To　study　the　axial　compressive　behavior　of　short　composite-sectioned　high　strength　concrete　filled　steel　tubular　(CSCFT)　columns,　3　groups　of　totally　23　specimens　were　tested　under　axial　compressive　loading　and　the　non-linear　finite　element　analysis　of　one　specimen　was　performed.　Test　results　indicate　that　the　failure　mode　of　all　the　specimens　were　similar,　i.e.,　the　square　steel　tube　buckles　outwards,　the　concrete　between　the　circular　steel　tube　and　the　square　steel　tube　is　loosened　and　partially　crushed.　At　the　end　of　test　the　longitudinal　strain　of　specimens　reach　0.09~0.11.　The　specimens　can　still　take　about　70%　of　the　peak　vertical　load.　The　calculated　compressive　stiffness　is　approximately　83.6%　of　the　average　measured　values.　The　calculated　axial　compressive　strength　of　the　specimens,　assuming　that　the　circular　tube　provides　lateral　confinement　to　the　core　concrete,　and　the　square　tube　provides　compressive　strength　only,　agrees　well　with　the　test　results.　The　axial　compressive　load-longitudinal　strain　curve　and　the　failure　procedure　obtained　by　the　nonlinear　finite　element　analysis　has　good　agreement　with　those　obtained　by　the　test.
