Development of deflection equations using moment-curvature relationships for concrete beam reinforced with fiber reinforced polymer (FRP) rebars
Over the past two decades, fiber-reinforced polymers (FRPs) have gradually gained wide acceptance in civil engineering applications due to their unique advantages including their high strength to weight ratio and excellent corrosion resistance. Whenever FRPs are used as structural reinforcement, deflections are an important consideration. Therefore, it is important to study the deflection of fiber reinforced concrete structures. This study developed analytical models to calculate such deflections using trilinear moment-curvature relationship. This relationship has three distinct points, viz: pre-cracking, post-cracking, and ultimate state point. These points are considered for evaluation of the deflections. The analytical model is compared with literature data, Bischoff’s, and ACI model for verification purposes. It was found to correlate well with the literature data and compared reasonably with other methods. Finally, a practical application of the model is also provided.
