The　flat　concrete　filled　steel　tube　column　with　gambrel　has　been　used　in　the　curtain　wall　column　at　the　project　of　Dalian　International　Conference　Center.　Two　1　/3　scaled　specimens　were　designed　according　to　the　actual　project　and　tested　under　the　cyclic　loading.　One　of　the　specimens　was　the　ordinary　flat　concrete　filled　steel　tube　column　with　gambrel　and　the　other　was　the　flat　multi　-　cavity　concrete　filled　steel　tube　column　with　gambrel.　Bearing　capacity,　stiffness,　ductility　and　failure　characters　of　the　two　specimens　were　analyzed　and　compared.　The　results　show　that:　compared　with　the　flat　ordinary　concrete　filled　steel　tube　column　with　gambrel　,　the　flat　multi　-　cavity　concrete　filled　steel　tube　column　with　gambrel　has　higher　seismic　energy　dissipation　capacity　and　better　ductility,　and　it　can　be　applied　in　the　practical　engineering　project.
