In　order　to　compare　mechanical　properties　of　special-shaped　multi-cell　concrete-filled　steel　tube　(CFST)　columns　with　different　construction　measures,　five　model　specimens　of　octagonal　special-shaped　multi-cell　CFST　columns　were　analyzed　by　finite　element　analysis　software　Abaqus.　On　the　basis　of　analysis,　the　seismic　performance　and　stress　variation　of　the　five　specimens　were　compared,　and　the　analysis　of　their　cost　performance　ratio　and　evaluation　of　the　rationality　of　the　different　construction　measures　were　also　made.　The　analysis　results　show　that　the　structural　measures　of　setting　cavity　plates,　vertical　ribs　and　angle　steels　in　steel　pipes　significantly　affect　seismic　capacity　of　special-shaped　multi-cell　CFST　columns,　but　that　of　setting　horizontal　ribs　do　not　because　the　seismic　performance　of　the　giant　columns　can　be　improved　by　setting　cavity　plate,　ribs,　and　so　on,　resulting　in　its　reasonable　cost　performance　ratio.　It　can　be　applied　in　actual　engineering　structures.　©,　2015,　Beijing　University　of　Technology.　All　right　reserved.
