Performance assessment of steel truss railway bridge with curved track

Non-destructive Structural Health Monitoring techniques can be incorporated into bridge integrity management by assessing structural conditions. This paper describes a performance assessment of steel truss railway in Bratislava using vibration-based as further part maintenance addition to standard visual inspections. To obtain the necessary data, multipurpose measuring system was used. Various types data were measured, e.g. accelerations, strains, and displacements. The advantage that traffic over not restricted, even though carries only single curved track. Two test campaigns conducted assess bridge. One campaign devoted ambient vibrations order perform operational modal analysis, second carried out measure strains displacements during train passage. results show successful identification structure vibrations; finite element model verified validated comparison displacements, well parameters. According obtained, health investigated satisfactory.
