Experimental and design‐oriented research on fiber reinforced concrete segmental tunnel linings: A systematic review

Structural Concrete, EarlyView.
Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...

On developing accurate prediction models for residual tensile strength of GFRP bars under alkaline-concrete environment using a combined ensemble machine learning methods

Case Studies in Construction Materials, 2023
GFRP (Glass-fiber reinforced polymer) bars are recognized as a structural material enabling replace existing steel rebar. However, GFRP bars exhibit a decrease in tensile strength under severe conditions such as strong alkalinity, high salinity, and ...

The challenges of GFRP RC beam design for limit states

Structural Concrete, EarlyView.
Abstract Glass fiber reinforced polymer (GFRP) bars are used ever more frequently in concrete construction due to their non‐corrosive and anti‐magnetic properties. Their research over the past decades focused on fundamental questions, such as the design aspects of beams under flexural loads.

Long-term behavior of GFRP reinforcing bars

Composite Structures, 2019
Abstract Glass fiber reinforced polymer (GFRP) bars represent a valid solution as internal reinforcement of concrete members for some particular applications. GFRP reinforcing bars (rebars) have a high-strength-to-weight ratio and good resistance to corrosion.

Structural Behavior of Reinforced Concrete Columns Fully and Partially Reinforced with GFRP Bars Tested Under Concentric or Eccentric Compressive Loads

Diyala Journal of Engineering Sciences
Concrete columns reinforced with glass fiber-reinforced polymer (GFRP) bars have been greatly interesting recently. The distinct properties of GFRP bars, such as high tensile strength and low modulus of elasticity compared to steel bars, as well as the ...

Experimental and numerical investigation on the flexural response of GFRP‐reinforced SFRC beams

Structural Concrete, EarlyView.
Abstract In order to address the challenges related to the deformability and ductility of concrete beams reinforced with fiber reinforced polymer (FRP) bars, an alternative solution involving steel fiber reinforced concrete (SFRC) has been proposed. In the present study, a total of seven beams—including one steel‐reinforced reference beam and six glass

THE FATIGUE BEHAVIOUR OF GFRP BARS - EXPERIMENTAL STUDY

Acta Polytechnica CTU Proceedings, 2019
The paper describes an experimental program for studying the fatigue performance of GFRP bars, which has been initiated by the authors. Two different test configurations were used to assess the fatigue behaviour. The bare specimens were tested within the first series.

Novel Recyclable Hierarchical Carbon Fiber/Epoxy Composites: Preserving Fiber Length and Orientation Using Elium

Polymer Composites, Volume 47, Issue 11, Page 9939-9954, 10 June 2026.
Schematic illustration of a hierarchical recycling approach that preserves reinforcing fiber orientation. ABSTRACT Current recycling methods for polymer matrix composites produce short, unoriented carbon fibers, limiting their use to intermediate‐strength applications.
