“…This problem is the same as that of a large class of non-structural components, such as mechanical and electrical hospital and laboratory equipment that can lose their functionality because of earthquake motions Makris 2009, 2010). Several efforts have been made in order to evaluate earthquake damage mitigation methods for museum objects and to develop new effective solutions (Sungay et al 2010). The rigid body mechanics is a key tool to evaluate the stability condition both in the case of freestanding single object (Sinopoli 1997) and in the case of an array of free-standing columns linked one to another by means of a simply supported rigid beam on the top, as in the ancient temples (Makris and Vassiliou 2013).…”

The role of friction in the seismic risk mitigation of freestanding art objects

The problem of reducing the seismic risk for art objects, that are the objects generally contained within Museums, is of great interest. The first studies were performed in Japan and were successively organized in a general framework by a research program performed at Southern California University and sponsored by the Getty Museum at Malibu, California. In these papers and in the following Italian studies, the theoretical models for the problem concerning vases and statues are based on the dynamic behavior of rigid blocks and have been deeply developed. Unfortunately, because of the great lack of experimental data, determinant parameters for the problem characterization (like the friction between two superimposed blocks or between the art object and the support plane) are often assumed without reference to real values derived from laboratory tests. This paper presents the results of a research program containing the experimental determination of the friction coefficient between the art object and the support (by means of a testing apparatus on purpose realized) together with dynamic tests performed on simple-shaped objects made of different materials. The dynamic tests were performed using an unidirectional shaking table and different supporting surfaces, so that the influence of different friction coefficients has been analyzed. © 2014 Springer Science+Business Media Dordrecht
