This paper presents the results of a nonlinear Finite Element (FE) analysis conducted on Reinforced circular columns strengthened with Carbon fibre reinforced polymer (CFRP) sheets. The main objective of this paper is to analyse the CFRP strengthened columns through non-linear finite element modeling and compare it with the experimental results.Modeling the complex behaviour of reinforced concrete, which is both non-homogeneous and anisotropic, is a difficult confront in the finite element analysis of civil engineering structures. The accuracy and convergence of the solution depends on factors such as mesh density, constitutive properties of concrete, convergence criteria and tolerance values etc., Three-dimensional finite element models were developed using a smeared crack approach for concrete and three dimensional layered elements for the CFRP composites. The results obtained through finite element analysis show good agreement with the test results.
