Shear capacity of RC beam/column member with self compacting high strength concrete and high strength steel was investigated. The following results were obtained; the increase of concrete compressive strength scarcely affects shear capacity carried by concrete in higher ranges than 50MPa, size effect became remarkable, and that concrete strength should be also carefully considered to use high strength steel as stirrup effectively. The experimental results and the current design equation were compared, and FE analyses based on a shear transfer constitutive model considering the fracture phase of high strength concrete were carried out. It was verified that the proposed analytical method could evaluate shear capacity and deformation of RC beams with high strength materials.
