Large scale seismic risk assessment procedures require extensive knowledge about hazard, vulnerability and exposure.

Abstract
Large scale seismic risk assessment procedures require extensive knowledge about hazard, vulnerability and exposure. More specifically, acquiring detailed information on vulnerability may be arduous, given the high heterogeneity of the built environment. This aspect is particularly challenging in coutries like Italy, which are made of old and heterogeneous building stock. For this reason, it is convenient to derive vulnerability information from existing databases. A project funded by the Italian Civil Protection Department started collecting data on residential buildings in Italy since 2014. The so-called CARTIS form has been used for this purpose. The form, developed by the Italian Plinius Study Centre, is based on interviews with local experts or technicians and the collected data are stored in an online database accessible by the project members. These data can be employed for seismic vulnerability assessment purposes but, given the large amount of information, is difficult to manage without the support of automated tools. In this paper, a computational procedure interacting with the CARTIS database to derive building portfolios at the large scales is presented. The procedure is applicable to both unreinforced masonry and reinforced concrete buildings. Steps of the procedure are described, highlighting the challenges and assumptions made. A case study application in Central Italy is presented to show the potentiality of the procedure. The proposed procedure is implemented in a script that is freely downloadable, and Users are encouraged to contribute to its development.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
