Abstract

The present research aims to investigate the influence of site amplification on the seismic vulnerability of the historical centre of the municipality of Baranello in the Molise Region of Italy. Structural and typological characterization of the investigated area has been done according to the EMS-98 scale. The vulnerability assessment of the historical buildings located there has been carried out through an appropriate survey form in order to identify the buildings most susceptible at seismic damage. Furthermore, according to the AeDES form implemented by the Italian Civil Protection Department, the calibration of the typological vulnerability curves of the built-up area has been done based on the seismic motions recorded after the 2002 Molise earthquake. Finally, the local amplification factor, which negatively influences the severity of the seismic damage on the structures, has been taken into account according to the time-domain method. To this purpose, a refined and simplified approach to foresee the expected damage of the inspected urban sector has been proposed, so to use more appropriately the achieved results for reliable seismic risk mitigation plans.
