Abstract The current study has investigated the shear behavior of reinforced concrete T-beams. The scope of the study consisted of an experimental investigation and theoretical analysis. This experimental program comprised a total of six medium-scale reinforced concrete beam specimens tested to shear failure at the Reinforced Concrete Laboratory of the Structural Department of the Faculty of Engineering at Ain Shams University to investigate the modes of failure, the ultimate load capacity and the shear behavior of the reinforced concrete Tbeams. The deformation, crack width and the steel strain were examined. The six beam specimens included five T-section beam specimens and one control beam specimen with rectangular section. The key parameters considered in the experimental program were the flange width (Bƒ) and shear span-to- depth ratio (a/d). The theoretical (analytical) phase included different analytical approaches to predict the shear strength and behavior of the tested beam specimens. These analytical models used to predict the shear behavior of reinforced concrete T-beams included well-established shear theory, Strut and Tie model (STM) and simplified shear design equations. The predictions of the shear models were compared with the results of the experimental program. Based on the findings of the experimental and analytical investigations, conclusions were made |
