Abstract
The importance of non-stationarity in loads and resistances of geo-infrastructure is pointed out in this paper. Temporal variations of loads and resistances are now becoming an inherent aspect of civil infrastructure systems, particularly because of the effect of climate change. Non-stationarity of loads and resistances affects the sustainability and resilience of geo-systems and, if not taken into account properly, may lead to unsustainable outcomes. Inherent in the concept of resilience is the aspect of temporal variation, and therefore time-dependent reliability estimation of a system can be related to its resilience. An example of time-dependent reliability calculation for an offshore wind turbine (OWT) foundation is presented. How such calculations can be related to the resilience and sustainability of OWTs is conceptually outlined.
