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 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.

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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
