Steel fibre-reinforced concrete (SFRC) has shown better performance behaviour with respect to the post-crack strength and in restricting the crack width and its propagation. Studies on behaviour of SFRC under repeated loading are a significant work. Behaviour of reinforced concrete structures during ground excitations in the form of earthquake forces could be significantly improved by addition of steel fibres in suitable dosage. Fibre type, aspect ratio, and dosage of fibres significantly influence the behaviour of steel fibre-reinforced concrete. Here, the work carried by various researchers with respect to the studies on the behaviour of SFRC under monotonic and cyclic stress in compression is presented. An experimental investigation on stress–strain characteristics of SFRC under monotonic loading in compression was carried, comprising M20 grade concrete, hooked-end steel fibres (l = 50 mm, diameter = 1 mm), and varying fibre dosages of 1.0, 1.25, 1.5, and 1.75% by volume of concrete. The stress–strain characteristics arrived based on the above experimental studies were compared with theoretical stress–strain characteristics, based on the equations proposed in literature. This served in understanding the behaviour of SFRC with respect to their stress–strain characteristics using experimental studies and by theoretical models, and analyse the extent of agreement and acceptance.
