Strength Degradation of Gfrp Bars
… degradation of Glass Fiber Reinforced Polymer (GFRP) bars at high temperature and alkalinity and determine if an Arrhenius type relationship can be used as a means of projecting life. The work done includes a thorough literature review, experiments and development of strength prediction models. …

Behaviour of continuous concrete deep beams reinforced with GFRP bars
… the behaviour of glass fibre reinforced polymer bars (GFRP) reinforced continuous concrete deep beams. For this purpose, experimental, analytical and numerical studies were conducted. Nine continuous concrete deep beams reinforced with GFRP bars and one specimen reinforced with steel bars were …

Reliability-based durability assessment of GFRP bars for reinforced concrete
… durability of glass fiber reinforced polymer (GFRP) reinforced concrete designed for flexure. The results of this simulation can be used to determine appropriate flexural strength reduction factors. Prior to conducting the simulation, long-term GFRP tensile strength values needed to be …

Bending behavior of concrete T-beams reinforced with glass fiber-reinforced polymer (GFRP) bars
Concrete slabs are integrally cast with girders or stringers (stiffening system) resulting in floor slabs, bridge decks, footers, retaining structures and others. A portion of slab between a stiffening system acts as flange and bends in unison with the stiffening system, i.e., classic T-beam …

Behavior of RC hollow circular columns reinforced with GFRP bars and spirals under concentric and eccentric loads
L’un des problèmes les plus graves auxquels sont confrontées les structures en béton armé d’acier est la détérioration des éléments structuraux causée par l’aggravation des problèmes de corrosion de l’acier, en particulier dans les environnements difficiles tels que les structures marines, les …

Performance of a Bridge Deck with Glass Fiber Reinforced Polymer (GFRP) Bars as the Top Mat of Reinforcement
… investigate the effectiveness and durability of GFRP bars as reinforcement for concrete decks. Today's rapid bridge deck deterioration is calling for a replacement for steel reinforcement. The advantages of GFRP such as its high tensile strength, light weight, and resistance to corrosion make it …

Bond Strength and Development Length of Sand-Coated GFRP Bars Spaced and Bundled in Normal Strength and Ultra-High-Performance Fibre-Reinforced Concrete
… sand- coated glass fibre-reinforced polymer (GFRP) bar sizes (#4, 5 and 8) embedded into ultra-high- performance fibre-reinforced concrete (UHPFRC) with 2% steel fibres. It also examines the Ld of sand-coated #5 GFRP bars bundled in two and three embedded into normal strength concrete (NSC). …

Laboratory Tests of a Bridge Deck Prototype With Glass Fiber Reinforced Polymer Bars as the Top Mat of Reinforcement
… prototype of an actual bridge deck containing GFRP bars as the top mat of reinforcement. The purpose of the tests was to verify that the design would resist the loads for which it was designed and provide assurance that the deck would not unexpectedly fail due to the use of this new material. …

Field Test of a Bridge Deck with Glass Fiber Reinforced Polymer Bars as the Top Mat of Reinforcement
… to perform live load tests on a bridge deck with GFRP reinforcement in the field under service conditions. The strains and deflections in the span reinforced with GFRP in the top mat were recorded under a series of truck crossings, and these were compared to the span reinforced with all steel bars …

Bond of glass fibre reinforced polymer bars in high strength concrete
… examine bond of glass fibre reinforced polymer (GFRP) bars with high concrete strength. The current research project aims to compare between bond measured from a pull-out test and a hinged beam test for GFRP bars embedded in high strength concrete. Different parameters influencing bond such as …

Durability behavior of fiber reinforced polymer and steel reinforced polymer for infrastructure applications
… concrete which will then corrode steel bars as RC structures are exposed to harsh weather. In the last decade, composite reinforcement systems are internally or externally applied to concrete structures instead of traditional steel reinforcing bars, or to strengthen concrete elements in …

Development of high-performance fiber-reinforced link slabs for jointless bridge decks
… reinforced with glass fiber reinforced polymer (GFRP) bars was to investigate its use as link slabs to replace the expansion joints commonly found in bridge decks. Numerous small scale test specimens and a full scale specimen test were conducted. The small scale test specimens consisted of 3 inch …

Flexural Behaviour of Geopolymer Concrete T-beams Reinforced with FRP or Hybrid FRP/Steel bars
… for concern for the construction industry. FRP bars are replaced for steel reinforcing bars in severe environments to prevent corrosion. Each tonne of OPCC produces an extra tonne of CO2. The OPCC must be replaced with binders that emit less CO2. Geopolymer binder is an alternative to Portland …

Flexural behaviour of continuously supported FRP reinforced concrete beams.
… has investigated the application of CFRP and GFRP bars as longitudinal reinforcement for continuously supported concrete beams. Two series of simply and continuously supported CFRP and GFRP reinforced concrete beams were tested in flexure. In addition, a continuously supported steel reinforced …

Behaviour of continuous concrete T-beams reinforced with hybrid FRP/Steel bars
… reinforced with glass fibre reinforced polymer (GFRP) bars while the other five beams were reinforced with a different combination of GFRP and steel bars. The ratio of GFRP to steel reinforcement at both mid-span and middle-support sections was the main parameter investigated. The results showed …
