Progetto Antaeus: Una metodologia di valutazione della vulnerabilità dell’edilizia diffusa nella Provincia di Foggia

The subject of this paper is to propose a seismic vulnerability assessment method based on a simplified survey form. Presently, most part of the mid-scale seismic vulnerability studies in Italy are based on GNDT method proposed by Benedetti and Petrini in 1984 for masonry buildings. Although this method is widely accepted and validated, it requires the compilation of a detailed survey form for each building by a team of specialized engineers. For this reason, the method becomes time consuming and expensive for wide scale seismic vulnerability assessments. The purpose of this work is to propose a simplified form (the ANTAEUS form) that can be quickly compiled by non-specialized technicians with the use of pre-existing documents (plans or land registry files) and by performing a short visit of the building. An algorithm for the estimate of the vulnerability index is also provided, with the aim of matching the GNDT index. The methodology has then been applied for a seismic risk assessment study (the ANTAEUS project) concerning four historical centres of the Province of Foggia
