Fibre Reinforced Polymer (FRP) materials have been widely applied in construction and structural rehabilitation due to their high strength, stiffness-to-weight ratio, high corrosion resistance, the ability to form and to shape to the existing structure, and the application process which is relatively fast and easy. Many models and standards are suggested for estimating strength enhancement from FRP jacket but, there is still lacking to identify adequately accurate model to use in design purpose. Most of these models were calibrated by limited data. This paper provides an evaluation and numerical analysis of the previously published models that predict the axial strength and strain of circular reinforced concrete column confined with FRP. The goal of this research is to find a new approach, which will be based on analytical, numerical simulation and experimental study, for the formulation of strength enhancement of FRP confined concrete columns. It provides possible directions for safety design in accordance with Euro-code.
