Modeling and monitoring of the dynamic response of railroad bridges using wireless smart sensors
Railroad bridges form an integral part of railway infrastructure in the USA carrying approximately 40 % of the ton-miles of freight. The US Department of Transportation (DOT) forecasts current rail tonnage to increase up to 88 % by 2035. Within the railway network, a bridge occurs every 1.4 miles …

Determination of Lateral Resistance of Deck Tie Fasteners in Smooth Top Bridge Girders
… 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 systems that include …

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 …
