LONGITUDINAL FORCES IN THREE OPEN-DECK STEEL BRIDGES

This paper describes the testing of 3 open-deck steel railroad bridges to measure longitudinal forces induced by high-adhesion alternating-current locomotives. Bridges tested include a 50-foot single-span riveted deck plate-girder bridge, a 122-foot dual-span welded deck plate-girder bridge, and a 400-foot four-span bridge made up of a 210-foot truss, 107-foot truss, and 39-foot and 42-foot beam spans. Analysis showed that the bridges generally resisted a significant portion of the applied longitudinal forces. Findings are discussed.
