Abstract

ABSTRACT: A buildings stock of 12, 016 Reinforced Concrete (RC) buildings is investigated to propose vulnerability, fragility, and loss curves, as well as an Expected Annual Loss (EAL) assessment. The buildings data are collected within Da.D.O. database, considering the observed damage due to L'Aquila earthquake (2009). The adopted methodology allows us to add undamaged and not-surveyed buildings, not included within the database, by considering the typological distribution of two different reference municipalities. The obtained results highlight that the completed database allows a more reliable seismic risk assessment, even if resulting EAL is poorly influenced by reference municipality assumed for undamaged buildings estimation.
