Seismic resilience: concept, metrics and integration with other hazards
Resilience is a new approach in earthquake engineering that introduces the time dimension to cover the post-event recovery phase. It also broadens the scope beyond the single structure, to systems and communities. In the wider sense, resilience incorporates technical, organization, social, economic and environmental issues. The current goal of minimising casualties, economic and functionality loss, is extended to the requirement for the affected community or system to return to ‘normal’ conditions within the shortest possible time.
This report covers both conceptual and operational aspects of seismic resilience. It presents mathematical expressions used for the quantification of resilience, together with single- and multi-dimensional functionality measures for assets and systems. Moreover, it deals with interdependencies between systems, uncertainties, and multiple hazards and events.
In view of the establishment of a common methodology for resilience assessment, topics that need to be further investigated include the definition of boundaries in relation to space, time and the aspects to consider in resilience assessment, the collection and dissemination of data, the calibration of recovery functions on existing data and the validation of methods through application to real-life complex systems.
