This article examines the use of fibre reinforced polymer (FRP) composites as a method of strengthening concrete structures. FRP composites often enable such structures to be repaired and retained, in situations where they would otherwise have to be demolished. FRP composites have been used extensively for flexural strengthening of bridge decks and abutments, and occasionally to increase shear capacity. Modern FRP composites comprise a matrix of fibres and resin. The fibres used for structural purposes are made of glass, aramid, or carbon, and the resins are usually epoxies or vinyl esters. Glass fibres are relatively inexpensive, and many composites use them in conjunction with polyester resins. However, carbon fibres have given the construction industry its desired combination of strength, stiffness, and durability; they can sometimes be up to ten times as strong as mild steel, while possessing comparable stiffness. Two case studies of the use of FRP composites are described: (1) the modification of the Pioneer Centre, a reinforced concrete structure built in 1932 in Nunhead, London, which used to be a health centre and is being converted into flats; and (2) Sycamore Lane Footbridge, Warrington, England. The article finally briefly describes research, design guidance, and future developments.
