The paper describes the methodology applied to the tallest historic tower in Mantua, the "Gabbia" tower, to assess its state of preservation after the earthquakes of 29 May 2012. An extensive investigation program including visual inspection, sonic and flat jack tests, ambient vibration testing and structural modeling has been planned to support the future preservation actions of the tower. The paper summarizes the information provided by visual inspection and dynamic tests, clearly highlighting the poor structural condition and the high seismic vulnerability of the upper part of the tower. Subsequently, the permanent dynamic monitoring system installed on the tower with early warning purposes is described and some results are presented and discussed.

Abstract
The paper describes the methodology applied to the tallest historic tower in Mantua, the "Gabbia" tower, to assess its state of preservation after the earthquakes of 29 May 2012. An extensive investigation program including visual inspection, sonic and flat jack tests, ambient vibration testing and structural modeling has been planned to support the future preservation actions of the tower. The paper summarizes the information provided by visual inspection and dynamic tests, clearly highlighting the poor structural condition and the high seismic vulnerability of the upper part of the tower. Subsequently, the permanent dynamic monitoring system installed on the tower with early warning purposes is described and some results are presented and discussed.| File | Dimensione | Formato | |
