Analyses and modeling of track transition site responses from instrumented bridge approaches
"Railroad bridge approaches, which connect open track to bridge structures, commonly experience recurring defects, such as broken superstructure components, excessive deformation, and ballast degradation that may require frequent maintenance. Such deformations or simply referred to as ""bumps at …

Track model for predicting dynamic responses of railroad bridge approaches
… focused on the development of a novel train-track-bridge model that can analytically tackle the difficult problem of a railway track transition zone and effectively simulate the dynamic response of a bridge approach subjected to moving train loads. The scope of the research encompassed …

Integrated computational and experimental framework for the assessment of railroad ballast life-cycle behavior
… gradation, is an essential layer in the railroad track substructure. Functions of ballast include facilitating load distribution and drainage, maintaining track geometry and track stability, and providing track resilience and noise absorption. Throughout its service life, ballast goes through …
