• Abstract:
  The overarching goal of this study was to perform a comprehensive evaluation of various issues related to the strength and serviceability ; of the FRP deck panels that are available in the industry. Specific objectives were to establish critical limit states to be considered in the ; design of FRP deck panel, to provide performance specifications to designers, and to develop evaluation techniques for the deck panels in ; service. ; Two different FRP panels were studied during the research project: a sandwich panel and a pultruded panel. The sandwich panel was ; initially selected for the rehabilitation case study bridge. However, for a variety of reasons outside of the scope of this study, both the ; sandwich panel and the initial case study bridge were dropped from consideration. A new case study bridge was selected, and new ; proposals from FRP deck manufacturers were solicited. At that time, the pultruded deck was selected. Analysis and experimental results ; related to both FRP deck panels are included in this report, as information from both decks is relevant to the overarching goal of this ; study. ; In November 2009, Sugar Creek Bridge became the first bridge in Indiana to be rehabilitated with an FRP bridge deck. An extensive ; study, including literature review, analysis, and load tests, suggest that the installed deck should perform well, with web buckling as the ; ultimate failure mode at a factor of safety of 5. Deflection limits, generally an issue with FRP decks, are satisfied with the installed deck. ; Meanwhile, some combination of acoustic emission methods, infrared thermography and a newly developed traveling truck deflection ; method show promise for non-destructive evaluation of the deck in-situ and identification of damage such as delamination of the wearing ; surface or web buckling. However, such methods have shown variability and could be prohibitively labor-intensive. Therefore, further ; evaluation is needed if such methods are to be pursued.
