Firstly, fragility curves are illustrated and c mpared by consid ring the vulnerability classes of Da.D.O. (Class A, Class B and Class C1). Then, an approach is proposed in order to evaluate the total Expected Annual Loss (EAL tot ) and its contributions due to the several amage l vel (D 1 , …, D 5 ). The preliminary obtain d results show that, with reference to the two masonry buildings stock considered, th higher contribution to the (EAL tot ) is given by the dam ge level D 3 , that may be considered as the life safety limit state. In the case analyzed, the corresponding EAL D3 results almost equal to 1/3 of EAL tot . © 2022 The Authors. Published by ELSEVIER B.V.

XIX ANIDIS Conference, Seismic Engineering in Italy Seismic risk analysis on masonry buildings damaged by L’Aquila 2009 and Emilia 2012 earthquakes M. Tatangelo a *, L. Audisio a , M. D’Amato b , R. Gigliotti a a DISG, Dept. of Structural and Geotechnics Engineering, Sapienza University of Rome, Via Eudossiana 18, 00184 Rome, Italy b DiCEM, Dept. Of European and Mediterranean Cultures: Architecture, Environment and Cultural Heritage, University of Basilicata, Via Lanera, 75100 Matera, Italy Abstract Earthquakes in the recent past continue to provide more and more information on the seismic behavior of existing buildings and on the related economic losses. For the reason it is interesting to compare the damage of buildings stocks archived after earthquakes survey activities. In this paper a study of the damage occurred on masonry buildings after L’Aquila 2009 and Emilia 2012 earthquakes is carried out, by considering the data available in the web-gis Da.D.O platform.
