ANTAEUS Project for the Regional Vulnerability Assessment of the Current Building Stock in Historical Centers

This paper presents a methodology for the seismic vulnerability assessment of current buildings, suitable for the study of historical centres at the regional scale. The applicability is demonstrated with reference to four case studies: the historical centre of the city of Foggia (Italy) and three other small towns of this province, for a total of 4519 housing units. Field data were collected by several teams of technicians by means of a survey form, provided in electronic format. The subsequent data processing and drawing of vulnerability maps was performed using GIS. The collected data were used also for the validation of the algorithm, by comparing the results with those of the GNDT methodology, which is widely adopted in Italy. The results of the research study and the application showed some critical points, related to the poor nature of the information collected and to the reliability of the final results. These issues are analysed and discussed, proposing a strategy for improving the methodology.
