The use of FRP bars to reinforce concrete structures is considered as one of the most prominent solution that may overcome the corrosion of reinforcing steel bars. However, in the case of FRP reinforced concrete, both the reinforcing and the reinforced materials are brittle. As a result, all failure modes of concrete members reinforced with FRP rebars are brittle. Ductility of structures with FRP reinforcements is much less than that of structures with steel reinforcements. This paper presents the flexural behavior of concrete beams reinforced with FRP rebars in comparison with that of one with steel reinforcing rebars. It is also focused on ductility increasing of FRP reinforcing concrete beams reinforced with confinement provided to the concrete in the compression zone.

The use of FRP bars to reinforce concrete structures is considered as one of the most prominent solution that may overcome the corrosion of reinforcing steel bars. However, the low modulus of elasticity of the FRP materials and their non-yielding characteristics results in large deflection and wide cracks in FRP reinforced concrete members. Consequently, in many case, serviceability requirements may govern the design criteria of such members. This study is focused on verifying equations of ACI 440.1R-01 and ISIS Canada design manual to predict deflections and crack widths. It is also focused on providing engineers and researchers a better understanding of the behavior of GRRP reinforced concrete beams.
