Consideration of multiple hazards and climate change in time-dependent resilience assessment
Year: 2025
Type: conference-paper
Abstract: Civil structures and infrastructure systems are expected to be resilient during their service lives, i.e., they have the ability to be in readiness for, to absorb, recover from and adapt to disruptive events.This is particularly the case when considering the potential impacts of climate change, which may lead to non-stationary natural hazards in the future.Moreover, the presence of concurrent multiple hazards may result in more severe performance reduction to structures/infrastructures, compared with the occurrence of single hazards.In this paper, we will discuss the time-dependent resilience assessment of structures and infrastructure systems exposed to the impacts of concurrent multiple hazards in a changing climate.The interaction between different types of hazards is reflected through the mutual dependency between the performance functions associated with these hazards.We will also address the relationship between the time-dependent resilience and the performance concern index (PCI).Finally, an example is presented to demonstrate the assessment method for time-dependent resilience.
