FRP ‐Reinforced Concrete Structures

Abstract

This article covers the use of fiber‐reinforced polymer (FRP) as internal reinforcement in concrete structures. Mechanical and durability properties of both concrete and FRP bars are introduced; design concepts for reinforced concrete (RC) structures with internal FRP reinforcement are then presented and discussed. An overview of available test methods for the mechanical and durability characterization of both concrete and FRP bars and current guides for the design of FRP‐RC structures is provided. This article concludes with a list of examples of real field applications.

Experimental investigation of GFRP‐reinforced concrete columns made with waste aggregates under concentric and eccentric loads

“…[1][2][3][4] Many studies have been done to demonstrate the effect of using GFRP compared with steel on the axial behavior of RC columns. [5][6][7][8][9][10][11] De Luca and Nanni 12 presented a comprehensive overview of the behavior of concrete reinforced by GFRP bars. A discussion of design approaches for RC structures with internal GFRP bars follows the introduction of the mechanical and durability properties of both concrete and GFRP bars.…”

Monitoring the flexural performance of GFRP repaired corroded reinforced concrete beams using passive acoustic emission technique

“…These techniques, though delay corrosion but cannot prevent it completely. Further, the use of noncorroding fiber reinforced polymer (FRP) as an alternative reinforcement in RC structures offers a potentially good solution in place of traditional steel reinforcement especially in coastal applications 13–15 . But, these are costly and also require skilled labor for their manufacture as well as field application.…”
