A　new　vertical　isolator　designed　by　disk　spring,　called　combined　disk　spring　bearing　(DSB),　is　introduced　in　this　paper.　DSB　is　composed　of　one　main　disk　spring　bearing　and　eight　secondary　disk　spring　bearings.　Performance　tests　show　that　DSB　had　good　property　of　variable　vertical　stiffness　and　high　vertical　damping.　Then,　the　effectiveness　of　DSB　vertical　base-isolated　devices　in　reducing　structural　responses　caused　by　earthquakes　through　a　series　of　1/2　scale　shaking　table　tests.　are　conducted　to　study　the　seismic　responses　of　the　and　the　DSB　vertical-isolated　system.　Compared　with　the　fixed-base　system,　experimental　results　show　that　the　DSB　vertical-isolated　system　can　isolate　vertical　earthquake　energy　remarkably.　Large　displacement　of　the　DSB　vertical-isolated　system　occurred　on　the　isolation　layer,　and　the　inter-story　deformation　of　the　superstructure　changed　slightly.　The　acceleration　responses　of　DSB　vertical-isolated　system　decreased　more　than　50%　and　the　displacement　responses　decreased　more　than　40%　at　0.4g　PGA,　which　confirmed　that　DSB　could　decrease　the　seismic　responses　effectively.　©　(2012)　Trans　Tech　Publications.
