title = "Behaviour of fibre-reinforced concrete beams with different reinforcement ratios",
abstract = "The use of steel fibres in structural reinforced concrete is increasingly becoming implemented in design codes. Fibres are known to have an influence on the cracking process, and thereby on the material (concrete) toughness. However, when fibres are used in beams, which include a relatively small amount of conventional flexural reinforcement, their effect can be localized in a limited part of the beam. Such localization may lead to a reduction of ductility rather than to its increase, as observed in a previous study of high strength concrete beams, with and without fibres. This paper presents flexural tests with normal strength fibre-reinforced concrete beams with reinforcement ratios that varied between 0.15% and 3.3%. Measurements included the curvature at different points along the beam, as well as the load and the mid-span deflection. The results show the effects of adding steel fibres on the flexural behavior, especially the local influence on the tension rebars at low reinforcement ratios.",
