Abstract

A methodology to simulate the seismic damage of non-reinforced masonry buildings ex- isting in a urban zone is presented. The methodology is based on the Italian vulnerability index and on the results of a post-earthquake damage survey study. The Monte Carlo Method has been then used to simulate damage probability matrices and vulnerability functions, which are the basis of any seismic risk study. The simulation process required the generation of thousands of hypothetical buildings, the analysis of their seismic be- haviour and probabilistic studies of the computed results. As an example, probable damage scenarios have been developped for an urban zone of Barcelona. 1 Introduction The damage produced by earthquakes in structures has stimulated stud- ies on seismic risk in general and particularly related to old buildings, for which a high damage degree may be
