Seismic and energy retrofitting of residential buildings: a simulation-based approach

Abstract

The topic of the high seismic vulnerability of housing stock in Italy is back again at the center of political, economic, social and scientific-technical debate following the seismic crisis that struck Marche, Umbria and Lazio regions in 2016. These events have once again raised the need for a massive retrofitting program at National and Regional level, addressing the majority of the existing building stock, realized for 60% prior to the adoption of the first seismic code (Law 64/74), in a territory characterized north to south by high levels of seismic hazard. In recent years, different kinds of tools have been implemented to allow the simulation of natural hazards’ impacts on the built environment and to support strategic choices both in the field of emergency management and resilience-based urban design and planning. Nevertheless, an integrated set of instruments for a quantitatively informed decision support is still missing. Within EU-FP7 CRISMA project, an integrated DSS (Decision Support System) application has been developed, with a set of tools and functionalities addressing the main aspects involved in the decision-making processes for natural hazards preparedness and response
