Durability Prediction of GFRP Rebar Based on Elastic Modulus Degradation [PDF]

Frontiers in Materials, 2019
A conventional method to study the durability of Glass Fiber Reinforced Polymer (GFRP) rebars is to carry out tensile tests on the corroded GFRP bars.

Experimental investigation for GFRP rebar couplers for reinforced concrete

Journal of King Saud University: Engineering Sciences, 2021
The use of fiber reinforced polymer (FRP) rebars is nowadays becoming popular in reinforced concrete (RC) construction due to their excellent inherent properties such as corrosion resistance, lightweight, and high strength to weight ratio.

Effect of GFRP Stirrup Confinement on the Bond Strength of GFRP-RC Beams [PDF]

International Journal of Concrete Structures and Materials
The current provisions for development length in the ACI 440.11 code disregard the confinement effect provided by stirrups on the bond strength of longitudinal bars and require splice lengths that pose implementation challenges.

Static and Flexural Fatigue Behavior of GFRP Pultruded Rebars [PDF]

Materials, 2021
This paper presents the experimental results of composite rebars based on GFRP manufactured by a pultrusion system. The bending and radial compression strength of rods was determined. The elastic modulus of GFRP rebars is significantly lower than for steel rebars, while the static flexural properties are higher.

Effect of GFRP rebars and polypropylene fibers on flexural strength in high-performance concrete beams with glass powder and microsilica

Case Studies in Construction Materials, 2023
Considering the benefits of GFRP rebars and their lighter weight compared to steel rebars and the sustainability of polypropylene fibers, GFRP rebars and polypropylene fibers are investigated as sustainable materials replacements for steel rebars in high-

Soft computing approaches towards tensile strength estimation of GFRP rebars subjected to alkaline-concrete environment

Case Studies in Construction Materials, 2022
The rising demand for coastal infrastructure has led to seawater and sea sand concrete which is highly alkaline in nature. Glass-fibre reinforced polymer (GFRP) bars are a durable alternative to conventional steel rebars; however, they are susceptible to

Seismic performance of ductile corrosion-free reinforced concrete frames

AIMS Materials Science, 2022
Corrosion of steel bars is the main cause of the deterioration of reinforced concrete (RC) structures. To avoid this problem, steel rebars can be replaced with glass-fiber-reinforced-polymer (GFRP).
