Abstract (EN):
The present work describes the dynamic monitoring activity developed in a railway bridge that crosses the Tua River, in Portugal, a centenary steel riveted deck with a length of 180 m, supported by five masonry piers. Owing to the present construction of a new hydroelectric powerplant in its vicinity, the bridge was equipped with a monitoring system, in order to observe if the construction activities would interfere with its structural integrity. This paper characterizes the monitoring project, starting with the description of the system hardware and software that is then complemented with the analysis of the results from the last four years of continuous tracking of the bridge modal parameters.
