Dynamic signature versus temperature: a case study

A masonry belfry was the object of an experimental survey of the duration of days. The belfry was equipped with velocimeters located at different points inside the structure. The elaboration of the data collected under ambient vibration enabled to establish a correlation between the estimated modal properties and the temperature; such a correlation is acknowledged in the literature, but it is not very often characterized. After a brief description of the case study, the main results are reported and discussed.
