A widespread approach for the prediction of the structural response as function of the ground motion intensity is based on the Cloud Analysis: once a set of points representing the engineering demand parameter (EDP) values is obtained as function of the selected seismic intensity measure (IM) for a collection of unscaled earthquake records, a regression analysis is performed by assuming a specific functional form to correlate these variables.

The protection of cultural heritage from seismic risk is an open issue due to the difficulties in finding technical solutions allowing a balance between their effectiveness and invasiveness. Among the available protection techniques, seismic isolation is one of the most suitable obtaining a significant performance improvement by acting on a limited portion of the structure. In this paper, it is shown an application of such technique on a reinforced concrete frame building cataloged as of historical interest by Italian Ministry of Cultural Heritage.

In Italy, in the 1920s, the contagious and difficult to treat disease of tuberculosis was still a terrible reality with often deadly outcomes. For this reason, in the mid-1920s, Eugenio Morelli, professor at the “Sapienza” University and specialized in pulmonary diseases, proposed the construction of numerous health facilities for the treatment and isolation of patients afflicted with tuberculosis.
