To date, the spring stiffness of resilience pads was mostly evaluated based on conventional (site measurement and laboratory tests) methods. Most studies in the past analyzed the effects of the deterioration of resilience pads on track damage. To examine...

Dynamic response analysis of a train?track?bridge (TTB) system is a challenging task for researchers and engineers, partially due to the complicated nature of the wheel?rail interaction (WRI). When Newton?s method is used to solve implicit nonlinear fini...

In the transition zone of railway tracks, track irregularities occur frequently due to differential settlement, which arises from the difference between the vertical supporting stiffness of the abutment and the backfill. This is disadvantageous because i...

A bridge approach, an essential component connecting a relatively rigid bridge and a more flexible track on subgrade soil, is one of the most common types of track transition zones. The tracks on a bridge deck often undergo significantly lower deformatio...
