CT Girder with FRP Shear Studs – Strength & Fatigue Testing

This project focuses on the assessment of the fiber-reinforced polymer tub girder (CT girder) with precast concrete decks and new, fiber-reinforced polymer (FRP) girder-deck shear connectors. This will extend the application of this new bridge technology by modularizing construction and the additional use of composite materials. The new FRP shear connectors, when used with FRP rebar for the deck reinforcing, will completely eliminate steel and therefore all corrosion in the bridge superstructure. The project will also include the fatigue testing of a full-scale girder, which has not been performed to-date. This research project will employ both large-scale and smaller-scale experiments.
