Redesign of a historical masonry stronghold incorporating a base isolated floor

The central wing of an earthquake-damaged historical castle in Italy is redesigned in this study, by assigning it a new destination as a museum. Traditional techniques are used for rebuilding the masonry walls and the wooden floors. At the same time, a base isolation solution is adopted for the ground floor, where the main exhibition hall, including two marble statues, is accommodated. The seismic performance of the statues is comparatively assessed for the base isolated floor and a conventional fixed base configuration, by referring to three limit states postulated herein, represented by the attainment of rocking, damage and collapse response conditions.
