M r pecifically, earthquak simulations have been performed, y adopting both numerical and physical substructures, represented by an equivalent Multi Degree of Freedom for the building and a full-sc le Double Curved Surface Slider isol tor for the whol isolation system. A suite of seven natural seismic events has been selected, by ensuring the proper pectrum compatibility with respect to the hazard of the c nsidered case study structur , i terms of acc leration response spectrum. Special attention has be n focused on global results of the isolation layer, in terms of displacement an total force r sponses, together with the evaluation of the effective protecti n of the superstructure against eventual plastic defor ation dema ds. The response parameters returned by both the single-events an as average values among t e suite of selected events have b en red to the performance i itially estimated through fast design rules. Furthermore, Non-Linear Time History Analyses have been performed, by adopting the same analytical model of the building used within the hybrid tests algorithm, for sake of comparison between numerical and experimental simulations. © 2022 The Authors.

More specifically, earthquake simulations have been performed, by adopting both numerical and physical substructures, represented by an equivalent Multi Degree of Freedom for the building and a full-scale Double Curved Surface Slider isolator for the whole isolation system. A suite of seven natural seismic events has been selected, by ensuring the proper spectrum compatibility with respect to the hazard of the considered case study structure, in terms of acceleration response spectrum. Special attention has been focused on global results of the isolation layer, in terms of displacement and total force responses, together with the evaluation of the effective protection of the superstructure against eventual plastic deformation demands. The response parameters returned by both the single-events and as average values among the suite of selected events have been compared to the performance initially estimated through fast design rules. Furthermore, Non-Linear Time History Analyses have been performed, by adopting the same analytical model of the building used within the hybrid tests algorithm, for sake of comparison between numerical and experimental simulations.
