Abstract

The results of a theoretical analysis of fiber-reinforced polymer (FRP) reinforced concrete (RC) flexural elements are reported in this paper A large database of RC specimens (beams and slabs) was analyzed including beams tested by the authors. The experimental load-deflection curves of these specimens were compared with the theoretical predictions based on the deflection model as suggested by ACI Committee 440. An appropriate modification in the ACI 440.1R method of calculating effective moment of inertia is proposed to predict deflection of concrete beams reinforced by any type of FRP bar. The modified expression provided consistent results and the predictions agreed well with the curvature and deflection data measured experimentally. The investigation also considered other available methods of deflection calculation. A comparison of the results showed the effectiveness of the suggested equation over these methods.
