Mechanical characterization of particular masonry panels in Tuscany

The knowledge of masonries’ mechanical parameters is an essential requirement for a reliable structural assessment on existing masonry buildings. Table C8A.2.1 (Circ. 617/2009, Italian Code) provides average values of mechanical characteristics for 11 masonry categories typical of existing structures. In certain cases, they are not sufficient to cover specific masonry types individuated in regional context. In this paper, the results of experimental tests performed on particular masonry panels “out-of-Code” taken from bearing walls realized with hollow brick blocks or hand-made concrete blocks, are shown. The main qualitative characteristics of these two masonry types are identified through the filling out of a Masonry Quality Form, in which the features of the walls’ weaving and cross section are illustrated. The analysis of the experimental tests’ results, accompanied by a careful qualitative description of the masonry panels, is a preliminary step for the integration of the masonry categories of the Italian structural Code.
