Entwicklung neuer Nachweiskonzepte für vertikale Schienenstützpunktkräfte an Bauwerksfugen bei Fester Fahrbahn mithilfe von Grenzwertbetrachtungen

摘要

For railway bridges with slab track, the vertical rail support forces on bridging joints must be designed according to attachment 29 of the DS 804 guideline (published in 2000). The specifications according to this current design standard have been derived on the basis of a linear force-deformation behavior. Due to the nonlinear stiffness behavior of newly developed high-performance supports for slab track systems, these design provisions need to be updated and questioned critically.
