摘要：

This study proposes a model for calculating the average width of cracks in reinforced concrete (RC) elements using non metallic reinforcement bars (FRP). This model has already been applied to the case of steel reinforcing bars successfully.. It considers the influence of the percentage of reinforcement and the concrete strength. It emphasizes how the mechanical features of FRP (fiber reinforced polymer) bars, and particularly their modulus of elasticity, can affect the crack width. The model is validated with experimental results available in the literature. An example of its application for the calculation of the crack width is shown.
