This paper deals with the compressive strength and the deformation characteristics of reinforced concrete columns composed of concrete of different strength. The authors carried out the centrally loaded compression test varing the member composition, the ratio of tie hoop reinforcement, the compressive strength of concrete and the ratio of cross-sectional area of the shell to the core respectively. Also, the failure process and the relationship between the load and the deformation are studied. From these studies, the stress-strain relation formula of concrete and reinforcing bar are introduced, and the ultimate compressive strength formula of the composite columns which are in good agreement with the experimental value are proposed.
