Abstract:The present paper is devoted to the analysis of the behaviour of high performance concrete structures made with members reinforced with Fiber Reinforced Polymer (FRP) rebars. Models usually adopted for the evaluation of the deformability of steel reinforced concrete structures are described and their use for the analysis of FRP reinforced concrete structures is discussed. A theoretical model, developed taking into account both the real behaviour of materials and the interaction between the reinforcement and the concrete matrix is, thus, used to determine typical quantities that characterize the serviceability of reinforced concrete structures (moment-curvature and load-deflection diagrams). A large numerical investigation has been carried out in order to evidence the influence of predominating geometrical and mechanical parameters on the serviceability behaviour of FRP reinforced concrete beams. Finally, results of an experimental analysis, carried out by flexural tests on concrete beams reinforced with Aramidic Fiber Reinforced Polymer (AFRP) rebars, are described and a comparison between previsions of models and the experimental results has been made.
