Three-Dimensional Finite-Element Analysis of FRP-Confined Circular Concrete Columns under Eccentric Loading
Guan Lin,Jinguang Teng +1 more
TL;DR: Fiber-reinforced polymer (FRP) jacketing/wrapping has become a widely accepted technique for strengthening/retrofitting reinforced concrete (RC) columns as mentioned in this paper.

Advanced stress-strain model for FRP-confined concrete in square columns
Guan Lin,Jinguang Teng +1 more
TL;DR: In this article, the authors present a new attempt at understanding and modeling the confinement mechanism in square columns as a special case of rectangular columns, leading to a new stress-strain model.

Compressive behaviour of stub concrete column strengthened with ultra-high performance concrete jacket
Jian Xie,Quanhong Fu,Jia-Bao Yan +2 more
TL;DR: In this article, the authors performed compressive tests on 18 stub concrete columns with externally confined ultra-high performance concrete (UHPC) jacket and found that increasing the thickness of confining UHPC jacket significantly improved the compressive behaviours of concrete stub columns for cylindrical shaped column.
Journal ArticleDOI
Behavior and Three-Dimensional Finite Element Modeling of Circular Concrete Columns Partially Wrapped with FRP Strips.
TL;DR: A reliable three-dimensional (3D) finite element (FE) approach for modeling of partially FRP-confined circular columns was established and an accurate plastic-damage model for concrete under multiaxial compression is employed.

Triaxial test for concrete under non-uniform passive confinement
Mohsen Mohammadi,Yu-Fei Wu +1 more
TL;DR: In this paper, a triaxial test for monotonic and cyclic compression tests of concrete cubes is presented. But the triaxials are not suitable for passively confined concrete cubes, such as fiber reinforced polymer (FRP) confined concrete.

Nonlocal damage theory
TL;DR: In this paper, the authors proposed a nonlocal damage theory, which is based on the nonlocal treatment of damage from the local treatment of elastic behavior, and the only required modification is to replace the usual local damage energy release rate with its spatial average over the representative volume of the material whose size is a characteristic of a material.

FRP: Strengthened RC Structures

A description of micro- and macroscale damage of concrete structures
TL;DR: In this paper, an isotropic elastic damage model is proposed by using the coupling of two damage variables, D t (tensile effects) and D c (compressive effects).

Behavior of Concrete Columns Confined by Fiber Composites
Amir Mirmiran,Mohsen Shahawy +1 more
TL;DR: In this paper, a series of uniaxial compression tests on concrete-filled fiber reinforced plastic (FRP) tubes are compared with the available confinement models in the literature.
Journal ArticleDOI
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.
