ABSTRACT

Most of the schools in Italy were built before the introduction of the legislation on structural design in seismic areas. Approximately 25,000 buildings are therefore not adequate to current standards and require in-depth assessments of the seismic safety of structures. This research aims to implement a methodology consisting of the use of information modelling for seismic risk analysis. To assess seismic vulnerability, it is also necessary to analyze the seismic hazard. Two approaches are then tested: the first one is related to structural BIM modeling and structural analysis where information are collected through visual screening during inspections and through the study of existing documentations. The second is a more in-depth approach that includes static and dynamic non-destructive testing and structural FEM analysis. The two models were tested on the main building of a middle school in Milan (Italy).
