Minimum Reinforcement Ratio of Concrete Beams Reinforced with FRP Bars
Based on the non-linearity stress strain relation of concrete, the cracking moment of plain flexural concrete member is established, and the flexural capacity of concrete beams reinforced with FRP bars is also obtained under FRP rupture-controlled failure. To prevent FRP rupture failure upon concrete cracking, the minimum reinforcement ration should be derived from simplified calculation, which may provide some theoretic guidance on design and construction for concrete structure reinforced with FRP bars.
