Abstract

The concept of prestressing has been used as an effective technique to strengthen composite steelconcrete girders in bridges and buildings. Although several researchers have investigated the behavior of this structural system under static loading, no one has addressed the fatigue behavior. This paper analyzes and summarizes the fatigue test data for the main constituent components of prestressed composite steel-concrete girders—strands, shear studs, and cover plates. The data are also compared with the American Association of State Highway and Transportation Officials (AASHTO) requirements. It appears that end-anchored strands for nonbonded, prestressed structures can be designed for fatigue to the AASHTO allowable stress range for category C. AASHTO’s approach to designing shear studs and cover plates seems reasonable for prestressed composite girders. A companion paper presents the fatigue behavior of these elements within a prestressed composite girder.
