Implementation of a fiber Bragg grating sensor network for structural monitoring of a rehabilitated metallic bridge

A fiber Bragg grating (FBG) sensor network was successfully implemented to monitor the structural health of the rehabilitated upper deck of Luiz I Bridge. The study demonstrated that FBG sensors can provide real-time, precise measurements of strain and deformation in metallic structures, offering a robust solution for long-term structural monitoring. This approach is particularly valuable for bridges undergoing significant modifications, such as the integration of metro lines, which introduces complex loading conditions. The findings highlight the potential of FBG sensor networks to enhance safety and maintenance strategies for critical infrastructure, ensuring their longevity and performance.
