Abstract:The type of structure selected for this research project is a four-spancontinuous concrete slab having GFRP bars for top and bottom mats and CFRPreinforcement for internal post-tensioning. The bridge is located in Rolla, Missouri(Southview Drive on Carter Creek). One lane of the bridge was already built using aconventional four-cell steel reinforced concrete box culvert. One lane and sidewalkneeded to be added and were constructed using FRP bars.This study includes design of the FRP portion of the bridge using existing codes,validation of the FRP technology through a pre-construction investigation conducted ontwo specimens representing a deck strip, and construction of the bridge; the resultsshowed how FRP, in the form of GFRP as passive and CFRP bars as active internalreinforcement, could be a feasible solution replacing the steel reinforcement ofconcrete slab bridges, and specifically the enhanced shear capacity of the slab due tothe CFRP prestressing.
