ASTM and FABRE together for the monitoring of bridges and viaducts

The ASTM group has stipulated a research agreement with the FABRE consortium to develop an innovative technological platform for the instrumental monitoring of bridges and viaducts. The research, which will last four years, will lead to the development of an advanced system for managing the risk of the group’s bridges at various levels, including the static, foundational, seismic, geotechnical and hydraulic aspects.
The system will allow for the centralized management of predictive algorithms based exclusively on data for the recognition of structural behavior anomalies on the basis of instrumental monitoring systems including sensors of various kinds (static, dynamic, physical, mechanical, environmental, etc.) with machine learning logics and artificial intelligence.
The same system will also make it possible to activate more specific controls and algorithms, at the level of the single work recognized as critical, by applying monitoring logics based on models with threshold controls or analysis strategies based on the continuous updating of digital twins of the work. For bridges where there is a known evolutionary phenomenon capable of changing the level of safety of the work over time, algorithms will also be provided for the real-time calculation of the reliability index of the work. The platform will thus be fully consistent with the requirements of the bridge guidelines and with ANSFISA’s technical indications for the instrumental monitoring of bridges and viaducts as part of the measures envisaged by the PNRR.
During the research, which takes the form of a unique technical-scientific effort in terms of size and objectives both on the national and international scene, FABRE will assist the concessionaires of the ASTM group (Autostrada dei Fiori S.p.A., Autovia Padana S.p.A., S.A.T.A.P. S.p.A., Autostrada Asti- Cuneo S.p.A., Società Autostrada Ligure Toscana S.p.A, Società Italiana Traforo Autostradale del Frejus S.p.A., Società Autostrade Valdostane SAV S.p.A.) in collaboration with SINA and SINELEC in the development of monitoring logics and algorithms and in the pilot application of the strategies developed to at least 20 bridges managed by the group.
