Abstract

The Italian school buildings asset consists of over 40,000 units. The most (more than 60%) were built before the introduction of the national standard on school buildings and constructions in seismic areas. The present research aims to implement a methodology that consists in an informative modelling for seismic risk analysis. The objective of the activity is to provide the policy makers of an innovative and useful tool for screening the existing building stock, in order to define the priorities of intervention. The research is divided into several parts. The paper firstly investigates a structured way to collect data for an existing school building, through non-destructive tests (impact hammer - sclerometer, pacometer, thermal camera, accelerometric network) for the reconstruction of the information heritage related to the structures. The existing BIM (building information model) is then integrated with the structural data. The usefulness of implementing the actual BIM LOD (level of detail) or an higher detail level that can represent the new state of knowledge is also investigated to prepare a finite element model. The subsequent on field acceleration measures are employed both to evaluate the structural modal characteristics and to validate the finite element model. The computation of the vulnerability coefficient of the structure in accordance with the new Italian standard is the last step of the analysis.
