ABSTRACT
The design requirements for the use of fiber reinforced plastics (FRP) in civil structures are significantly different from those in aerospace structures. Therefore, this study identifies and addresses the fatigue performance as well as design issues with an emphasis on strength and serviceability limit states. Design methodology for concrete decks with FRP rebars is presented using experimental results. In addition to following the AASHTO specifications with some modifications, the results are applied in the design of first concrete deck with steel stringer bridge reinforced with FRP bars at McKinleyville, West Virginia, USA. The bridge will be constructed in fall 1995. Keywords: FRP composites, rebar, concrete, bridge decks, design, fatigue.
