Summary:This paper presents the results of an experimental investigation of the axial behavior of small-scale circular and square plain concrete specimens and large-scale circular and square reinforced concrete columns confined with fiber reinforced polymer (FRP) composite jackets, subject to monotonic, concentric axial loads. Improvements in the axial load-carrying and deformation capacities of FRP jacketed concrete members over unjacketed members are reported. Factors influencing the axial stress-strain behavior of FRP confined concrete, such as transverse dilation and effectively confined regions and their relationship to jacket properties, are identified and discussed. Factors necessary to calibrate in situ jacket behavior and reported or measured FRP material properties are proposed and their interrelationships discussed.
