Buildings and bridges which collapsed in recent earthquakes highlighted the need for the retrofitting old infrastructure. The need arises because of the inadequate lateral strength and ductility of old structures which were primarily designed to transfer dead load and live loads. The availability of advanced composite materials and its innovative applications in civil engineering is relatively new. The interest in using composite material for confinement of new or existing concrete columns, has led to the attention of researchers and of the industry on its applications in civil engineering. For design of any member, along with the other properties, its stress-strain behaviour is of utmost importance. A detailed study of different stress-strain models is presented in this paper.
