Abstract

This paper reports on development of a refined strut-and-tie model for determining the size de- pendent shear strength of reinforced concrete deep beams. The predicted model is based on Siao’s Model for size independent shear strength of deep beams, Modified Bazant’s size effect law and the experimental data re- ported by several researchers. The proposed model predicts the shear strength of deep beams as a function of compressive strength of concrete, longitudinal and web reinforcements steel ratios, shear span-to-depth ratio and the effective depth of beam.
