2. Conclusion Monitoring improves the evaluation of structures and infrastructures by allowing continuous verification of the structural performance. This cutting-edge structural analysis enables the identification of potential structural problems, enhancing the decision-making process to optimize the structure's performance. The examined three-spans box-girder bridge, which was retrofitted owing to ambiguities in the static scheme, was monitored in parallel to the interventions to ensure the structural response before, during and after the substitution of the bearings in the abutments. The comparison of the results of the FEM permitted the validation and certification of the testing, this is accomplished using the monitoring datasets as input of the finite element model. The case study demonstrates the impact of the new static scheme of the box-girder bridge, which is described simply as the replacement of the abutment bearings. In terms of bearings displacement, the structural performance agreed well with the performance obtained from the finite element model. As a result, it is proven that monitoring supports and enhances the decision-making process and management of bridges on a practical scale. References Bonaldi, A., E. Panzeri, and P.
