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

Failure Mode of GFRP Bar RC Beams Using GFRP Sheet as Shear Reinforcement
Materials Science Forum, 2023The objectives of this study are to analyze the pattern crack and failure mode of the GFRP concrete beam by using GFRP sheet as shear reinforcement (GFB) compared with the two types of the conventional reinforced concrete beam (CB and GB). One of the conventional reinforced concrete beams is reinforced with the steel bar (CB) and the other is the GFRP ...

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.

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 ...

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

Experimental investigations on bond performance of GFRP bars
i-manager’s Journal on Civil Engineering, 2023Corrosion of steel is one of the major problems concerning construction field which becomes more severe when the structures are subjected to harsh environment which is harmful to structure as well as costs high for repair. Hence, deviating to alternate building materials is essential in upcoming years.

GFRP Bar Reinforced Concrete Bridge Deck: Stress in GFRP Bar under Ultimate Design Loads
Advanced Materials Research, 2011In current ACI 440.1R-06 design guideline, an environmental reduction factor (ERF) is specified to account for long-term durability of GFRP bar used in reinforced concrete structures. Such ERF factor is still lack of confidence to concrete industry prior to deliberate calibrations with in-field real time data.
