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.

Stiffness-based design-oriented compressive stress-strain model for large-rupture-strain (LRS) FRP-confined concrete
TL;DR: 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.

Experimental study on influence of proposed FRP-strengthening techniques on RC circular short columns considering different types of damage index
TL;DR: In this paper, three new methods for strengthening RC circular short columns, including the Near Surface Mounted (NSM), externally bonded with new pattern and an innovative hybrid strengthening technique (using near-surface mounted method in the form of spiral grooves filled with CFRP hand-made bar in composition with externally bonded CFRP sheet) and compare them with two common methods of strengthening.
