The objective of this paper is to propose an analytical method to predict the strength of reinforced concrete beams in shear. Kupfer proposed a truss model where the compatibility of strains and the equilibrium of stresses of the cracked concrete and shear reinforcement were used taking into account the effect of aggregate interlocking. Based on Kufer's model, an analytical method with incremental form was newly developed to classify the shear failure modes in this study. The effective compressive strength of concrete which was to be applied to high strength concrete was also proposed. The shear strength theoretically predicted by the proposed method was compared with available experimental data and the better results than other methods was obtained.
