Experimental Study on Flexural Deformation Behavior of Concrete Beams Reinforced with GFRP Bars
In this paper, the deflection of GFRP bars reinforced beams with different reinforcement ratio was studied, To research deflection of GFRP reinforced beam, four specimen beams were test under a four-point static load. The results indicate that deflection history of GFRP bar reinforced concrete beam is different with steel reinforced concrete’s, which has two stages: the linear part before crack and linear part after crack. The ultimate deflection decreases with the increase of reinforcement ratio.
