Exposure and seismic vulnerability of masonry buildings grouped in aggregate of a typical historical centre in the Basilicata region of Italy

The proposed study focuses on the typological and structural characterization of masonry building aggregates located in the historical centre of Atella, a small town in the district of Potenza in the Basilicata region of Italy. The data regarding building exposure were collected using the CARTIS form in the framework of Working Package 2 “Inventory of existing structural typologies” of the Italian DPC-ReLUIS project, which relates to the predominant structural taxonomies identified on-site. Subsequently, the surveyed structural information was used to carry out a preliminary vulnerability and damage analysis for the investigated urban area. Finally, the main outcomes of the study were provided in terms of the Building Typology Matrix (BTM) vulnerability functions, emphasising the differences in terms of expected susceptibility to damage of the identified CARTIS typologies.
