Vertical Dynamic Analysis of Ballastless Tracks on Train-Track- Bridge System [PDF]
MATEC Web of Conferences, 2020 In order to investigate the vertical dynamic response characteristics of train-track-bridge system on CWR (Continunously Welded Rail) under dynamic load of train on HSR (High-Speed Railway) bridge. Based on the principle of vehicle train-track-bridge coupling dynamics, taking the 32m simply supported bridge of a section of Zhengzhou-Xuzhou Passenger ...

Structural Concrete, Volume 24, Issue 3, Page 3558-3572, June 2023., 2023 Abstract For creep and shrinkage investigations, relatively small cylindrical specimens are generally exposed to constant climatic conditions. The derived mainly empirical prediction models are used for the calculation of large engineering structures with massive cross‐sections. In this paper, the expected values of the material models according to fib

Collision derailments on bridges containing ballastless slab tracks [PDF]
Engineering Failure Analysis, 2019 Train derailment on bridges is an infrequent event, yet when it occurs, it's usually catastrophic. These incidents can toss-out part of the derailed train from the bridge deck and collapse whole or a part of the bridge. Understanding the derailment mechanisms of trains on bridges and identifying the dynamic characteristics of bridges subjected to the ...
