• Abstract:
  The present project had two main objectives, to experimentally and analytically investigate a bridge deck reinforced with glass ; fiber reinforced polymer rebars, and to perform durability tests on four rebar types. ; An analytical investigation was performed using the finite element software ANSYS for both the actual bridge deck, and for the ; reduced size laboratory experiment. In addition, laboratory experiments were also performed on an 11 ft long bridge deck model ; built inside the structures lab. Except for the length of the girder-deck model, the true scale was used for every other dimension. ; Three different tests were performed on the model, and the test data verified the analytical results. Once completed, this bridge ; located in Macon County was instrumented and tested using two loaded tandem trucks. ; For the durability testing, four different types of Glass Fiber Reinforced Polymer (GFRP) reinforcement provided by different ; rebar vendors were evaluated under exposure to an alkaline environment at different temperatures. For the moisture tests, a total ; of 96 specimens were monitored for changes in length, diameter, and weight. A total 128 unscathed samples and 64 “nicked” ; samples – simulating defects to the rebars that might occur on the field site – were tested in tension to determine the rate of ; degradation in tensile properties. Concrete cylinders were poured, and 168 pullout specimens were tested (84 at 5Øb and 84 at ; 8Øb).
