This proceedings is a collection of 29 papers presented at the specialty workshop, Composites in Construction: A Reality, held at Villa Orlandi, the International Center for Scientific Culture of Naples University ""Frederico II,"" Capri, Italy. These papers address the state-of-the-art in fiber-reinforced polymer (FRP) composites for use in construction. FRP composites are expected to significantly improve the performance and durability of new or deteriorated constructed facilities. FRP composites can be used as stand-alone structural members, as reinforcement for prestressed and non-prestressed concrete, or in combination with other structural materials for new construction or repair/rehabilitation. The increased interest in FRP composites is fueled by innovative manufacturing technologies as well as significantly more stable, stronger constituent materials. Topics covered include: codes and standards; manufacturing, economics, and construction; materials, durability, and characterization; analysis and design; and outcomes.
