A bending test program on the series of RC deep beams with the effective depth, d, of 200, 400 and 600 mm has been performed. The transverse reinforcement ratio was va~ied from 0.0, 0.4 to 0.8 percent. The distribution of the local strains inside specimens, both of concrete and remforcement, has been measured. The test results confirm the localized compressive failure of concrete in the deep beams. Subsequently, the lo- calized failure volume, Vp, and the fracture energy, G&, of the concrete which locally failed in compression of each beam specimen have been evaluated. Finally, the concepts of localized compressive failure of concrete have been incorporated in the analysis of deep beam using Lattice model and the comparison between the ex- perimental and analytical results has been done.
