RISDevelopment and Implementation of a Laser–Camera–UAV System to Measure Total Dynamic Transverse Displacement
Publisher: ASCE
Abstract: Railroad bridge inspectors are interested in measuring the maximum total transverse displacement of railroad bridges under trains, but these values are generally not easy to obtain in the field without sensors. Engineers ...
Real-Time Reference-Free Displacement of Railroad Bridges during Train-Crossing Events
Publisher: American Society of Civil Engineers
Abstract: Today, railroads carry 40% of the United States’ freight tonnage, and the demand for this service is expected to double in 20 years. The railroad infrastructure contains more than 100,000 bridges spanning over 225,000 km ...
Experimental Analysis on Effectiveness of Crash Beams for Impact Attenuation of Overheight Vehicle Collisions on Railroad Bridges
Publisher: ASCE
Abstract: Collisions between overheight semitrailer trucks with low-clearance railroad bridges are one of the leading causes for railroad traffic interruptions on bridges in the United States. Current sensing efforts to inform drivers ...
