GNGTS 2016 S essione A matrice 41 possible to determine the construction age, number of storeys, and average storey surface of masonry and RC structures, see Fig. 1. The graphs show that masonry structures have been almost built before 1971 while RC ones are related to periods after 1961; most of the structures have 1 or 2 storeys and an average storey surface in the range 170-899 m 2 . In terms of usability assessment, about 59% of the masonry structures were assessed with usability rating A (i.e. usable building, no significant damage), about 22% B (i.e. no significant damage on structural members) and about 19% E (i.e. significant damage on both structural and non-structural elements), see Fig. 2. On the RC framed structures the percentage of usable structures was greater than that of masonry ones, about 78% of structures with usability ratingA. The most common damage was detected on non-structural members (i.e. partitions and ceiling), see Fig. 3. The usability rating B and E involved 18% and 4% of structures, respectively.
