Multilevel BIM Analysis for the Assessment of Seismic Vulnerability of Masonry Buildings

The highly heterogeneous morphology of urban realities, derived from the development of buildings through different historical periods, characterizes the territory of the Italian countryside. The seismic risk widely exposes the Italian orographic context, so mitigation and reduction of the effects on buildings is a crucial topic. Vital support for the analysis of structural vulnerability is the representation models for underlaying the main vulnerability phenomena. This research aims to define an integrated multilevel tool capable of managing, analyzing, and representing the data's multiplicity, heterogeneity, and complexity necessary to evaluate the seismic vulnerability of masonry buildings in the historical centers. The information acquired through a process of knowledge and elaborated through parametric modeling systems (BIM) can determine the most likely collapse kinematics, therefore, to evaluate each structural unit's levels of seismic vulnerability. This paper shows the methodology tested on the case study of San Rocco Village in Sora (FR) and describes the results in detail.
