Evaluation of the Bond-to-Concrete Properties of GFRP Rebars in Marine Environments

Infrastructures, 2018
Increased traffic in combination with growing environmental impacts have led to the accelerated degradation of built infrastructure. In reinforced concrete structures, the corrosion of steel reinforcement is the predominant cause of deterioration.

Flexural Capacity and Behaviour of Geopolymer Concrete Beams Reinforced with Glass Fibre-Reinforced Polymer Bars

International Journal of Concrete Structures and Materials, 2020
Geopolymer concrete (GPC) with Glass fibre-reinforced polymer (GFRP) bars can provide a better construction system with high sustainability, high durability, and adequate strength. Few studies deal with the combination of these materials.

Experimental cyclic behavior of concrete interfaces with postinstalled reinforcing bars or alternative connectors

Structural Concrete, Volume 24, Issue 4, Page 5265-5283, August 2023., 2023
Abstract In this experimental campaign, concrete‐to‐concrete interfaces were examined under cyclic actions, crossed by postinstalled reinforcing bars or industrial steel screws. In addition, the effect of the embedment length and the roughness was investigated.

Theoretical and experimental investigation of the time‐dependent relaxation rates of GFRP and BFRP reinforcement bars

Structural Concrete, Volume 24, Issue 2, Page 2800-2816, April 2023., 2023
Abstract Cracked concrete members with fiber‐reinforced polymer (FRP) reinforcement generally suffer from increased deflections compared to steel‐reinforced members due to FRP reinforcements' lower modulus of elasticity. An approach to counteract this problem can be the prestressing of the FRP reinforcement, which can significantly reduce member ...

Assessing the Influence of Local Rebar Strain Demand on the Cyclic Behavior and Repairability of Concrete Beams Reinforced with Steel and GFRP Rebars [PDF]

Journal of Rehabilitation in Civil Engineering
Yielding of longitudinal rebars in reinforced concrete (RC) elements leads to the localization of damage and consequently increases repair costs. Two options are available to mitigate this localization in rebar strain: the use of debonded-steel rebars or

Deflection behaviour of FRP reinforced concrete beams and slabs: An experimental investigation [PDF]

, 2012
The flexural response of FRP RC elements is investigated through load–deflection tests on 24 RC beams and slabs with glass FRP (GFRP) and carbon FRP (CFRP) reinforcement covering a wide range of reinforcement ratios.

Replacement of steel rebars by GFRP rebars in the concrete structures

Karbala International Journal of Modern Science, 2018
Abstract Glass fiber reinforced polymer (GFRP) has been confirmed to be the solution as a major development in strengthened concrete technology. Synthesis of GFRP rebars by using the longitudinal glass fibers (reinforcement material) and unsaturated polyester resin with 1% MEKP (matrix material) via manual process.

Fibres for enhancing of the bond capacity between GFRP rebar and concrete [PDF]

, 2014
The effect of steel fibres (SF) and macro-polypropylene fibres (PPA) on the bond capacity between GFRP rebar and concrete has been studied in this work. A novel method using the equivalent bond strength to evaluate the bond toughness is proposed.
