    Figure 1: DFOS installation and strain signal output.<\/p>\n\n\n\n

    The methodology shows that DFOS generates comprehensive datasets, providing the detailed information required for thorough bridge assessment. Quasi-continuous measurements enable precise evaluation of bending moments, girder load distribution, boundary conditions and localized strain concentrations. This supports accurate displacement estimates and detailed crack detection, including complex interactions between the structural elements. Unlike traditional discrete-sensor methods, DFOS delivers spatially continuous data, capturing insights otherwise unattainable and giving engineers a more complete understanding of structural performance.<\/p>\n<\/div><\/section>\n\n\n

    Figure 2: DFOS crack identification and deflection prediction.<\/p>\n\n\n\n

    Overall, the results confirm that DFOS-based monitoring is a powerful, data-driven tool for improving bridge safety, informing maintenance decisions, and supporting sustainable management of existing concrete girder bridges. By integrating advanced data collection, interpretation and structural understanding, this approach enhances the reliability of safety assessments and opens avenues for further research.<\/p>\n<\/div><\/section>\n<\/div>\n<\/div>\n\n\n\n\n
