This paper proposes an analytical study to predict the flexural capacity of structure elements reinforced with glass fibre reinforced polymer (GFRP) bars. A nonlinear stress-strain curve of concrete is employed to consider the contribution of concrete under compression. The analytical calculation is validated against a published experiment, and the results are also compared to the ACI 440.1R-15 code. The results showed that the rupture modes predicted in the analytical study were comparable to those of the experiment, and the average ratio of flexural capacity calculated using Todeschini’s nonlinear curve to the experiment ranged from 0.78 to 0.86. Furthermore, flexural capacity obtained using nonlinear stress-strain curve of Todeschini for specimens with reinforcement ratios higher than the balanced reinforcement ratio performed better than that obtained using the ACI code.
