Sensitivity and Preliminary Analyses for the Seismic Assessment of Ardinghelli Palace

When dealing with the seismic assessment of historical buildings, a higher diversity in uncertainties related to construction details, geometry, and material properties is expected. Moreover, for the conservation of the monument a very low invasiveness degree is required during the investigation process. The procedures available in standards, based on the definition of a Knowledge Level for the whole structure, by following investigation plans that do not take into consideration the specific features of the building, may not serve efficiently in this context. These facts rise the need for a new procedure, rationally implemented to best fit the characteristics of the structure under investigation time by time. Within this context, the procedure based on a Sensitivity and a Preliminary Analyses proposed in Cattari et al. 2014 and Haddad et al. 2016/2017 is executed on Ardinghelli Palace in L’Aquila Italy. The sensitivity analysis is addressed to detect the uncertain parameters mostly affecting the structural response and defines what to investigate. While the preliminary analysis carries out a complementary role in identifying where in the structure shall we investigate, in order to set an effective investigation plan and increase the knowledge about it.
