One important application of fibre reinforced polymer (FRP) composites in the retrofit of reinforced concrete (RC) structures is to provide confinement to columns for enhanced strength and ductility. As a result, many theoretical and experimental studies have been carried out on the compressive behaviour of FRP-confined concrete. This paper provides a critical review of existing studies on this subject, with the emphasis being on the revelation of the fundamental behaviour of FRP-confined concrete and the modelling of this behaviour. Although the paper is explicitly limited to concrete confined with FRP jackets in which the fibres are oriented only or predominantly in the hoop direction, many of the observations made in this paper are also applicable or relevant to concrete confined with FRP jackets with a significant axial stiffness, as found in concrete-filled FRP tubes as new columns.
