Development of FRP Bridge Superstructural Systems
Corrosion related damages of highway bridges have led federal and state agencies to investigate the application of new and unconventional materials such as fiber reinforced plastic (FRP) structural shaped for bridges. Therefore, the major objective of the research is to assemble, test and evaluate FRP shapes as bridge superstructural components. Before coupon testing and those results were theoretically validated. In addition, two test specimens were assembled and tested under concentric, eccentric, and uniform line loads and structural efficiency of each specimen is monitored. The research results are analyzed in terms of joint efficiency, transverse load distribution, torsional efficiency, and composite action between deck and stringers. An orthotropic plate theory was adopted to predict the behavior of each test speciman, and the solutions were based on the first term approximation of Fourier analysis. Shear deflections were introduced in the analysis due to the nature of the material. Simplified methods were used to establish the effective stiffness of each FRP component.
