Abstract
A combined experimental and theoretical investigation into the compressive behaviour of CFRP- and SFRP-confined concrete is presented in this thesis. The experimental investigation included testing of small-scale unreinforced CFRP- and SFRP-confined concrete cylinders under axial compression. Fundamental aspects of compression behaviours such as failure mode, ultimate strength, ultimate strain, stress-strain response, ductility enhancement were closely examined. The theoretical investigation included performance assessment of some existing empirical, analytical and design code confinement. Modification to one of the existing models is proposed. The new model provided more accurate predictions of the ultimate strength, ultimate axial strain and stress-strain response of FRP-confined concrete Furthermore, the Drucker-Prager (DP) plasticity model parameters were derived and implemented in numerical Finite Element analyses to simulate the behaviour of FRP-confined concrete. It has been found that the DP model can give close predictions of confined concrete compressive behaviour should accurate material parameters be defined.
