Increasing traffic volumes on aging structures force bridge operators to periodically evaluate infrastructure performance and assess safety using code and model-driven analyses. Of course, the integration of prediction and monitoring techniques improves the management of critical infrastructures providing meaningful information, but it is not easy to interpret hundreds of data. Nowadays, disruptive IoT technical advances suggest that data-driven approaches must be preferred to model-based. This is potentially harmful as it is not true that the more data collected, the more information gained on elements' condition and structural safety. Moreover, since technical decisions are supported by finite-element analyses it appears useful to profit from a priori knowledge of the structural behavior to support sensor placement and enhancing data interpretation. That way, the natural bottleneck to the amount of data imposed by code verifications is automatically considered enabling time and resource savings for superior bridge management.
