Abstract
Design of RC beams with longitudinal reinforcement made of steel bars has adopted the philosophy of Under-Reinforced Design. But, Concrete Beams with FRP longitudinal bars need a reconsideration of this philosophy. The large strength of FRP bars and low strength of concrete obviates Over-Reinforced Design. By suitably increasing the amount of FRP longitudinal bars, it is possible to enhance the deformability of the FRP-reinforced beams. While Limit State Method of design will be applicable still, the partial safety factors on loads and on materials need to be adopted after due experimental studies.
