Abstract

Concrete beams reinforced with glass fiber-reinforced polymer (GFRP) bars exhibit large deflections and crack widths compared with concrete members reinforced with conventional steel. Current design methods for predicting deflections under the loading and crack widths developed for concrete structures reinforced with steel may not be used for concrete structures reinforced with GFRP, but some of parameters will be used. Based on this paper research work and past studies, a theoretical correlation for predicting crack width was proposed. Experimental results are focused in examining the two sets of concrete beams with different percent of reinforcement using the GFRP bars. In this case the compare parameters are deflections, cracks, and bearing capacity using the analytical and experimental results. The beams were tested under a static load to examine the effects of the reinforcement ratio and compressive strength of concrete on cracking, deflection, ultimate capacity, and modes of failure.
