Load-Deflection Analysis of FRP Reinforced Concrete Flexural Members

This paper is devoted to the deformability investigation of concrete flexural members reinforced with fiber-reinforced polymer (FRP) rebars. The analysis is carried out both theoretically, by means of a general procedure derived from a cracking analysis founded on slip and bond stresses, and experimentally, by means of flexural tests on aramid FRP reinforced concrete beams. Predictions of the general procedure are compared with both those furnished by models usually adopted for the analysis of FRP reinforced concrete structures and available experimental results. Finally, results of comparisons are discussed to demonstrate the effectiveness of model predictions and their applicability for design purposes.
