In　order　to　improve　the　seismic　energy　dissipation　performance　of　concrete　filled　square　steel　tubular　(CFST)　columns,　the　structural　measure　about　puting　the　additional　energy　dissipation　plat　at　the　bottom　of　the　CFST　columns　where　bears　more　stress,　was　proposed.　Finite　element　anylsis　of　10　CFST　columns　with　different　structural　measure　were　performed　under　the　same　axial　compression,　selecting　the　thickness　and　height　of　the　energy　dissipation　plate　as　parameters.　On　the　basis　of　finite　element　anylasis,　this　paper,　which　obtained　load-displacement　curves　of　each　finite　element　model,　analyzed　and　compared　the　bearing　capacity　of　each　model.　The　results　show　that:　comparing　to　the　ordinary　CFST　columns,　the　columns　with　energy　dissipation　plat　show　better　about　bearing　capacity　and　seismic　performance,　the　height　of　the　energy　dissipation　has　a　significant　effect　on　bearing　capacity　but　the　thickness　has　less　impact.
