In-situ load testing of an ancient masonry structure using fibre optics

This study highlights the deployment of the New Smart Hybrid Transducer (NSHT) for structural health monitoring (SHM) through an infield test performed on the ancient Santa Maria delle Grazie complex, showcasing its effectiveness in non-invasively monitoring the structural integrity of cultural heritage sites. By leveraging optical fibre technology, the NSHT provides precise, continuous strain and temperature data, overcoming the limitations of traditional monitoring methods. The research validates the NSHT's performance through in-situ tests, comparing its outputs with conventional instruments and a finite element model to underscore its accuracy and reliability in real-world conditions. This innovative approach enhances the understanding of structural behaviour and addresses the challenges of integrating advanced monitoring systems into heritage conservation.
