Applicazione della metodologia “Antaeus” per la stima della vulnerabilità di livello 1 nella Provincia di Foggia.

The purpose of this paper is the validation and application of the vulnerability assessment method based on a simplified survey form for the evaluation of the seismic vulnerability index for masonry and RC buildings: the “ANTAEUS” form. The form has been used for the survey of 4560 buildings in the municipalities of Foggia, Carlantino, Vico del Gargano and Sant'Agata di Puglia. For each one, a sample of the buildings has been extracted and then used for the calculation of the index of vulnerability with the GNDT method, with the purpose of validating the ANTAEUS algorithm. On the basis of these results, a calibration of the parameters involved has been made, introducing some improvements in the form and in the algorithm, with the aim of best matching the GNDT index. Finally, the collected data have been implemented within a GIS software and used to draw a number of significant thematic maps about the vulnerability parameters and the final vulnerability indexe for the four historical towns.
