This study was numerically focused on the non-linear behaviour of glass fibre reinforced polymer (GFRP) concrete beams with different amounts transverse reinforcement. The mid-span deflection beam cannot effectively be restricted using higher amount flexural GFRP bars, owing to their low deformability factor. So, use high reinforcement ratio is proposed decrease and crack widths. Following this...

Fiber-Reinforced Polymer (FRP) bars/strands are the most promising alternative to their steel counterparts for reinforcing concrete elements due resistance corrosion, lighter weight, higher strength and better durability. However, very limited research has been conducted in relation non-destructive testing (NDT) methods that applicable damage detection FRP bars or of reinforcements embedded con...

The present study aims to evaluate the performance of concrete beams with different Fiber Reinforced Polymer (FRP) and steel bars exposed elevated temperatures through a detailed experimental investigation. Flexural behavior is analyzed Carbon (CFRP), Basalt (BFRP), Glass (GFRP), tests. Beams were temperature 925 °C (1 hr) following standard fire curve, subsequently cooled by either natural or ...

In this paper, it is proposed to study the static flexural performance of hybrid (glass and steel) fiber reinforced M30 grade self-compacting concrete (SCC) beams made with glass reinforcement polymer (GFRP) re-bars. Nan Su mix design approach adopted develop plain SCC (PSCC) mixes. Glass fibre (GFRSCC), steel (GFRSCC) (HFRSCC) mixes are prepared using optimum dosages (0.05%) fibres (1%) by vol...

RATIONALE GTP cyclohydrolase I (GTPCH-1) is the rate-limiting enzyme involved in de novo biosynthesis of tetrahydrobiopterin (BH(4)), an essential cofactor for NO synthases and aromatic amino acid hydroxylases. GTPCH-1 undergoes negative feedback regulation by its end-product BH(4) via interaction with the GTP cyclohydrolase feedback regulatory protein (GFRP). Such a negative feedback mechanism...

This study investigates the performance of monolithic and newly proposed dry beam-column joints using GFRP bolts, reinforcements, different types fibres subjected to pendulum impact. Six specimens were cast tested with increasing impact velocity until failure. The experimental results have shown that concrete joint reinforced bars showed better behaviour in terms energy dissipation (up 51%), re...
