The double strap joint splicing of glass fiber reinforced polymer (GFRP) bars for concrete (RC) beams strengthening, applying the near surface mounting (NSM) method, has been proposed in paper. method consists application supplementary GFRP symmetrically positioned cut-off zone main reinforcement. performances this have experimentally tested most unfavorable case reinforcement maximal bending m...

A multilaboratory investigation into the durability of glass fiber–reinforced polymer (GFRP) bars extracted from eleven 15- to 20-year-old bridges in US will be performed. Part 1 (Benzecry et al., forthcoming) this two-paper series describes and presents data on condition their concrete, 2 focuses bars. Constituent content, maximum water absorption, as-received moisture transition temperature (...

Concrete structures provided with steel bars may undergo deterioration due to fatigue and corrosion, which leads an increase in repair maintenance costs. An innovative approach eliminating these drawbacks lies the utilisation of glass-fibre-reinforced polymer (GFRP) sheets as reinforcement concrete instead bars. This article relates investigation flexural behaviour ordinary portland cement (OPC...

GTP cyclohydrolase I feedback regulatory protein (GFRP) mediates feedback inhibition of GTP cyclohydrolase I activity by tetrahydrobiopterin and also mediates the stimulatory effect of phenylalanine on the enzyme activity. To characterize the molecular structure of GFRP, we have purified it from rat liver using an efficient step of affinity chromatography and isolated cDNA clones, based on part...

Abstract Since the nineteenth century, reinforced concrete was evolved as a crucial material for construction. This popular composite is broadly used in different building typologies. However, decaying of steel rebar due to corrosion identified hindrance that can affect quality structures. In reference this, glass fiber-reinforced polymer (GFRP) bar essential because corrosion-resistant propert...

Abstract This paper presents the results of an experimental study on employing near surface mounted (NSM) fiber-reinforced polymer (FRP) reinforcement technique, and L?shape ribbed bars, for flexural strengthening lightweight reinforced concrete (RC) beams. 18 RC beams including 14 four normal-weight were designed. The strengthened with glass (GFRP) bars carbon (CFRP) laminate in bending tests....
