- W647525646 abstract "With the growth in both High Speed and Light Rail infrastructure projects worldwide there is a general requirement for accurate modelling of the interaction of the track with respect to any supporting bridge structures, and in particular, to ensure that any interaction between the track and the bridge as a result of temperature and train loading is within specified design limits. To accurately assess track-structure interaction effects nonlinear analyses are required to investigate thermal loading on the bridge deck, thermal loading on the rail if any rail expansion devices are fitted, and vertical and longitudinal braking and/or acceleration loads associated with the trainsets. For a complete rail track assessment, dynamic effects caused by the passage of trains that affect the structure itself must also be considered. The paper describes how rail track analysis for both high speed and general trainsets can be carried out according to the Union Internationale des Chemins de Fer (International Union of Railways) UIC774-3 Code of Practice with reference to the use of the LUSAS Rail Track Analysis software application. A comparison of ‘simplified’ and ‘complete’ UIC774-3 analysis methods is made showing that ‘simplified’ analysis results can lead to an over-estimate of the rail stresses when compared to ‘complete’ simultaneous analysis which considers the temperature and longitudinal and vertical train effects simultaneously. Automated modelling techniques and results and graphing capabilities are described and projects either built or under construction and on which the track-structure interaction software has been used to good effect are described." @default.
