Characteristics and Influencing Factors of Deflection in Concrete Beams Reinforced with FRP Bars

Abstract:

The low modulus of elasticity of the FRP bars and their non-yielding characteristics results in large deflection and wide cracks in concrete beams reinforced with FRP bars. Consequently, in many cases, serviceability requirements may govern the design of such members. Based on the experiment studies of 5 beams of 2 groups under vertical loads at three-dividing point, the characteristics of FRP reinforced concrete beams was researched. At the same time, the experimental beams are modeled and the influencing factors of deflection of FRP bars concrete beam are analyzed using ANSYS program.
