| 要旨 | This paper describes the diagonal cracking shear behavior of reinforced high-strength concrete (HSC) members without web reinforcement. It was found that the diagonal cracking shear strength of HSC is governed by the ratio of uniaxial compressive strength to tensile strength (DN) of the concrete relative to that of the aggregate. As the DN of concrete exceeded that of the aggregate, diagonal cracking shear strength decreased due to the smooth fracture surface and brittleness. Based on the DNs of concrete and aggregate, definitions for concrete strength regions were proposed. |
