Abstract
Recent seismic events are a unique opportunity to monitor and collect detailsof direct repair costs and the downtimes associated with massive reconstructionprocesses. This paper focuses on the actual repair costs of five RC buildingsdamaged by the 2009 L’Aquila earthquake. The repair costs for structural andnon-structural components that experienced different types of earthquake damageare discussed and then used as a benchmark for the predictions. The comparisonat both the building and component levels revealed that the FEMA P-58methodology is suitable, in general, for application to different types of buildingstock. Ad-hoc upgrades to the FEMA fragility database for components that aretypical of the Mediterranean area are required. When implementing the proposedmodifications, a reasonable level of consistency is achieved in terms of actual andpredicted repair costs (differences in the range of 30-48%). A discussion on theactual repair costs and the main differences with the predicted costs for infills andpartitions, structural sub-assemblies, floor finishes and other accelerationsensitivenon-structural components is provided along with suggestions for furtherimproving.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
