As　an　advancing　isolation　technology,　the　first-floor　isolated　structure　can　take　full　use　of　the　first-floor　space,　and　has　been　promoted　in　southern　China　gradually.　To　study　the　isolation　effect　of　the　first-floor　isolated　structure　and　to　improve　the　damping　rate　of　it,　a　seven-story　structural　model　with　laminated　rubber　bearings　and　metallic　dampers　installed　on　the　top　of　first-floor　columns　was　studied　by　shaking　table　tests　and　finite　element　analysis　using　SAP2000　API.　The　results　of　the　tests　and　analysis　show　that　the　isolation　technology　with　metallic　dampers　can　reduce　the　seismic　response　of　the　upper　structure　significantly.
