- Abstract
- This paper reports on analytical investigations on the development of shear strength expression applicable to reinforced concrete (RC) deep beams. The shear strength of RC deep beams provided with shear reinforcement incorporating size dependent parameters has been studied. The development of the shear strength expression is based on the shear transfer mechanism of deep beams idealized through a refined strut-and-tie model according to the modified Bazant’s size effect law and a large experimental data. The accuracy of the proposed expression has been validated with other existing models including the ACI Strut-and-Tie model. By incorporating various influencing parameters such as compressive strength of concrete, shear span-to-depth ratio, effective depth of beam and percentage of flexural steel reinforcement, the estimation of the shear strength of RC deep beams has been observed to be relatively better.
