Damage scenario-based approach and retrofitting strategies for seismic risk mitigation: an application to the historical Centre of Sant’Antimo (Italy)
In this framework, the current research work aims to analyse a sub-urban sector of the historic centre of Sant'Antimo, located in the province of Naples (Italy), in order to assess the seismic vulnerability of old masonry buildings in this sector and the expected damage scenarios resulting from seismic events with different characteristics. Moreover, in order to mitigate the identified risk, a set of retrofitting techniques are considered and analysed taking into account their contribution for the reduction of the seismic vulnerability of buildings. The vulnerability analysis is performed through the application of an index-based seismic vulnerability assessment approach integrated into a GIS tool in order to identify the structural units (S.U.) most susceptible at damage. Subsequently, typological vulnerability curves, according to the EMS-98 scale, are obtained for the building stock analysed. Finally, a parametric analysis, varying magnitude and seismogenic site-source distance, is performed to obtain and discuss urban damage and loss estimation scenarios in terms of number of collapsed and unusable buildings, as well as number of human casualties, severe injuries and homelessness.
