Concrete-filled　steel　tubular　(CFST)　hybrid　columns　are　composed　of　CFST　members　and　connected　by　reinforced　concrete　(RC)　plates.　Experimental　study　on　seven　axially-loaded　CFST　hybrid　stub　columns　with　different　wall　thickness　of　steel　tube　and　thickness　of　RC　plate　was　carried　out.　The　failure　modes,　compression　deformation,　and　strain　process　were　obtained.　The　effect　of　wall　thickness　of　steel　tube　and　thickness　of　RC　plate　on　the　ultimate　load-carrying　capacity　was　also　analyzed.　The　test　results　show　that　the　responses　of　CFST　hybrid　stub　columns　can　be　divided　into　the　elastic　state,　elasto-plastic　stage,　plastic　development　stage.　The　failure　of　an　axially　loaded　CFST　hybrid　stub　column　is　due　to　the　crushing　of　RC　plate,　while　the　CFST　member　does　not　reach　its　ultimate　resistance.　A　reduction　coefficient　K,　related　to　the　confinement　coefficient,　is　introduced　to　account　for　the　contribution　of　CFST　members　to　the　ultimate　load-carrying　capacity　of　the　CFST　hybrid　stub　columns.　Based　on　the　collected　existing　test　date　of　axially　loaded　CFST　hybrid　stub　columns,　an　empirical　calculation　formula　for　the　reduction　coefficient　K　is　presented.　Comparison　study　indicates　that　the　predicted　load-carrying　capacity　of　axially-loaded　CFST　hybrid　stub　column　by　the　calculation　methods　presented　in　this　paper　are　close　to　the　test　results.　©　2016,　Editorial　Office　of　Journal　of　Building　Structures.　All　right　reserved.
