<p>In many national codes of practice, the shear strength of reinforced concrete beams without web reinforcements is estimated using empirical equations developed from laboratory experimental findings. Such empirical expressions account for the dowel action of longitudinal tension steel reinforcement, aggregate interlocking, and uncracked concrete in flexural compression. The shear strength of the section near the support region increases due to a concentrated load close to the support. The shear strength enhancement near the support regions could be due to the direct transfer of loads to the support through a tied-arch mechanism. The conventional empirical expression cannot predict the enhancement of the shear strength of the section near the support. National codes recommend the shear enhancement accounting for the arch action. In this study, the shear enhancement factors proposed in <i>IS 456</i> and <i>EC2</i> have been reviewed and validated through 232 experimental test data on beams without web reinforcement. Further, the applicability of Sahoo’s shear strength expression for sections near supports has been analysed. The shear enhancement-based prediction has been found to result in highly conservative estimation for all three models. The conservatism increases with an increase in compressive strength of concrete. This study proposes a modification factor to account for the high compressive strength, which improves prediction accuracy.</p>
