The quantitative evaluation of tensile ductility as a material property was studied, assuming the reflection in design of the superior ductility of steel fiber reinforced concrete with 0.5％ to 1.0％ by volume of steel fibers with hook geometry at both ends. From the experimental results on the effect of mix proportion conditions on tensile ductility, it was confirmed that tensile ductility can be generally evaluated based on the amount of steel fiber and compressive strength. Further, taking into account the effect of quality fluctuations in actual production, a quantitative evaluation method for tensile ductility assuming reflection in design was proposed.
