Guidelines for the Design of Prestressed Concrete Bridge Girders Using FRP Auxiliary Reinforcement

The state departments of transportation (DOTs) have been investigating alternative reinforcement materials such as fiber reinforced polymers (FRP) to extend the service life of highway structures especially in aggressively corrosive environments. In the effort to further facilitate the use of these materials, the American Association of State Highway and Transportation Officials (AASHTO) adopted the AASHTO Guide Specification for the Design of Concrete Bridge Beams Prestressed with Carbon Fiber-Reinforced Polymer (CFRP) Systems and the AASHTO LRFD Bridge Design Guide Specifications for GFRP-Reinforced Concrete. Herein, both are referred to as AASHTO FRP guide specifications. The current AASHTO specifications do not address the design of FRP auxiliary (non-prestressed) reinforcement in prestressed concrete girders. The behavior and the mechanical properties of FRP reinforcement (including carbon, glass, and basalt FRP reinforcement) are different from the traditional steel reinforcement, which is the basis of the current design specifications. Bridge owners, fabricators, designers, and contractors need specifications and guidelines for the design of prestressed concrete girders using FRP auxiliary reinforcement. The objectives of this research are to (1) propose modifications to the AASHTO FRP guide specifications for the design of prestressed concrete girders using FRP auxiliary (non-prestressed) reinforcement and (2) develop guidelines for the design of prestressed concrete girders using FRP auxiliary reinforcement including design examples and training materials to demonstrate the application of the proposed AASHTO FRP guide specifications modifications and guidelines.
