A BIM-BASED DIAGNOSTIC DIGITAL TWIN FOR PREVENTIVE SEISMIC RETROFIT OF OCCUPIED SCHOOL BUILDINGS

Abstract: Preventive seismic safety is a crucial topic in diverse territorial contexts, at national level, in Italy a major issue is represented by the central and south Italy, however in some areas in the north of Italy the seismic zoning has been updated increasing the level of safety of the areas and introducing a higher level of risk in the east part of the northern Italy.The paper presents a BIM-based Diagnostic Digital Twin framework supporting seismic vulnerability assessment, intervention design, and construction-phase safety management for occupied school buildings.
