Damping Analysis of GFRP Bars

2015
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

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.

Fire Endurance of Concrete Elements Reinforced with GFRP Bars

Advanced Materials Research, 2013
Fire 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.

GFRP Bar Reinforced Concrete Bridge Deck: Stress in GFRP Bar under Ultimate Design Loads

Advanced Materials Research, 2011
In 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.

A model for the bond-slip of a GFRP bar in concrete

Engineering Structures, 2017
Abstract Glass fiber reinforced polymer (GFRP) bars are emerging as desirable alternatives for traditional steel reinforcements in concrete industry. A proper bond between concrete and reinforcement is critical for the performance of reinforced concrete structures.

Durability of GFRP Reinforcement Bars

2011
Results 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,

Prediction of the creep rupture strength of GFRP bars

Construction and Building Materials, 2019
Abstract The experimental portion of this study presents the results of an investigation into the unconditioned creep rupture strength of two different types of 12.7 mm GFRP bar both made with vinylester resin and ECR glass fibers but with different surface enhancements.

Performace of Muiti-bar GFRP Tiebacks

Deep Foundations Institute 50th Annual Conference Proceedings
Multi-bar tiebacks by MST, made from Glass Fiber Reinforced Polymer (GFRP), offer an innovative solution for both temporary and long-term anchoring applications, providing numerous advantages over traditional steel tiebacks. A key feature of multi-bar GFRP tiebacks by MST is their low relaxation, improved creep behavior, and very high bond strength ...

Durability of GFRP bars: a critical review of the literature

Progress in Structural Engineering and Materials, 2005
AbstractThe research undertaken during the last two decades has shown that one of the potential solutions to the steel‐corrosion‐related problems in concrete is the use of fiber‐reinforced composite (FRP) reinforcement as a replacement for traditional steel bars.
