The　purpose　is　to　study　the　seismic　reduction　effect　of　an　isolated　structure,　with　wind-resistant　bearings　(WRBs)　setting　on　its　isolation　layer　to　withstand　great　wind　load,　and　the　working　mechanism　of　the　WRB.　In　this　paper,　two　isolation　models　with/without　WRBs,　taking　an　actual　engineering　as　the　background,　are　established　in　the　finite　element　software　ETABS.　The　one　with　WRBs　has　horizontal　damping　coefficient　less　than　0.40　while　the　other　between　0.40　and　0.53.　WRBs　are　simulated　by　Plastic　1　element　and　the　collaborative　work　between　them　and　isolation　layer　is　described　by　a　mechanical　model.　Time　history　analysis　is　conducted　on　the　models　to　compare　their　responses　under　earthquake　excitations.　Results　show　that　the　one　with　WRBs,　but　less　lead-rubber　bearings　(LRBs),　has　better　damping　effect　than　the　other,　although　they　both　can　meet　wind　requirements.　It　is　also　shown　that　under　normal　conditions　and　small　earthquakes,　WRBs　function　well　and　the　isolation　layer　will　not　yield;　under　moderate　earthquakes,　WRBs　will　yield　and　be　destroyed　to　stop　functioning　but　without　affecting　the　damping　effect　of　the　upper　structure.　Additionally,　the　total　yield　shear　force　provided　by　LRBs　is　proposed　to　be　close　to　the　standard　value　of　wind　load.
