Task Group 1.8
Design Requirements for Infrastructure Resilience
Over the last decade, the concept of the resilience of cities, infrastructure and societies has emerged aimed at achieving the stated goal as well as ensuring recovery to a normal operational state in a relatively rapid and cost-effective way, i.e. resilience.
Several definitions of resilience were suggested, and various frameworks and tools for resilience assessment have been developed or built upon the existing models.
A wide variety of modules is available, including identification of likely failures and performance of structural and infrastructure systems, recovery of loss of functionality and preparation of recovery plans for disaster events, among others. Thus, resilience assessment tools are becoming more sophisticated, aiming to assist engineers, infrastructure operators and owners, decision-makers, and planners to perform a resilience-based design and/or assessment of individual buildings, critical infrastructure, and cities, and in this way to efficiently manage assets, reduce maintenance costs, as well as withstand and recover from catastrophic events.
In this Technical Group, we start by a review of on-market available definitions, methods, and tools and discuss its developments and then identify limitations and future needs, including the use of monitoring systems for enhancing infrastructure resilience. A second, step would be to propose a unified framework, toward well-informed quantitative risk and resilience designs and assessments of infrastructure, and to propose a recommendation for a framework that encompasses other stakeholders.
