Split Hopkinson technique has been developed to test the strength of common concrete and steel fiber reinforced concrete under dynamic tensile loading. The result shows that the dynamic strength enhancement of concrete is strongly reinforced by the fiber. But for common concrete, the base of compressive strength seems to show little effect on the tensile strength at dynamic loading. The experimental results also show that the resistance to tensile fracture of steel fiber reinforced concrete for c100-mix is higher than this of c40-mix.
