Five-Phase Sphere Model for Elastic Modulus of FRP-Confined Concrete

Abstract:

Based on the four-phase sphere model, a five-phase sphere model predicting the elastic modulus of FRP-confined concrete was built up, by considering the effect of FRP sheet. The model can describe the elastic modulus of the FRP, the stirrup ratio, the aggregate volume fraction, the aggregate size and the interfacial transition zone (ITZ), et al. on the development of the elastic modulus of FRP-confined concrete with age. By comparing with the experimental data, the five-phase sphere model evaluates the tests well
