Abstract:Recently, deterioration of reinforced concrete structures has been an issue of concern, such that repair methods and repair practice have been studied by many organizations. In this study the flexural behavior of FRP reinforced concrete beams (FRPC beams) was studied. The experimental values of the tensile stress in the main reinforcement, the concrete crack width, and the center displacement of FRPC beam agreed well with the calculated values. The flexural behavior of repaired reinforced concrete beams (RRC beams) using FRP and polymer mortar was studied. The results showed that tensile stress in the main reinforcement, the concrete crack width, and the center displacement of the beam were decreased after repair work. The elastic theory of reinforced concrete was still effective on the repaired beam. The values of tensile stress in the main reinforcement, and the center displacement of the beam could be calculated.
