Abstract

The Italian school buildings asset consists of over 40,000 units. The most (about 60%) were built before the introduction of the national standard on school buildings and constructions in seismic areas. The opportunity to define a methodology to assess the condition of an infrastructure before and after a seismic event is therefore of particular importance, both for a screening of the existing assets and for the damage assessment after the event. Before the event, it may allow to establish priorities of intervention in the field of seismic risk reduction. Furthermore, after the event, it can be crucial to recover the infrastructure. The proposed BIM-based (Building Information Modelling)approach includes static and dynamic non-destructive testing and structural finite element analysis of the existing building. Guidelines for BIM modeling will be drawn up in order to give indications to BIM modelers and to obtain a BIM model that can be straightforward used for dynamic structural analyses. It may allow to assess the seismic fragility of the existing infrastructures in terms of the standard vulnerability coefficient. Furthermore, subsequently to the seismic event, it may be useful to identifying incipient damage conditions that are not directly detectable, e.g. by Operational Modal Analysis (OMA) techniques. An existing building school in North Italy is analyzed as a case study to test the proposed framework.
