Cover Story: This paper presents two ambient vibration tests performed on a fortified masonry tower in the Marche region of Italy, carried out one year apart. At the start, the dynamic parameters obtained during the two experimental campaigns are compared to identify possible changes due to damage or different environmental conditions. In addition, the steps carried out for the numerical calibration of the tower’s experimental behavior are shown. The match between the numerical model and the experimental data is evaluated through the absolute frequencies’ errors and the modal assurance criteria between the modal vectors. View this paper
