Extensive studies have been conducted to understand the catastrophic shear behavior of reinforced concrete beams, which is a complex phenomenon that depends on many parameters. To facilitate the analysis of RC beams, this paper presents a novel analysis method for predicting the shear strength of beams of normal proportions. In this analysis, for getting levels of yielding and ultimate loads, a parallel determinate truss was modeled. To evaluate the proposed truss model’s validity and applicability, the analysis procedure is examined against three different RC beams, and the results are compared with experimental data available from the literature. It finds that all experimental observations from the literature accord with the predicted shear strength values. This study shows that the shear strength of reinforced concrete elements subjected to shear can be determined by applying the truss analogy approach appropriately.
