolation　rubber　bearings　under　different　types　of　seismic　waves,　loading　directions　and　seismic　intensities.The　test　results　show　that　when　the　seismic　intensity　is　small,　the　seismic　isolation　performance　of　the　three　types　of　bearings　is　relatively　close.　But　when　the　seismic　intensity　is　large,　the　seismic　isolation　effect　of　the　adjustable　height　isolation　bearing　is　better　than　that　of　the　plate　rubber　bearing　and　LNR　bearing.　Adjustable　height　isolation　rubber　bearing　can　significantly　reduce　the　acceleration　of　the　bridge　deck　plate,　shear　force　and　bending　moment　in　the　bottom　of　piers.　　©　Published　under　licence　by　IOP　Publishing　Ltd.
