Abstract: In this paper, the dynamic characterisation of the civic bell-tower of Rotella (a small village in the Marche Region, Central Italy) is presented. The tower after being monitored, using four tri-axial piezo-electric accelerometers, and obtaining its dynamic characteristics, was modelled through a finite element software. The difference between measured and real values has been smoothed out by acting on all unknown parameters such as Young's moduli, thus obtaining a model with frequency differences, compared to reality, less than 5% and the MAC values between the modal shapes close to the unit.
