Since the late 1980s, the civil engineering community has become interested
in the application of Fiber Reinforced Polymers (FRP) to the construction industry.
These materials are comprised of very strong fibers and a resin matrix. The most
popular application of FRPs has been in repair and rehabilitation of structures. In
this technique, FRPs are bonded to the exterior surface of the structural element
and will act as supplementary steel reinforcement for flexure, shear or
confinement enhancement. High tensile strength, flexibility and lightweight of
FRPs are among their salient advantages. This paper discusses some of the
pioneering research conducted by the author and his associates and provides
examples of field applications where FRPs have been successfully used.
