This research aims to ductility demand survey on concrete column strengthened with CFRP laminates. The behavior of concrete, FRP and reinforcements have been implemented in software computer program. Then, the analytical results has verified after considering and comparing with experimental outcomes. After calibration the analytical results with experimental results done by Ozcan et al, the effect of length and thickness of CFRP wrapping on displacement ductility and rotational capacity of column has been considered. In this way, the columns without FRP and with one and two-layer FRP wrapping using different lengths have been modeled by ABAQUS as finite elements software. For each column the CFRP material strains in different location, has been measured. The base shear-displacement curve at the end of column and the displacement ductility of columns has been examined. Moreover, the section curvature in different location across the length of column and also moment at the end of column has been obtained. The obtained results have been compared with some analytical equations. Then the length of plastic hinge and the created rotation at the end of column have been calculated and the influence of length and thickness of CFRP wrapping have also been examined on rotational capacity of the column. In this study also the acceptance criteria for nonlinear procedures-reinforced concrete columns wrapping with CFRP for different length and thickness of wrapping has been investigated. In addition, the maximum plastic rotation angle of columns has been calculated.
