To　improve　the　seismic　performance　of　the　multi-story　and　high　rise　frame　structure,　three　kinds　of　vibration　isolation　schemes　were　proposed　in　this　paper　based　on　the　energy　dissipation　technique　of　BRB　(buckling-restrained　brace,　BRB).　Taking　a　typical　multi-story　and　high　rise　frame-bent　structure　with　braces　as　an　example,　the　nonlinear　finite　element　analysis　was　carried　out　to　quantify　the　effect　of　these　schemes.　The　research　results　show　that　all　these　schemes　significantly　improve　the　distribution　of　storey　drift　angle　and　seismic　performance　of　the　structure,　and　in　which,　the　scheme　of　reduced　stiffness　achieved　excellent　performance　both　in　economy　and　security.　Verification　of　the　model　was　carried　out　by　a　cyclic　loading　experiment　of　1:10　models　of　the　frame-bent　structure　with　braces　and　satisfactory　agreement　was　obtained.　©　2016,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
