Within this context, structural health monitoring techniques, like those based on ambient vibrations under operating conditions, represent powerful tools for evaluating the dynamic behavior of existing structures. The presented methodology is particularly interesting for historic and monumental buildings due to its non-invasiveness. This work illustrates the installation of a monitoring system in the historical masonry Town-Hall of Borgo Val di Taro, dating back to the fifteen century, for its ambient vibration modal identification. The so collected data are then used for the construction of a refined numerical model for the simulation of the dynamic response of the building, and for the updating of its parameters. A comparison between numerical and experimental results is finally provided.
