Development of an efficient connector system for fiber reinforced polymer bridge decks to steel girders
Fiber reinforced polymer (FRP) is a promising material system for use in bridge construction. One of the most likely uses of this material in future bridge is FRP bridge decks over steel or concrete girders. The primary purpose of this paper is to describe the develpment of a shear stud-type connection for FRP decks to steel stringers. Construction of this connection would involve: Welding the threaded studs to the girder, placing the FRP deck with the sleeves installed, placing and thightening the nuts on the stud to secure the deck, and then covering the sleeves in some manner, perhaps a FRP overlay or cap made to fit inside the top sleeve. The new connection was subjected to a series of tests involving individual connectors. As a result of the experimental testing, the satisfactory performance of the proposed connection for FRP bridge decks to steel girders was verified. The shear strength of the connection is expected to significantly exceed the shear force that the connection is expected to resist at service level loads. The experimental tests of the reduced scale bridge verify that the connections perform well at anticipated service level loads.
