In this paper, dynamic analyses and field measurements of a tied arch railway bridge is presented. Excessive vibrations of the hangers were obtained, caused by resonance during train passages. The resulting increase of the stress level and number of stress cycles were shown to decrease the fatigue service life significantly. The most critical section is a threaded turnbuckle connection of the h...

In major cities around the world, urbanization and rising land prices have been driving an increase in real estate development adjacent to, and above in many cases, railway lines and other transportation corridors. Structure-borne sound and vibrations from traffic can be are annoying to human occupants; if high, they can also be disruptive to operation of manufacturing facilities, medical facil...

Abstract The present work addresses the problem of unified methodology use for vibration analysis caused by various anthropogenic sources. experimental part paper contains and results comparison vibration, induced freight train passages hammer percussion. Ground vibrations are important civil engineering objects condition since is transmitted through ground to foundation structure. can also be ...

This article presents a numerical study that aims to explore the dynamic behavior of railway bridges under vibrations induced by heavy-haul traffic. For this purpose, finite element code can conduct moving load and mass analysis single span was developed. The software validated comparing response analytical solution for various speeds. benchmark bridge train showed interplay between natural fre...

Higher train speeds and heavier axle loads trigger elevated stresses vibrations in the track, potentially increasing track deterioration rates maintenance costs. Alternative forms made of combinations reinforced concrete asphalt layers have been developed. A thorough understanding slab tracks is needed to investigate performance. Thus, analytical numerical models developed validated by many res...
