Many studies on fiber reinforced polymer composite bars, as a substitute for reinforcing bars, have been conducted to solve corrosion of steel in reinforced concrete structures since 1960s’. However, FRP Bars have a lower elastic modulus than steel rebar as a structural component of concrete structures. Material properties with brittleness fracture and low elastic modulus can be improved by com...

Reinforced concrete (RC) structures require strengthening for numerous factors, such as increased load, modification of the structural systems, structural upgrade or errors in the design and construction stages. The side near-surface mounted (SNSM) strengthening technique with glass fiber-reinforced polymer (GFRP) bars is a relatively new emerging technique for enhancing the flexural capacities...

Abstract The preliminary findings of cyclic tests conducted on a series half-scale unstrengthened and strengthened masonry walls are presented. Reinforced were by (i) non-prestressed near surface mounted (NSM) glass fibre reinforced polymer (GFRP) bars (ii) prestressed NSM GFRP. Walls symmetrically vertical passing through both mortar bricks. structure was subjected to concurrent sustained unif...

In this paper, a comprehensive experimental study was conducted to investigate the bond performance of sand-coated glass fiber reinforced polymer (GFRP) bars embedded in normal concrete with different bar sizes and regions beams following regulation Rilem beam. The achieved results are compared analytical equations presented by current codes reputable recent research using average strength free...

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...
