Abstract
The design of many structural elements requires the use of deep concrete beams. However, their geometrical proportions make these beams viable to total shear failure without ample warning. Available researches have shown that the employment of steel fibers in concrete improves the structural performance of deep beams. However, validated capacity prediction models that facilitate the design for these beams are scarce in the approachable references. Several investigators have been suggesting predictive formulae for the evaluation of the shear strength of steel fiber reinforced concrete (SFRC) beams. In the current study, an equation that can predict the shear capacity of SFRC deep beams was derived in terms of compressive strength of concrete, shear span, beam sectional dimensions, and fiber factor. The derived equation compares fairly well with the authors’ experimental data and the data available in the literature.
