Concrete beams reinforced with glass fiber-reinforced polymer bars exhibit large deflections and crack widths compared with concrete members reinforced with conventional steel. In this work, the current design methods for predicting deflections under loading and crack widths are developed using the same theory with some additional parameters. Based on the research work presented in this paper and past studies, a theoretical correlation for predicting the crack width and deflection is proposed by testing six concrete beams; specifically two sets are reinforced with different glass fiber-reinforced polymer of reinforcement ratios and one set is used as the control beam. The research objective is to analyze the behavior of the beams under loading and obtain the differences in their behavior in terms of the following parameters: deflections; cracks, and general bearing capacity.
