In　order　to　explore　the　seismic　response　rules　and　the　seismic　performance　of　base　rocking　isolation　bridge　piers　with　different　structure　details　under　different　levels　of　seismic　actions,　two　new　models　of　base　rocking　isolation　bridge　piers　were　proposed　in　this　paper.　The　seismic　response　rules　and　the　seismic　performance　of　the　two　proposed　rocking　isolation　bridge　piers　were　investigated　by　means　of　shaking　table　test　and　numerical　simulation.　The　experimental　results　show　that　the　base　rocking　isolation　bridge　piers　have　no　serious　failure　and　damage.　The　bending　deformation　of　restrictor　steel　plates　and　the　sliding　of　lift-restraint　members　are　the　main　failure　characteristics　under　different　levels　of　seismic　actions,　indicating　a　good　seismic　performace.　Compared　with　traditional　bridge　piers,　the　base　rocking　isolation　bridge　piers　could　significantly　reduce　the　horizontal　acceleration　at　the　top　of　the　pier　and　the　strain　response　at　the　bottom　of　the　pier.　However,　the　horizontal　displacement　at　the　top　of　the　pier　could　be　increased　accordingly.　Therefore,　the　horizontal　displacement　at　the　top　of　the　pier　should　be　considerd　as　the　main　design　parameter　in　the　design　of　base　rocking　isolation　bridge　piers.　The　modified　Winkler　two-spring　models　were　proposed　to　simulate　the　seismic　response　of　base　rocking　isolation　bridge　piers.　By　comparing　with　the　results　of　the　shaking　table　test,　the　proposed　calculated　models　can　simulate　the　rocking　behaviours　and　seismic　response　rules　of　the　two　base　rocking　isolation　bridge　piers.　©　2020,　Editorial　Office　of　Journal　of　Building　Structures.　All　right　reserved.
