The lack of a comprehensive, validated, and easily accessible data base for the durability of fiber-reinforced polymer _FRP_composites as related to civil infrastructure applications has been identified as a critical barrier to widespread acceptance of these materialsby structural designers and civil engineers. This concern is emphasized since the structures of interest are primarily load bearing and areexpected to remain in service over extended periods of time without significant inspection or maintenance. This paper presents a synopsisof a gap analysis study undertaken under the aegis of the Civil Engineering Research Foundation and the Federal Highway Administrationto identify and prioritize critical gaps in durability data. The study focuses on the use of FRP in internal reinforcement, externalstrengthening, seismic retrofit, bridge decks, structural profiles, and panels. Environments of interest are moisture/solution, alkalinity,creep/relaxation, fatigue, fire, thermal effects including freeze-thaw, and ultraviolet exposure.
