Unified Shear Strength Model for Reinforced Concrete Beams—Part II: Verification and Simplified Method

This study integrates two previously-developed shear strength models for reinforced concrete (RC) slender beams and deep beams in order to develop a unified shear strength model. The models address the transition of shear failure mechanism according to the shear span-to-depth ratio. The unified model, which is applicable to both slender and deep beams with and without shear reinforcement, was verified by comparisons with existing experimental results. The comparisons showed that the proposed model predicts the shear strength of concrete beams better than current design methods for a wide range of values of design parameters. Based on the proposed strength model and the test results, a simplified design equation was developed that can predict the shear strength of RC beams both accurately and conservatively.
