Abstract:During the last 4 years a large testing program has been carried out in order to investigate the shear capacity of concrete beams containing longitudinal reinforcement and steel fibers. The results of this research program are presented here and compared with calculated values. For the calculations two models were used: the model proposed by RILEM TC 162-TDF and the model of Imam which is originally derived from a formula proposed by Bazant and Sun. The results of this comparison indicate that the RILEM method is a conservative approach. Especially the contribution of the stirrups and the influence of the shear span to depth ratio are underestimated. In the formula of Imam the contribution of the stirrups is calculated in the same way as in the RILEM method and consequently underestimated. However, for SFRC beams containing longitudinal reinforcement but without stirrups the correlation between experimental results and values calculated with the formula of Imam is fairly good.
