Experimental characterization of “non-engineered” masonry systems in a highly seismic prone area

In a context where it would be very difficult to directly obtain the required experimental information, the objective is to improve the knowledge about local materials and their mechanical features, providing at the same time a reference methodological approach. In the absence of appropriate information (i.e., of a low level of knowledge) the safety verification and vulnerability assessment turn out to be very conservative. It is thence nearly impossible to provide an effective strategy for the rehabilitation/retrofitting against seismic risk, whereas the systematic, complete substitution of the existing residential housing would became the only solution, which is nowadays a non sustainable option.
