Description
Hao Xu, Kaize Xie, Jiayin Chen, Weixing Liu, and Hongsong Lin present a two thousand twenty-six engineering study of welded rail behaviour on a long steel truss railway bridge. Continuous rails crossing bridges stretch and squeeze as steel expands. Mixed passenger and freight loads complicate the forces further.
A three-dimensional model linked track, bridge, and piers under established interaction principles. Span counts, pier stiffness, bearing layout, rail type, and track resistance were varied systematically. Beyond eight spans, models could be simplified without losing accuracy. Pier stiffness strongly influenced rail braking forces, guiding safer design of ballastless track on bridges.
