Dynamic monitoring and model updating of the Leaning Tower of Pisa
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 intended for seismic monitoring,which recorded the dynamic response of the monument under some far-field earthquakes.In this study,the dynamic response of the Tower recorded under some recent seismic event has been analyzed in the time-and frequency-domain,thereby allowing the identification of its main vibration modes.Furthermore,a simplified finite element model of this valuable monument has been developed taking into account the soil-structure interaction.This numerical model has been used to perform a large sensitivity analysis and to calibrate the dynamic impedances at the base of the structure.
