Influence of Plate Modulus of Elasticity on the Structural Behaviour of Fibre Reinforced Plastic Plated Reinforced Concrete Beams

摘要

This paper identifies and addresses all the possible modes of failure which are likely to occur in connection with reinforced concrete beams strengthened with externally bonded steel/FRP plates glued to their soffit (tension side). Furthermore, this paper presents an analytical study which explains the effect of variations in the magnitude of the modulus of elasticity, E{sub}p, for the external Fibre Reinforced Plastic (FRP) plates bonded to the tension side of reinforced concrete beams, on the modes of failure for the composite beam with a detailed account of section stress and strain distributions, plus the resulting beam flexural load capacities.
