Site characterization and preliminary ground response analysis for the monumental Complex of SS. Annunziata in Sulmona, Italy

The paper presents the preliminary results of a multidisciplinary study performed in the area of Sulmona (L’Aquila, Italy) where the historical building Complex of the SS. Annunziata is located. The Complex was significantly damaged by the 2009 L'Aquila earthquake and the damage observed to the rear of the buildings in the monumental Complex was more severe than those of the front. To verify whether the subsoil local conditions can explain the distribution of the observed damage, studies of ground response have been planned at the site where SS. Annunziata Complex is located. In the paper, after a general overview of the Sulmona basin and the SS. Annunziata Complex, the results of the survey carried out in the study area are described and analyzed, aimed at defining the geotechnical model. The results of numerical 1D analyses performed on soil profiles, representative of the subsoil conditions both at the front and back of the historical Complex, are also presented and compared.
