In this paper the stress-strain behavior of concrete confined by various types of FRP in the form of spiral or sheet is discussed. An experimental investigation is described, in which the main parameters are fiber volume fraction, fiber stiffness modulus, fiber tensile strength and concrete strength. On the basis of the experimental results a model for stress-strain relation of concrete confined by FRP is developed which takes into account the linear elastic behavior of the FRP. The model, which will be useful in deformation analysis of FRP-concrete flexural members, utilizes an exponential equation for the ascending branch and a linear equation for the descending part. The confinement effect is expressed as a simple function of fiber volume fraction of confining FRP, its modulus of elasticity and compressive strength of unconfined concrete. A good agreement with experimental results is obtained.
