This paper present results from effect of fiber volume fraction on direct shear property of steel fiber reinforced concrete(SFRC). Steel fiber with crimped end was used this work. Principal variable is fiber volume fraction; 0, 0.5, 1, 1.5, 2%, and aggregate size; 8, 13, 20mm. Specimen cross-sectional is 100 x 100 x 400mm. In order to induce the shear failure 2mm notch was sawed all around the specimen. Test result, there are little different between the aggregate size, and the improvements in shear strength of SFRC were more significant for 1% steel fiber volume fraction.
