A Theoretical Analysis of Shear Failure of a Reinforced Self- Compacting Concrete Beam without Shear Reinforcement was Experimentally Validated

Abstract

Abstract: Failures linked with reinforced concrete include axial, flexural, shear, torsion, and deflection (as well as cracking in the case of RC as a material) beyond specified allowed limitations. Failure due to shear (including shear related with torsion) is the most severe and can occur with little or no notice. To prevent the brittle character of shear failure with little or no forewarning, an examination was conducted to determine the size effect, and the diagonal shear failure of reinforced concrete beams without stirrups was analysed in terms of the effective depth of the section. The test beams are made of two types of concrete: conventionally vibrated concrete and self-consolidating concrete, both having nominal compressive strengths of 30, 60, and 70 at 28 days. Given the limitations of the laboratory, three beam sizes with overall depths of 200, 300, and 500 mm, a set shear span to effective depth ratio (a/ d) of 3.50, and a constant tensile reinforcement content of 3% are utilised as test specimens. The experimental results were compared to the acceptable shear stress requirements of IS 456 and ACI 318. The size, concrete type, and concrete strength were determined to have a substantial influence on beam shear strength
