Role of the new technologies on the artifacts seismic vulnerability the case of the Bartolomeo Ammannati's "Fontana di Sala Grande", National Museum of Bargello court- Florence

In these decades the seismic vulnerability of buildings have been widely investigated, and many different approaches have been developed for their preservation. Museums' collections, instead, achieved interest from research communities only in the very last years. Artifacts can easily be both valuable and seismic vulnerable, since they can present irregular shape - not easy to be numerically represented - and fragile material. The need to check the seismic vulnerability of artifacts has induced the developments of new techniques aimed at representing their shape and mass distribution through not-invasive approaches, and at simulating their seismic response by means of numerical analyses. In this work a laser scanner analysis has been applied to create a three dimensional digital model of the Bartolomeo Ammannati's "Fontana di Sala Grande", currently located under the vaults of the National Museum of Bargello court, in Florence. The set of data produced can be visualized in interactive modes, creating a sort of "new reality" showing the possible events according to earthquake phenomena, a kind of reality no one want to see getting real, but at the time useful to know for taking countermeasures. Furthermore, the 3D model has been adopted to perform a structural analysis aimed at checking the seismic response of the sculpture complex. The seismic input assumed in the analysis has been found by implementing the seismic hazard of the area, according to the current Code classification, through a proper soil modeling of Florence, defined after the amplification factor distribution. The research, developed by joining different knowledge and fields, is an example of the importance of a multidisciplinary approach for preserving artifacts and museums' collections.
