Apparati storico artistici e miglioramento sismico nel restauro post-sisma. Nuovo approccio metodologico,

“The restoration of historical, artistic and decorative features and the seismic improvement of the structures are interventions that interact between themselves…” [1] and the project of the interventions must be integrated and cannot be seen separately. For the restoration of historical artistic heritage, the MIBAC guidelines provide for the Artistic Limit State that needs to be deepened taking into account the strong connection with the structure. Seismic safety is a consequence of these aspects and the analysis of seismic risk should include a critical reading of all the vulnerability indicators of the structure and of the artistic assets connected to it. The authors developed a methodological approach experimented in the restoration and seismic improvement of some historical buildings located in L'Aquila and damaged by the earthquake of 2009, including the Church of “Santa Maria della Misericordia” (AQ), where compatible interventions with the preexistence were identified. At the same time, these interventions can guarantee the preservation of the historical building and the safety of all its components. This contribution therefore intends to illustrate the methodology developed, then verified in the aforementioned case study.
