PROGRESS IN STUDIES OF THE CONSTITUTIVE MODEL OF FRP-CONFINED CONCRETE COLUMNS

  • This paper reviews the latest progress in studies of the constitutive models of the FRP(fiber reinforced polymer)-confined concrete,and analyzes their theoretical basis, the characteristics and the problems of existing models, focusing on the axial compressive strength and deformation, the failure mechanism of the FRP-confined concrete, and the main factors affecting the constitutive models, such as the FRP restraint stress and the actual strain at the failure state. A basic framework for comparative analysis of constitutive models in future is suggested.
