After recent seismic events, many information are made available about the seismic vulnerability of existing buildings. In particular, the data collected through the AeDES forms by the Italian Civil Protection provided information about recorded damages on thousands of buildings, with different structural typologies, construction materials and geometric properties.

Abstract
After recent seismic events, many information are made available about the seismic vulnerability of existing buildings. In particular, the data collected through the AeDES forms by the Italian Civil Protection provided information about recorded damages on thousands of buildings, with different structural typologies, construction materials and geometric properties. At the same time, the large extension of Italian accelerometric network allows us to estimate as well the recorded ground motions intensity measures with moderate approximation. In this work, a preliminary elaboration of the data available for the L’Aquila earthquake (2009) is presented, in order to provide fragility curves of the expected seismic damage and the loss curve estimating the reconstruction cost percentage. The data examined are available on Da.D.O. web-gis database and the preliminary results discussed in this paper regards the typology of old ordinary masonry buildings.File | Dimensione | Formato | |
