4. Conclusions Distributed fiber optic sensors offer valuable insights into the performance of post-tensioned girders. Employing a well-designed monitoring system with these sensors enables periodic assessment of strains and displacements in bridge structures, facilitating evaluations of their technical condition. It can provide comprehensive information on deformation changes throughout the entire length of the structure. Moreover, the DFOS technique allows for the investigation of localized phenomena, including crack detection and internal damage identification. Data obtained from DFOS can be processed using appropriate algorithms to accurately determine crack widths and deflections.
