Experimental and analytical investigations of the flexural behavior of hollow ±55° filament wound GFRP tubes
(Elsevier, 2021-02-01)
The behavior of ±55° filament wound glass fiber-reinforced polymer (GFRP) tubes under flexural loading was examined experimentally and analytically. A total of 15 tubes were tested under four-point bending. The main test ...
Hybrid system of longitudinal CFRP laminates and GFRP wraps for strengthening of existing circular concrete columns
(Elsevier, 2021-05-15)
This paper presents an investigation on the behavior of a strengthening system of longitudinal premanufactured carbon fiber-reinforced polymer (CFRP) laminates and transverse glass FRP (GFRP) wrapping for strengthening of ...
Self-healing of Engineering Cementitious Composite with Crystalline Admixture Under Different Exposure Conditions
(Canadian Society for Civil Engineering, 2021-05-26)
Self-healing mechanisms in concrete can promote healing of cracks with the material produced through the concrete itself. Engineered Cementitious Composites (ECC) is a special category of HighPerformance Fiber Reinforced ...
Second-order Analysis of Slender GFRP Reinforced Concrete Columns Using Artificial Neural Network
(Canadian Society for Civil Engineering, 2021-05-26)
Analysis of slender concrete columns reinforced with glass fiber-reinforced polymer (GFRP) bars is required for design and optimization purposes. Finite element, finite difference, and analytical-numerical tools were ...
Reliability-Based Evaluation of the Stiffness Reduction Factor for Slender GFRP Reinforced Concrete Columns
(Canadian Society for Civil Engineering, 2021-05-26)
The stiffness of concrete columns is adjusted by a factor referred to as the stiffness reduction factor or the stability resistance factor when utilizing the simplified second-order moment magnification method for designing ...
Tensile Properties of PET FRP with Bio-resin Polymer
(Canadian Society for Civil Engineering, 2021-05-26)
This study analyses the mechanical behaviour of polyethylene terephthalate fiber-reinforced polymer (PET FRP) made with a bio-resin polymer matrix. The utilized bio-resin is furfuryl alcohol mixed with phthaloyl dichloride ...
Analytical Investigation of Concrete Beam Reinforced with GFRP Rebars Under Low Axial Loading
(Canadian Society for Civil Engineering, 2021-05-26)
The main objective of the research presented in this paper was to perform the analytical study to investigate the flexural capacity of the concrete beam reinforced longitudinally and laterally with glass fiber-reinforced ...
Three-point Bending of Sandwich Beams with FRP Facing and PP Honeycomb Core
(Canadian Society for Civil Engineering, 2021-05-26)
In this study, two sets of sandwich beams were tested in three-point bending. The sandwich panels were fabricated in a wet layup process. The facing component was made of either polyethylene terephthalate (PET) fiber-reinforced ...
New mechanics-based confinement model and stress–strain relationship for analysis and design of concrete columns wrapped with FRP composites
(Elsevier, 2021-10-01)
The analysis and design of concrete columns wrapped with fiber-reinforced polymer (FRP) composites require the mathematical equation of stress–strain relationship and the ultimate conditions (i.e., stress and strain) ...
Slender RC Columns Strengthened with a Novel Hybrid Strengthening System of External Longitudinal and Transverse FRPs
(ASCE, 2021-10-01)
In this study, the performance of slender circular concrete columns strengthened with a novel hybrid system of longitudinally bonded prefabricated fiber-reinforced polymer (FRP) laminates and transverse FRP wrapping is ...
