Description:
The goal of our research has been to estimate the economic impact of the seismic hazard studies on the reconstruction phase after the 2002 Molise earthquake.
The study has been carried out adopting the vulnerability model, connected to the GNDT II level form, on a sample of existing masonry buildings of Campobasso province. A procedure has been provided to recover the necessary parameters for the vulnerability evaluation, using the AeDES 05/2000 forms, which are the basic support for the safety assessment in the post-earthquake phases.
Assuming a set of structural seismic upgrading intervantions, a correlation between the cost of ret-rofitting interventions and different limit state has been evaluated, taking into account the litologi-cal site characteristics, according to the recent studies of seismic microzonation of the earthquake epicentral area.
The results show a substantial difference of the seismic upgrading costs, varying the hazard (PGA) and the litological site characteristics, particularly in the 1st and 2nd Zones of the Italian Seismic Classification (OPCM 3519/06).
These considerations put in evidence once again the necessity to invest important economic re-sources in the building national heritage knowledge and in the seismic microzonation of the urban areas; only in this way an effective preventive planning of risk reduction can be perfomed.
