Dumbbell-shaped　section　is　often　used　in　concrete　filled　steel　tubular　(CFST)　arch　rib;　whereas　great　stress　is　likely　to　produce　cracks　in　the　weld　sealing　between　steel　tube　and　web　plates　when　concrete　is　filling　into　the　web　space.　Therefore　a　new　type　dumbbell　section　is　proposed,　in　which　instead　of　concrete　in　the　web　space　is　the　stiffening　H-shape　steels.　Analysis　indicates　that　the　possibility　of　broken　accident　is　very　small　because　no　concrete　will　fill　into　the　web　space　in　this　new　type　dumbbell　section.　Experimental　research　on　CFST　stubs　with　new　type　dumbbell　sections　subjected　to　axial　loads　are　carried　out.　Research　results　indicate　that　CFST　stubs　with　new　type　section　behaves　similarly　to　those　with　traditional　section　and　its　ultimate　load-carrying　capacity　can　be　estimated　with　the　same　methods.
