Most of the standing structures today have already deteriorated or are on verge deterioration due to an increase in their age and harsh environmental conditions. For this very reason, need being upgraded replaced. Retrofitting using near-surface mounted (NSM) fiber-reinforced polymer (FRP) rods has now emerged as a promising technique for strengthening reinforced concrete members by increasing ...

Over the last two decades fiber-reinforced polymer (FRP) rods have emerged as one of the most promising and affordable solutions to the corrosion problems of steel reinforcement in structural concrete. The application of FRP rods in new or damaged structures requires the development of design equations that must take into account the mechanical properties and the durability properties of FRP pr...

Fiber reinforced polymer (FRP) material is currently being produced in different configurations and widely used to strengthen and retrofit concrete structures and bridges. It is also possible to apply other strengthening methods without changing the appearance or the dimensions of the structure. Near Surface Mounted (NSM) is a recent strengthening method using CFRP bars (rods or laminate strips...

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...

Abstract In reinforced concrete (RC) structures, corbels that extend from the faces of columns are commonly employed to support primary beams and girders. Frequently, use is limited cantilevers with a shear span-depth ratio often less than 2. Because this relatively low ratio, corbel strength normally dominated by shear, which comparable deep beams. However, owing some reasons (e.g., design and...

This paper discusses the Finite Element analysis (FE) conducted to predict behavior of Glass Fiber Reinforced Concrete (GFRC) beams without shear reinforcement (stirrups) and strengthen them with proposed techniques increase their strength. for this study, A total eighteen (18) (120 * 300 2200 mm) specimens were modeled using Ansys™ mechanical. The main variables percentage discrete glass fiber...

Unreinforced masonry (URM) walls are prone to failure when subjected to out-of-plane loads caused by earthquakes or high wind pressures. In this context, fiber reinforced polymer (FRP) materials may be a solution to solve or lessen the effects of this overloading. This paper describes an experimental program dealing with the flexural behavior of nine concrete URM walls strengthened with glass F...

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...

Glass fiber reinforced polymer (GFRP) composites are widely used in infrastructure applications including water structures due to their relatively high durability, high strength to weight ratio, and non-corrosiveness. Here we demonstrate the potential use of carbon nanoparticles dispersed during GFRP composite fabrication to reduce water absorption of GFRP and to enable monitoring of moisture d...
