This article provides an overview of a new American Concrete Institute (ACI) document that addresses the design of fiber-reinforced polymer (FRP) reinforced concrete structures. Design principles and key concepts such as flexure, shear and development length are summarized. Because this is new technology, future research is needed to provide information in areas that are still unclear, in need of additional evidence to validate performance, or are a real or perceived disadvantage. Application of FRP internal reinforcement is described for two bridge projects. Despite some unresolved issues, the ACI guide should allow the construction industry to take advantage of the potential of FRP internal reinforcement for concrete structures.
