This work focuses on the definition of vulnerability for Italian residential masonry buildings. Fragility curves are elaborated for a database of 445 buildings through the software Vulnus 4.0, both for the as-built configuration and different intervention solutions. These vulnerability models are then combined with hazard and exposure data within the IRMA platform (Italian Risk MAps) to elaborate seismic risk maps for Italy, which show the possible losses for different return periods and time windows. By comparing the results provided by IRMA for the as-built configuration and the retrofit cases, it is possible to quantify the effectiveness of different mitigation strategies in terms of vulnerability reduction. © 2022 The Authors.

Abstract The seismic events that struck Italy in the last decades have highlighted the high seismic vulnerability of the built heritage. It is therefore of utmost impor an e to plan and prioritize mitig tion strategi s that can eff ctively reduce the amount of economic losse and the number f casual ies pr duced by earthquakes.
