Federated parametric models for seismic risk analysis in existing buildings

The paper deals with the results of a research activity related to the application of BIM technologies for the analysis of seismic risk in existing school buildings. Digital modelling was carried up in phases, organizing the various disciplinary models according to a federated model approach. The case study highlighted potential and criticality in the generation of integrated architectural, structural and analytical models, and in the development of the information data flow, on which the reliability of the simulations of structural behavior depends.
