Vulnerability of Architectural Heritage in Seismic Areas: Constructive Aspects and Effect of Interventions

In this chapter, the effects of past interventions applied to historical city centers struck by a series of earthquakes over time are analyzed in terms of local and overall damage. Three villages in central Italy, Castelluccio di Norcia, Campi Alto di Norcia and Castelsantangelo sul Nera, containing overall about 150 buildings, are examined here. Classification of damage was based on the European Macroseismic Scale. The study provided vulnerability maps detailing the influence of interventions on buildings in historical city centers, which may contribute to better evaluation of damage scenario and maintenance plans.
