In this article, a new model for eccentrically loaded FRP-confined circular concrete columns is presented. The cross-section is built up by 2D finite elements (where the variation of the stresses and strains is 3D), and the concrete modeled by a confinement-sensitive (non-associated) material law. The numerical solution of this model showed agreement with the experimental results available in the literature. It is shown that the maximum axial stresses in the cross-section-despite of the big differences in the radial- and hoop confinement stresses-are about the same for concentric and eccentric loadings. It is also shown that the recommended stress-strain curves available in the literature may lead to non-conservative results for eccentric loading, and-based on our numerical calculations-new stress-strain curves are recommended.
