Use of high strength concrete, steel and hoops in steel reinforced concrete (SRC) columns with H-shaped steel is expected to improve the earthquake resistance properties. This paper describes the test results on SRC columns with shear span/depth ratio; 1.2, under constant axial force and cyclic lateral force. The variables were specified compressive strength of concrete, Fc, tensile strength of steel, axial load levels, n, and yield strength of hoops, w σ y. The main results could be derived as follows; (1) The measured ultimate shear strength of SRC columns had been increased by use of high strength concrete and high strength steel. (2) When the value of the product of hoop ratio, Pw, and yield strength of hoops, w σ y, was larger, the ductility after reaching the maximum strength was become larger. (3) The reduction factor for shear strength of SRC columns calculated according to the theory of plasticity have been required when high strength concrete and high strength steel are used.
