Shear Capacity of Concrete Beams Containing Longitudinal Reinforcement and Steel Fibers

Abstract

This paper presents results of a large testing program that has been carried out to investigate the shear capacity of concrete beams containing longitudinal reinforcement and steel fibers. Two models were used for the calculations: RILEM TC 162-TDF and the model Imam. The comparison results show that the RILEM model is a conservative approach, especially underestimating the contribution of the stirrups and the influence of the shear span to depth ratio. The Imam calculates the contribution of the stirrups in the same way as the RILEM. The Imam, however, is fairly good for SFRC beams containing longitudinal reinforcement but without stirrups.
