- Description
- According to the most recent IPCC report, warming of the climate system is unequivocal, and this warming may lead to increased risk of breakdown of infrastructure networks due to extreme weather. A key means of reducing future risk exposure is implementation of effective climate change adaptation strategies for critical infrastructure assets. This however constitutes a significant engineering challenge, for a variety of reasons discussed herein. The work described in this paper examines the regional variability of climate change adaptation feasibility for timber power pole networks, an important critical infrastructure asset. This is achieved through development of a Monte-Carlo event-based sequential model, which incorporates structural reliability, deterioration, climactic effects and network maintenance. The hazards of interest are storm winds and timber decay - both of which may worsen due to a changing climate. A probabilistic life-cycle cost-benefit analysis is used to examine the appropriateness of a single climate adaptation strategy for three Australian cities; Sydney, Melbourne and Canberra. Regional variability in power pole infrastructure performance is also compared across European and Australian networks.
