Abstract: This paper reports, a new analytical expression is proposed for predicting the shear strength of RC deep beams using Strut-and-Tie model (STM). The proposed expression is compared with some of the existing expression and ACI 318-14 code expression. The 111 deep beams specimen’s experimental data have been collected from the literature survey to find out the unknown parameters. The proposed expression encloses, concrete compressive strength, amount and arrangement of longitudinal and web reinforcement, shear span-to-depth ratio and effective depth. The results indicates that the proposed expression is one of the best fitting expression to predict the shear strength of variety of RC deep beams.
Keywords: Deep Beams, Strut-and-tie Model, Shear Strength, Shear Span-to-depth Ratio.
Scope of the Article: Numerical Modelling of Structures
