TLDR
In this paper, a design-oriented model was developed to define axial stiffness using the jacket stiffness rather than its rupture strain, which is applicable to both conventional and large rupture strain fiber-reinforced polymers (LRS FRP)-confined concrete columns.About:

Axial compressive behavior of polyethylene terephthalate/carbon FRP-confined seawater sea-sand concrete in circular columns
Jun-Jie Zeng,Jun-Jie Zeng,Wan-Yang Gao,Wan-Yang Gao,Zhi-Jian Duan,Yu-Lei Bai,Yong-Chang Guo,Li-Jun Ouyang +7 more
TL;DR: In this paper, the authors present results from the first-ever experimental study on the behavior of axially loaded circular sea-sand concrete columns confined by polyethylene terephthalate (PET) FRP jackets, which are composed of a new and more promising type of FRP composites with a bilinear stress-strain response and a large rupture strain.

Compressive Behavior of Concrete Confined by Carbon Fiber Composite Jackets
TL;DR: In this paper, axial compression test results of 27 concrete cylinders confined by carbon fiber reinforced polymer composite jackets were described, and the failure of the confined concrete was dominated by the rupture of the jacket at an average strain much smaller than the ultimate strain obtained from tension tests of flat coupons.
