Abstract:
An experimental and theoretical comparison between flexural behaviors of concrete beams reinforced with fiber reinforced plastic (FRP) reinforcing bars and identical conventionally reinforced ones was investigated. This comparison was made in terms of cracking behavior load-carrying capacities and modes of failure, load-deflection response, flexural rigidity, and strain distribution. The results indicated that perfect bond exists between FRP reinforcing bars and the surrounding concrete. They further show that ACI Code formulas for predicting deflection response, cracking-ultimate moments, and cracked-effective moments of inertia can easily be adapted for modeling the flexural behavior of concrete beams reinforced with FRP reinforcing bars if appropriate modijcations are made.
