Unseating　may　be　one　of　the　most　severe　forms　of　damage　to　a　bridge　caused　by　an　earthquake;　such　an　event　may　lead　to　catastrophic　span　falling　or　collapse.　A　novel　elastomeric　bearing　incorporated　within　steel　ring　restrainers　(EB-SRRs)　to　prevent　the　unseating　of　bridges　is　therefore　proposed.　The　EB-SRRs　consists　mainly　of　an　elastomeric　bearing　in　the　center　and　multiple　steel　ring　restrainers　(SRRs)　symmetrically　distributed　on　both　sides.　The　finite　element　(FE)　model　of　the　EB-SRRs　is　established,　and　its　reliability　is　validated　using　data　from　earlier　experiments.　A　parametric　analysis　of　the　EB-SRR　performance　is　undertaken　using　the　FE　method.　Finally,　a　method　for　the　prediction　of　the　mechanical　behavior　of　the　EB-SRRs　is　proposed.　The　results　show　that　EB-SRRs　can　provide　multi-level　mechanical　properties:　compared　with　traditional　EB,　EB-SRRs　has　the　same　behavior　under　small　horizontal　load　but　provide　a　slight　increase　in　strength　and　energy　dissipation　under　moderate　horizontal　load　and　a　greater　increase　in　strength　and　energy　dissipation　under　large　horizontal　load.The　cross-section　height　h　and　cross-section　width　w　mainly　affect　the　ultimate　bearing　capacity　Fu　and　the　energy　dissipation　of　the　EB-SRRs;　steel　ring　radius　R,　guide　pulley　diameter　D,　and　straight　part　length　a　mainly　affect　the　ultimate　displacement　δu;　the　straight　part　length　a　significantly　affect　the　activation　displacement　δa.　The　method　of　predicting　the　force–displacement　curves　of　the　EB-SRRs　proposed　in　this　study　is　shown　to　be　accurate.　©　2023　Institution　of　Structural　Engineers
