This paper reports on the North American state-of-the-art in the use of FRP composites in concrete structures. for new construction, FRP bars have been used as the internal reinforcement in concrete members to replace conventional steel rebars for a host of reasons. the principles for design and construction have been established and proposed to industry by the American Concrete Institute (ACI). for repair and upgrade, strengthening of concrete members with externally bonded FRP laminates or near surface mounted (NSM) bars has received remarkable attention. the design and construction principles for use in practice are being finalized by ACI. on the application side, FRP materials have been used in some multi-million-dollar projects for strengthening parking garages, multi-purpose convention centers, office buildings and silos. the drivers for this technology are several, but perhaps the most relevant one is the ease of installation. in the repair/upgrade arena (as well as new construction), perhaps one of the most important unresolved questions remains that of durability (including fire resistance). Further research and validation are necessary to increase confidence in FRP technology for concrete construction. © 2003 Elsevier Ltd. All rights reserved.
