GNGTS 2023 - Atti del 41° Convegno Nazionale

Session 2.2 GNGTS 2023 (Albarello et al., 2021) obtained in the framework of DPC-ReLUIS project 2019-2021 were considered. In particular, seismo-stratigraphical and geotechnical data from Sesimic Microzonation studies of 1689 Italian municipalities were used to perform 1380600 1D equivalent linear numerical simulations: the resulting acceleration response spectra were used to compute AFs considering Eq.1, where in this case Sa and Sb represent output and input motion response spectrum respectively. For each of the simulated profiles, AF_NTC18 value is then retrieved estimating the soil class and considering the municipality of the data origin. Finally, the two datasets were compared following the approach mentioned above.
