Abstract
It is usually observed that RC deep beams, where the entire member becomes D-region, fail by the localized compressive failure of concrete. In this study, the utilization of the concept on localized compressive failure in formulation of the material model of concrete, based on the parameters such as the localized compressive failure length, Lp, and the compressive fracture energy, GFc, is performed. By incorporating the proposed compressive stress-strain relationship to the 2 simplified analytical models, the lattice model and Mander's truss model, the satisfactory predictions on the shear behavior of RC deep beams with and without transverse reinforcement are obtained.
