Abstract. The paper presents some results of the continuous dynamic monitoring program carried out on the tallest historic tower in Mantua, Italy. This project follows an extensive diagnostic investigation aimed at assessing the structural condition of the tower after the Italian earthquakes of May 2012. A simple dynamic monitoring system was permanently installed in the upper part of the building and automatic modal identification was performed. The results allow to evaluate the effects of changing temperature on automatically identified natural frequencies, to verify the practical feasibility of damage detection methods based on natural frequencies shifts and provide clear evidence of the possible key role of continuous dynamic monitoring in the preventive conservation of historic towers.

“…Modal properties are often among the first few quantities to be identified in a structural vibration project. They are often examined to provide information for structural model updating, structural modification, damage detection, or more generally, structural health monitoring [1][2][3][4].…”

“…Within this context, vibration-based dynamic monitoring can be considered as a quite novel approach, if applied to cultural heritage. In particular, while the use of Operational Modal Analysis (OMA) techniques is well-established for performing dynamic structural investigations and/or implementing continuous monitoring of relatively new slender structures [8,9], their application in the context of heritage monumental buildings is far less common. A few documented applications of vibration-based monitoring to monumental buildings are however available, whereby some literature studies have proposed the use of OMA techniques for the dynamic identification of masonry civil and bell towers [10,11,12].…”

Abstract. This paper newly proposes the use of ambient vibration testing, vibration-based continuous dynamic monitoring and automated modal identification for structural assessment of monumental masonry domes. The final purpose of this research is the development of a general methodology for online structural health monitoring of large domes, enabling early detection of damages caused by low return period earthquakes, in a general framework of preventive conservation and heritage resilience. The case study considered here is the dome of the Basilica of Santa Maria degli Angeli in Assisi, recently added to the World Heritage List of Unesco. The basilica is located in the center of Italy and it was built between 1569 and 1679 on the design of the architect Galeazzo Alessi. It consists of a latin cross plan, with 126 m and 65 m dimensions, with a nave, two aisles and a semicircular apse. At the intersection between the transept and nave the building hosts the Porziuncola, a little ancient chapel, symbol of Franciscan spirituality and pilgrims destination since the construction of the basilica.In order to preliminary assess the structural behavior of the dome, several dynamic experimental investigations have been carried out and ended with the installation of a simple vibration-based monitoring system, based on the use of a few high sensitivity accelerometers, placed at the top and the base of the drum, as well as temperature and humidity sensors. This paper presents and discusses the first results of the vibration-based monitoring of the drumdome system, demonstrating the potential for using similar approaches for the preservation of this special kind of historic structures. 5359
