Comparison of stress-strain model of FRP-confined concrete in circular and square section

Structural reinforcing by the use of fibre-reinforced polymer (FRP) composites has found increasingly wide applications in civil engineering because of their high strength-to-weight ratio and excellent corrosion resistance. Reliable design of these structural elements requires a clear understanding...

description Structural reinforcing by the use of fibre-reinforced polymer (FRP) composites has found increasingly wide applications in civil engineering because of their high strength-to-weight ratio and excellent corrosion resistance. Reliable design of these structural elements requires a clear understanding and accurate modelling of the stress-strain behaviour of FRP-confined concrete. Therefore, to model the mechanical behaviour of FRP-confined concrete, peak strength and ultimate strain are necessary to be defined. This paper presents a review of nine circular section models and eight square section models developed to predict the ultimate axial stress and ultimate axial strain of FRP-confined concrete.
