Numerical Investigation and Cost Analysis of FRP-Concrete Unidirectional Hybrid Slabs

International Journal of Applied Mechanics and Engineering, 2021
Fiber-reinforced polymer (FRP) has been commonly used to reinforce concrete structures. The kinds of FRP demonstrate an effective alternative to various methods of reinforcement in concrete structures subjected to bad environmental conditions which cause

Effect of Ammonium Polyphosphate/Silicate Content on the Postfire Mechanics of Epoxy Glass‐Fiber Composites Using Facile Chocolate Bar‐Inspired Structures

Fire and Materials, Volume 49, Issue 3, Page 329-346, April 2025.
ABSTRACT This study investigates the postfire mechanical properties of epoxy glass‐fiber reinforced composites (EP GFRCs) using increasing concentrations of ammonium polyphosphate (APP) and inorganic silicate (InSi) to modify the char and fire residue.

Flexural response of GFRP RC beams strengthened with side and bottom NSM GFRP bars

Case Studies in Construction Materials, 2023
Este estudio muestra el rendimiento de flexión de las vigas de hormigón armado (RC) con varillas de polímero reforzado con fibra de vidrio (GFRP). Las vigas se reforzaron con los métodos de montaje en superficie cerca de la parte inferior o lateral (BNSM o SNSM). Aplicar el fortalecimiento de BNSM a la viga RC es difícil en algunos casos, por lo que el

Mechanical Behaviour of Vacuum‐Infused GFRP Composites at Elevated Temperatures—Influence of Fibre Architecture

Fire and Materials, EarlyView.
ABSTRACT This study addresses the influence of fibre architecture on the mechanical properties of vacuum‐infused glass fibre reinforced polymer (GFRP) composites at elevated temperatures (ET). Laminates with three different fibre configurations—unidirectional (UD), bidirectional 0°/90° cross‐ply (BD), and ±45° off‐axis angle‐ply (OA) – were tested in ...

Multi-Leg Shear Reinforcement of Gfrp and Steel Lwrc Edge Column-Slab Connections: A Comparison Study

Communications
The behaviour of lightweight concrete (LWC) edge column-slab connections reinforced with two types of flexural reinforcement glass fiber-reinforced polymer (GFRP) and steel bars with different ratios of shear reinforcement are investigated experimentally

Durability Prediction of GFRP Rebar Based on Elastic Modulus Degradation

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.

Post - cracking behavior of the tensile specimens made from Ultra high performance concrete, reinforced by GFRP rebar [PDF]

Journal of Structural and Construction Engineering, 2019
Since it is very important to know the material's behavior to evaluate the nonlinear behavior of structures, it is necessary to know the tension stiffening phenomenon and its effect on the behavior of the reinforced concrete members to examine their ...

Characteristics on Trimming of GFRP.

Journal of the Japan Society for Precision Engineering, 1991
GFRP, because of their superior strength-to-weight and stiffness-to-weight ratio, are used increasingly in high-performance applications. But the users of this material have faced a difficulty to machine them. The major trouble in cutting GFRP is the decreased tool-life, the inferior surface quality and others.

Hybrid Steel/NSM/GFRP System Versus GFRP Wrapping for Upgrading RC Wall-like Columns

Polymers, 2023
Reinforced concrete (RC) wall-like columns are commonly employed in structures in Saudi Arabia. These columns are preferred by architects owing to their minimum projection in the usable space. However, they often need strengthening due to several reasons, such as the addition of more stories and increasing the live load as a result of changing the ...
