Strengthening of RC columns through lateral confinement provided by external fiber-reinforced polymer jackets (or wraps) has become an increasingly popular technique over the past decade. An important application of fiber-reinforced polymer composites is to provide confinement to reinforced concrete (RC) columns to enhance their load-carrying capacity. In this paper, non-linear finite element modelling is carried out on the slender reinforced concrete columns wrapped with CFRP composite with different compressive concrete strengths that are tested under eccentric monotonic loading. The results of the finite element analysis correlate well with the results of the tests. In this study, the influence of CFRP thickness, concrete compressive strength, and Slenderness on the performance of eccentrically loaded slender reinforced concrete columns confined with CFRP is investigated.
