Abstract (EN):
Within the context of fatigue assessment of metallic railway bridges, the phenomena of local fatigue can be of major importance to the safety evaluation of this kind of structure. Therefore, this paper reports research work carried out to characterize the dynamic and fatigue behaviour of the Portuguese Trezói riveted railway bridge, presenting studies concerning the assessment of the local vibration characteristics directly associated with local fatigue problems, and also the calculation of the residual fatigue life of the bridge. This study was supported by a long term monitoring of key elements and details and it was conceived to measure critical stress patterns using strain gauges placed in strategic locations. This research was developed by the Laboratory of Vibrations and Monitoring (ViBest) of FEUP, in cooperation with the Portuguese railway administration, in the framework of the European FADLESS Project. © Civil-Comp Press, 2012.
