In　this　paper,　axial　compressive　loading　test　and　non-linear　finite　element　analysis　of　10　short　composite-sectioned　concrete　filled　steel　tubular　column　specimens　are　introduced.　The　test　results　indicate　that　the　failure　modes　of　all　the　specimens　are　similar,　the　specimens　have　high　axial　compressive　strength　and　large　deformation　capacity.　The　calculated　axial　compressive　strength　of　the　specimens,　assuming　that　the　circle　steel　tube　provides　the　lateral　confinement　to　the　core　concrete　and　the　square　steel　tube　provides　compressive　strength　without　contributing　lateral　confinement　to　the　concrete,　has　good　agreement　with　the　measured　strength.　The　vertical　load-strain　curves,　the　axial　compressive　strength　and　the　failure　mode　obtained　by　the　non-linear　finite　element　analysis　of　specimens　have　good　agreement　with　the　test　results.
