A nonlinear finite element model is developed for the analysis of an RCC (reinforced concrete column) confined by FRP (fiber - reinforced polymers) sheets and subjected to eccentric loading. A practical design of FRP confined concrete columns requires an accurate estimate of the performance enhancement due to the confinement mechanism under eccentric loading. Therefore, a confinement model is developed which relates the confined concrete strength with the unconfined concrete strength. In the present study, a 3-D finite element model is developed using the finite element software, ANSYS for the analysis of an FRP confined reinforced concrete circular column under axial and eccentric loading. The effects of four important parameters are studied in the present work: namely, the unconfined concrete strength, FRP thickness with different layer orientation, orthotropic properties of FRP and orientation of FRP fibers. The study focused on some interesting effects of these parameters on the confinement effectiveness of eccentrically loaded reinforced concrete columns. Many new results are generated which should be useful for future references.
