LA CARATTERIZZAZIONE TECNOLOGICA PER LA MITIGAZIONE DEL RISCHIO SISMICO. IL CASO STUDIO DELLE CHIESE DEI " SASSI DI MATERA " . TECHNOLOGICAL CHARACTERIZATION FOR THE MITIGATION OF SEISMIC RISK. THE CASE STUDY OF CHURCHES OF " SASSI DI MATERA "

The conservation of historic buildings cannot be independent of the knowledge of its constitutive features such as: materials, constructive techniques, structural characteristics and building evolution, representing a crucial point for the assessment of seismic risk. In this paper, a procedure for the typological characterization and two simplified procedures for seismic risk assessment are described and critically applied to case studies of churches belonging to the "Sassi of Matera", the historic center of Matera town protected by UNESCO. This methodology is intended to be used at a territorial scale for the planning of preventive conservation of cultural heritage and seismic risk mitigation projects. The obtained results are shown and compared among them, highlighting the aspects that characterize their seismic vulnerability.
