| Abstract: |
The bridge under study is an arch bridge built in 1940, whose main structural element is a concrete arch without reinforcement that spans 80 m. Since it is one of the bridges with larger span constructed in Portugal during the Second World War period, involving a plain concrete arch, this bridge is an important Portuguese landmark. Due to the construction of a new hydroelectric power plant in the vicinity of the bridge, the bridge was equipped with a vibration based Structural Health Monitoring system, in order to continuously observe the impact of the construction activities on the structural integrity of this historical bridge. This paper presents the main characteristics of the structure and of its monitoring project, including a description of the monitoring hardware and software that is complemented with the analysis of the results associated with more than two years of continuous tracking of the bridge modal parameters. |
