Horizontal and Vertical BIM Interoperability Aimed at Seismic Vulnerability Assessment

A vital task of this millennium is to protect the existing heritage, also through the adoption of resilient management systems. In this framework, the organization of knowledge remains one of the critical points. For this reason, new methodologies and cross-disciplinary technologies are increasingly being chosen to optimize resources toward more sustainable interventions. Therefore, the ability to model the building geometry and behavior must be maximized through interoperable processes between Building Information Modeling and Finite Element Modeling methods aimed at the seismic vulnerability assessment. Setting up an integrated digitalization process is undoubtedly challenging initially but returns more significant benefits during the infrastructure life cycle. The interoperability tests' bi-directionality is essential for constantly evaluating activities to update data following facilities' modifications. The Modal Assurance Criterion indicator is used to assess the coherence of the models after possible simplifications introduced for non-linear state analyses
