The Leaning Bell Tower of Pisa (Italy) – built between 1173 and 1370 – is included within the list of the World Heritage Sites by UNESCO since 1987. In the past years, the Tower and the underlying soil have undergone many interventions in the attempt to reduce and stop definitely its inclination. The Tower was also equipped with a sensor network in-tended for seismic monitoring, which recorded the dynamic response of the monument un-der some far-field earthquakes.

The great availability of measurement systems permits to acquire quite easily data related to structural oscillations in operational conditions. This occurrence may permit to enhance our capability to data-driven computing using directly experimental data and pertinent constraints and conservation laws, such as compatibility and equilibrium, surely certain. In the paper, a methodology will be presented to furnish an analytical mechanical model of a suspension bridge in which the main parameters can be derived from vibration measurements.
