Abstract
A program of non-destructive tests carried out on the two medieval stonecovered
façades of Palazzo Ducale in Venice is here described. It consisted of
direct and indirect sonic wave velocity tests on site and direct tests in the
laboratory on samples of the component materials. The program was set up after
a preliminary historic investigation aimed to raise useful clues on the geometric,
physical and mechanical features of the double-layered façades. The qualitative
information provided by the sonic testing procedure was assessed by mutual
comparison of the results; the reliability of the collected data was also kept into
consideration by assessing the distribution of results. The reported information is
going to be one of the first steps in a wide programme of multi-disciplinary
control of the façades.
Keywords: sonic wave velocity test, historic masonry, Venice.
1 Introduction
Preservation guidelines for the maintenance of monumental buildings require a
wide knowledge of complex general conditions, even when only a single
problem has to be faced. This is the case of Palazzo Ducale in Venice, one of the
most representative and valuable historic buildings of Italy. Like it happened to
other historic stone-covered façades (e.g. in Genova, Ferrara and Pavia), the
south façade of Palazzo Ducale (Figure 1) has recently suffered some unexpected
fall of material from the external stone covering of the south façade. Thus, the
Research Unit on Safety Assessment of Monuments at the IUAV University of
