Monitoring cultural heritage buildings: The santa Maria del carrobiolo bell-tower in Monza, Italy

The historic complex of Santa Maria del Carrobiolo in Monza (Italy) includes a church, a monastery, a bell-tower and other buildings, which were constructed at different times. A recent survey of the bell-tower highlighted that two sides of the tower are directly supported by the load-bearing walls of the apse and South aisle of the church. After the discovery of the weak structural arrangement of the building, static monitoring and dynamic monitoring systems were installed in the tower to address its preservation. After a brief description of the tower and the results of the preliminary survey, full details are given in the paper on the toolkits developed to process the raw data collected by the dynamic monitoring system and to automatically extract the modal parameters. Subsequently, the paper presents the first results of the continuous dynamic monitoring as well as the evidences provided by the static monitoring.
