Vulnerability analyses in a sample of 18 municipalities in the Veneto-Friuli area (NE Italy)

Preliminary classifications of the number of buildings and their volumes in every census section based on “poor” data obtained from national statistics (ISTAT91), are verified through a first-level survey form (AeDES) with a sample of 18 municipalities selected so as to represent the residential building types in the total area of interest in the provinces of Belluno, Treviso and Pordenone (NE Italy). Criteria in the selection of the sample of municipalities and in every municipality of a representative sample of census sections are discussed. The numerical results allow us to evaluate the actual vulnerability, depending on the local historical developments of building types and moreover, on the criteria used in the past century for seismic classification of their territories.
