Bond coefficient, kb, of GFRP bars
Construction and Building Materials, 2021Abstract Due to the increase in the number of manufacturers of GFRP bars, there is currently a variety of products in the marketplace with different physical and mechanical properties. These differences directly influence the bond coefficient, kb, a coefficient intended to relate the behavior of GFRP to that of steel bars for the computation of crack

Durability of GFRP Bars with Different Bar Diameters
IABSE Reports, 2019<p>This study investigates a test concept to derive a reliable long-term strength estimation of GFRP bars in concrete environment. Using the time to failure method, test results of straight GFRP bars with different diameters were compared. To represent closely the in service-conditions of concrete structures, the examined bars were subjected to a

Response of GFRP bars at different temperatures
Materials Research Proceedings, 2023Abstract. Owing to their numerous advantages, industries have been adopting fiber-reinforced polymer (FRP) bars as reinforcement in concrete members due to their superior mechanical properties and high durability. More specifically, glass FRP (GFRP) bars have been increasingly adopted for use in harsh environmental conditions due to their excellent ...

Innovative Design of GFRP Bars for Concrete Structures
Advanced Materials Research, 2012This part analyzed GFRP rebar’s research situation, summarized its behaviuor as internal reinforcement for concrete structures. The research has been developed over recent years, however the rules and standard codes for design RC concrete structures with these rebars not consider that the internal reinforcement can work in compression.

Durability of GFRP reinforcing bars in seawater concrete
Construction and Building Materials, 2021Abstract This paper presents an experimental study that investigated the durability performance of unstressed glass fiber-reinforced polymer (GFRP) bars embedded in concrete mixed with seawater (seawater concrete). GFRP bars were extracted from concrete elements made with two different seawater concrete mix designs and exposed to different ...

Flexural Behaviour of Concrete Beams Reinforced With GFRP Bars
Strain, 2010Abstract: The paper presents some of the results from a large experimental program undertaken at the Department of Civil Engineering of Salerno University. The static behaviour under service conditions of concrete beams reinforced with GFRP (Glass Fibre‐Reinforced Polymer) as well as CFRP (Carbon Fibre‐Reinforced Polymer) bars and stirrups is examined.

The main objective of this work is to contribute to a better understanding of the dynamic behavior of composite bars. In this work we propose an experimental modal analysis of Glass Fibers Reinforced Polymers (GFRP) bars. The objective is to characterize the damping properties of this material through vibration tests. It was found that these properties

Fire Endurance of Concrete Elements Reinforced with GFRP Bars
Advanced Materials Research, 2013Fire engineering is primarily to prevent loss of life or injury during a fire. Obviously the best way to achieve this is to prevent ignition, minimizing fire spread and smoke, dying the fire before it has fully developed. When this is not possible, when the fire is fully developed, structural elements must guarantee sufficient fire resistance.

Durability of GFRP Reinforcement Bars
2011Results of a 3-year-long investigation of durability of one type of glass fiber reinforced vinylester composite reinforcement bar are summarized. Bars were cast in concrete beams and subjected to simultaneous sustained load and exposure to one of four different environments: ambient indoor laboratory, natural outdoor weathering in central Pennsylvania,
