Modeling of compression softening is essential to predict the ultimate behavior of RC members. In this study, constitutive laws of concrete under compression-tension state are extended according to the concept of the fracture energy and the influence of compression softening on ultimate behavior of RC members failing in shear compression mode was examined. It was found that the ultimate strength and deformation strongly depended on compression softening, namely compression fracture energy. It was also found that the analytical results agreed well with experimental ones, when compression fracture energy of 40 N/mm was used for normal concrete with compressive strength of 20 MPa.
