A new hypothesis is proposed for the shear cracking mechanism in reinforced concrets beams without web reinforcement.
The hypothesis results from an analytical approach based on the observation that flexural-shear cracking results from a severe localization of internal stress after the onset of flexural cracking. This local stress concentration is associated with the nature of bond and the development of arch action.
Analytical expressions are developed for predicting shear cracking loads and positions.
