Abstract
In this study, the FRP-confined concrete models for prismatic members given in the ACI440.2R-08 and Turkish Earthquake Code (TEC2007) are compared with the experimental data taken from the literature. It is found that TEC2007 assumes only hardening behavior for concrete strengthened with FRP. Although ACI440.2R-08 assumes a hardening and softening behavior depending on the confinement-effectiveness, the limit separating the hardening and softening must be improved to predict the behavior well. The assumptions in these codes cannot predict the post-peak region of force-deformation curves because of the high factor of safeties. It is essential to understand the degree of confinement, confinement effectiveness and the resulting stress-strain relationship of a concrete strengthened with FRP.
