Determination of Lateral Resistance of Deck Tie Fasteners in Smooth Top Bridge Girders
… capacity and spacing requirements of deck tie fasteners in curved railroad bridges with smooth top girders. In railroad bridge design, required lateral resistance dictates the spacing of deck tie fasteners. Currently, no provisions exist to aid in the calculation of lateral resistance for …

Railroad Tie Lateral Resistance on Open Deck Plate Girder Bridges
On open-deck railroad bridges, the crossties (sleepers) are directly supported by the bridge superstructure and anchored with deck tie fasteners such as hook bolts. These fasteners provide lateral resistance for the bridge ties. Currently there are no provisions to assist in the calculation of …
