Assuming reflection in design, the quantitative evaluation of tensile ductility of steel fiber reinforced concrete (design strength 30-60 MPa) containing 1.0% steel fiber with hooks at the ends was investigated. The method for evaluating the lower limit management value of tensile ductility of concrete in structure was proposed by setting the reduction factor based on the results of investigation of quality variation during actual manufacturing at a precast factory and the distribution of steel fibers within structure member. The tensile ductility evaluated by the proposed method was on the safe side compared to test results during actual manufacturing.
