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.
