In this paper, a study on the ultimate axial strain of the fiber-reinforced polymer (FRP) confined concrete is presented. To this aim, a large database was assembled from the scientific literature including results from compression tests performed on over 450 FRP-confined concrete cylinders. The experimental data were then used to calibrate, through simply best-fit procedures, some of the most accredited predictive strain models available in the literature; the efficiency of the found relationships was then compared with that of the formulations proposed by other authors. Finally, the reliability of a novel strain model was also investigated and compared to the other considered relationships.

Abstract

In this paper, a study on the ultimate axial strain of the fiber-reinforced polymer (FRP) confined concrete is presented. To this aim, a large database was assembled from the scientific literature including results from compression tests performed on over 450 FRP-confined concrete cylinders. The experimental data were then used to calibrate, through simply best-fit procedures, some of the most accredited predictive strain models available in the literature; the efficiency of the found relationships was then compared with that of the formulations proposed by other authors. Finally, the reliability of a novel strain model was also investigated and compared to the other considered relationships.
