In this article, a model recently published by the authors is applied for the calculation of the axial resistance of centrically loaded fiber-reinforced plastic-confined rectangular concrete columns. The calculated results of our model agree well with the experimental data found in the literature. It is shown that the stiffness of the confinement has a much stronger effect on the strength than for the case of circular cross sections. Based on the numerical results, a simplified model is introduced which can be used in engineering practice.
