It is said that the concrete filled steel column, so called the composite column, possesses good strength and ideal ductility. However, its behavior under load is not clear enough at present. We made experiments to compare the effect of shear connectors with that of projections on steel plate for the simplest column under the axial load. During the axial loading, the authors gave impact on the specimens and measured induced elastic wave. Spectrum analysis of the elastic wave gave the information about composite action between concrete and steel. By these experiments the following were observed. The column with shear connectors had the highest rigidity, the one with projections the second and the one of flat steel the lowest. The strength was almost the same to the column with shear connectors and the one with projections. As for the ductility, the steel with projections was better than the one with shear connectors.
