Abstract:This paper provides an overview of the ACI 440.4R-04 document on“Prestressing Concrete with FRP Tendons” reported by ACI Committee 440 on “Fiber-Reinforced Polymer Reinforcements”. The document is one of the Emerging TechnologySeries published by ACI. The paper outlines the content of the document and thephilosophy of applying FRP technology as opposed to conventional steel forprestressing. The document offers general information on the history and use of FRP forprestressing applications, and a description of the unique material properties of FRP. Italso focuses on the current state of design, development, and research needed tocharacterize and ensure the performance of FRP as prestressing tendons in concretestructures. The proposed guidelines are based on knowledge gained from worldwideexperimental research, analytical work, and field applications of FRPs used asprestressed tendon. Current developments in the document include a basicunderstanding of flexural and axial prestressed members with FRP tendons, FRP shearreinforcement, bond of FRP tendons, and unbonded or external FRP tendons forprestressing applications. The document concludes with a list of research needs.
