Abstract: The number of bridges worldwide is extensive, making it financially and technically challenging for the authorities to install a structural health monitoring (SHM) system and collect large quantities of data for every single bridge. Transfer learning has gained relevance in the last few years to extend the SHM concept for most bridges while minimizing costs with monitoring systems and time with data measurement. It can be especially suitable for those types of bridges that are structurally similar and replicated extensively, like overpasses and bridges integrated into highways. In the presentation, the effectiveness of transfer learning methods is compared through the classification performance using real-world monitoring data sets collected from the Z-24 Bridge in Switzerland and the PI-57 Bridge in France.
