Use of high strength concrete and steel in steel reinforced concrete (SRC) columns is expected to improve the earthquake-resistance properties. This paper describes the test results on SRC columns under concentric compressive loading. The variables were specified compressive strength of concrete, Fc, tensile strength of steel, shape of steel, hoop ratio, Pw, and yield strength of hoops, wσy. The main results could be derived as follows; (1) The measured ultimate compressive strength of SRC columns had been increased by use of high strength concrete and high strength steel. (2) The superposed strength method was useful when ultimate compressive strength of SRC columns using high strength concrete and steel was calculated. (3) When the value of Pw・wσy was larger, the ductility after reaching the maximum strength was become larger.
