Multi‐level fatigue reliability assessment of reinforced concrete railway bridges
Structural Concrete, EarlyView.Abstract This paper presents a multi‐level reliability framework for assessing the fatigue life of reinforced concrete (RC) railway trough bridges subjected to cyclic loading. The framework incorporates increasing levels of analytical complexity and real‐world data in four steps. First, an analytical model applies S–N curves and the Palmgren–Miner rule

B‐WIM System Development for a Railway Bridge based on simulated data
ce/papers, Volume 9, Issue 2-3, Page 2971-2976, September 2026.Abstract Bridge Weigh‐In‐Motion (B‐WIM) technology can estimate axle loads and traffic parameters directly from structural responses, making it a valuable tool for structural health monitoring (SHM). Although there are developing benchmarks for road bridges, its application to railway bridges is limited due to unique challenges.

Dynamic effect of high speed railway traffic loads on the ballast track settlement [PDF]
, 2011 The traditional ballast track structures are still being used in high speed railways lines with success, however technical problems or performance features have led to non-ballast track solution in some cases.

The Impact of Russia–Ukraine War in Maritime Data
The World Economy, Volume 49, Issue 9, Page 1907-1923, September 2026.ABSTRACT This study analyses weekly port calls from 2019 to 2026 to evaluate the Russia–Ukraine war's impact on maritime trade. The data reveals clear structural shifts that Ukrainian traffic moved from high‐risk areas like Odesa to safer Danube River ports.

The Interaction Between Railway Vehicle Dynamics And Track Lateral Alignment [PDF]
This thesis examines the effect of vehicle dynamics on lateral deterioration of the track alignment. As rail traffic runs along a route, the forces imposed upon the track cause the ballast to settle, and hence the track geometry deteriorates.

Resin recovery and the use of computed tomography for quantitative image analysis of railway ballast
, 2014 Over its life cycle, railway ballast undergoes changes to its fabric structure due to train loading and maintenance (e.g. tamping). Understanding these changes and linking them quantitatively to the loading regime has the potential to inform improved ...
