Calculational methodology evaluates viaduct behavior under seismic actions, suggesting improved design approaches.
Objective: to account for the behavior of continuous welded rail (CWR) on high-speed railway viaducts under seismic actions along the track axis. Methods: development of a calculation methodology that includes a behavior analysis of the “bridge — CWR” system for span-type viaducts with continuous welded rails under longitudinal seismic actions. Results: calculation procedures for viaducts with continuous welded rails under longitudinal seismic forces. Practical significance: provision of a framework for the design and analysis of viaducts with continuous welded rails under longitudinal seismic actions.
