323 GNGTS 2021 S essione 2.2 while a significantly better agreement was found between the proposed procedure and the experimental data. The proposed procedure appears promising for being extensively adopted on a greater number of buildings throughout large areas, in order to identify the situations in which SSI effects should not be overlooked. Acknowledgment This studywas carried out within the framework of the 2019-2021 ReLUIS-DPC research project funded by the Italian Civil Protection Department, as part of the Task 16.3 ‘Soil-Foundation- Structure Interaction’. Authors would like to thank the geologist Filippo Maurizio Cristallo for his availability and support. References Augenti N. and Parisi F.; 2019: Teoria e tecnica delle strutture in muratura.
