Seismic Vulnerability and Construction Types in Historical Buildings

This study is part of a research, aimed at the definition of a new expeditious method, in the pre-seismic phase, for the analysis and assessment of the seismic vulnerability of the historical urban centers. The typological-probabilistic approach adopted for a sample of buildings leads to qualitative assessments of vulnerability through the preparation of thematic maps and the adoption of Damage Probability Matrixes (from now on DPM). The paper reports the results obtained for the historical center of Ortigia.
