dc.description.abstractFibre reinforced concrete (FRC) offers an improved resistance to cracking and crack propagation, which leads to increased strength and toughness in flexure. As there is a lack of understanding of structural behaviour of FRC,this paper reports a study on the influence of fibres on the behaviour of flexural members, and it focuses on a partial-interaction structural mechanics model for the deflection calculation of concrete beams reinforced with steel or FRP bars and fibres. For this, a model is developed to incorporate fibres into both tension and compression regions in generating moment-rotation response and also on crack formation and the tension-stiffening mehanism. For calibrating these models an experimental study on the bond-slip relationship between FRP bars and fibre concrete was required for the tension stiffening analysis; and an experimental study on the slip-crack width relationship between fibres and concrete required for the moment-rotation model. The moment-rotation and tension stiffening models were then used to obtain the load deflection (P-Δ) response through integration of discrete rotations at the determined crack locations throughout the member. The theoretical load-deflection responses are compared to the experimental results, showing very good correlation for the ultimate flexural capacity and the ductility of PVA fibre reinforced concrete members.-
