284 GNGTS 2022 Sessione 2.2 results by employing the smoothed spectra derived by the Italian Code (NTC18), provided that a record-to-record variability is derived a priori on natural records. In conclusion, the proposed approach constitutes a practical tool to carry out large-scale vulnerability assessments of existing buildings and, with this meaning, it could be useful as a decision-making tool in order to identify the most vulnerable area of a specific region and, thus, the priority of interventions. In this context, the presence of specific databases able to support the construction of reliable fragility curves are of particular importance. In this regard, the CARTIS project assumes a fundamental role, in that it pursues the objective of collecting the main characteristics of existing buildings, through the compilation of specific forms, and making them available to the scientific community.
