“…Each geometrical model was simplified through the software MeshLab [29] in order to reduce the number of polygons describing its surface; then it was further changed, by introducing a set of nodes in the volume inscribed by the surface, in order to obtain a volume model. Figures 1, 2 and 3 show, for the three casestudies, the main information regarding the rigid block and the FEM models, whilst in [15,28,30] In the rigid blocks analysis, the collapse condition is assumed at the overturning of the sculpture occurred as a consequence of the seismic input. Each sculpture has been modeled as a single rigid block, neglecting the possible interface between the pedestal and the upper sculpture, such as the vertical component of the earthquake.…”

The art goods represent a priceless asset of the cultural and artistic identity of communities. Nevertheless, the seismic performance of museums' content is only rarely checked, despite the several losses occurred in the last earthquakes (Emilia Region 2012, Aquila 2009, Central Italy 2016). As a consequence, risk mitigation and management have been paying an increasing attention to artistic and cultural goods. Such artifacts, despite presenting an intrinsic vulnerability-due to their irregular shape, slenderness, fragility-rarely are adequately protected from earthquakes. The research project "RESIMUS" has developed in this scenario, and it focuses on the seismic vulnerability of the collections exposed in the Museum of Bargello in Florence. A special attention is paid to the role played by the staging on the seismic performance of the artifacts. The Museum of Bargello represents a privileged case-study, both for the importance and the value of its collections and for their staging variety. The staging adopted in the Museum, indeed, presents different types, materials, ages and dynamic properties, representing a special example of site-specific outfitting. The research project has involved different scientists and disciplines, providing results which concern the laserscanner survey of the objects, their classification according to the main mechanisms of collapse, the site-specific seismic input and the finite element modeling of some case-studies.

“…Obviously, to define the solidity of the display system we should investigate the kind of connection between object and base and the intrinsic features of the latter. To be precise, we should apply the study we pursue on the Ammannati's fountain at the Bargello [28]. The outstanding setup of the Pietà Rondanini in the Castello Sforzesco in Milan by BBPR took into consideration the relationship of one piece with the collection, the room, and the site.…”

The paper presents part of a work-in-progress research on earthquake damage mitigation for museum collections, focusing on the museographical aspects. The essay is part of the research project RESIMUS -Resilience Museums, developed by a group of researchers of DIDA of the University of Florence. We present two fundamental museographical tools: the drawing as an instrument of study, and the study of coherent museographical references. The paper tries to merge the literature on proper devices for the seismic reliability of artifacts and the updated museographical literature, in order to develop a framework where the seismic prevention comprehends the entire exhibition design.

“…It is well known that the reliability of the numerical analysis depends on the assumptions made in the analysis. Some numerical analyses were performed within the research project "Resimus" [4,5,[15][16][17] on the statue "Cerere" by Bartolomeo Ammannati. Two advanced Finite Element models have been adopted for representing the artifact.…”

The protection of art goods is an important issue of the seismic engineering. Artifacts are often made by fragile and ancient material, and they can easily present irregular shapes and high slenderness. In these years many contributions have been devoted to their analysis, based on numerical models having different complexity and computational effort. The Finite Element Models represent the most common and versatile approach for the representation of artifacts. Nevertheless, their reliability depends on the numerical assumptions made for the analysis, which requires a wide number of information regarding the dynamic behavior of the artifacts, such as the friction between the analyzed object and its support, the effective damping, the inelastic involvement of material, etc. In this work an experimental campaign has been started aimed at determining the main factors which affect the dynamic representation of artifacts through FEM analysis and simplified models. A large number of experimental tests, both static and dynamic, have been performed, by adopting both real and reduced scale objects.
