“…Thus, "integration" (i.e., integrating in one single model a large amount of multisource data) and "interoperability" (i.e., comprehensive and bi-lateral interaction with other software) should be considered the key words to apply to the HBIM approach [28]. The information regarding the seismic risk assessment of the church of Santa Maria Maggiore developed by Pirchio, et al [14] and the mechanical properties of the macro-blocks of the church defined using aggregated nondestructive test techniques (Pirchio, et al 2020b) were included in the multi-dimensional HBIMbased model as shown in Figure 5. The modeling could be performed with any BIM-based software (e.g., Autodesk Revit® or Graphisoft ArchiCAD®)…”

“…A holistic risk assessment methodology to guide the decision-making processes of the dioceses for prioritizing detailed assessments and retrofitting interventions was previously proposed [14]. Given the regional scale of this holistic methodology and its rapid application, the holistic methodology relied on simplistic, approximate methods to quantify structural vulnerabilities with the intention that churches with high holistic risk indices would subsequently be prioritized for more detailed vulnerability assessment.…”

“…The material mechanical properties (e.g., masonry compressive strength, shear strength, elastic modulus, etc.) often govern the in-plane and dynamic behavior of URM structures [15,16,17] and were determined for the case study church using an aggregation of non-destructive test techniques conducted by Pirchio, et al [18]. The geometric properties of the building components are the governing parameters for the out-of-plane behavior of URM structures [19,15,20].…”

Post-earthquake damage surveys systematically highlight the seismic vulnerability of monumental structures, calling for simple assessment procedures to address the design of effective retrofitting interventions. The structural complexity characterizing monumental structures, however, makes a reliable prediction of their seismic response a relevant challenge of engineering interest. Ambient vibration tests (AVTs) provide valuable support to achieve such a task, improving the knowledge of the actual dynamic behavior of the structure and, consequently, the reliability of the seismic assessment. In this context, the paper illustrates the integration of AVTs outcomes with the evaluation of the seismic performance of historic masonry structures by presenting the comprehensive application to a case study, the bell tower of the Saint Lawrence’s Cathedral in Genoa, Italy. The research combines the assessment of the global seismic response of the tower, investigated through a simplified mechanical model, with the local verification of the pinnacles placed at its top, referring to a displacement-based approach on a macro-block model. An extensive ambient vibrations measurement campaign carried out in May 2020 allowed for a comprehensive operational identification of the bell tower and its pinnacles, clarifying the ongoing dynamic interaction with the main body of the church. This valuable information was successfully employed, first, to accurately reproduce the actual constraint conditions induced by the church on the bell tower, a determining factor in the modeling of its global seismic response and, second, to reliably quantify the seismic amplification caused by the tower filtering effect to be used as the seismic input for the local verification of the pinnacles.
