Abstract
The paper summarizes the main aspects of the in-progress PhD research that wants to provide supporting empirical-experimental analyses, deepening the aspects that can affect structural behaviour. The research will study emblematic cases in the Etna area, after having carried out a census and a typological classification never pursued previously. To validate the obtained results, the thesis will compare these buildings with the bell towers in the Valladolid area. The comparison will check whether similar buildings (located in different geographical areas) are characterized by a different durability from that on our national territory.
