- Description
- This chapter discusses risk assessment of power distribution poles subjected to hurricane hazards and various mitigation strategies. Every year power outages due to wind storms cause an estimated $270 million in repair costs in the United States. Hurricane Irene left approximately 6 million residents without power along the east coast of the U.S. in 2011, causing an estimated $5 to $7 billion in damages. Risk assessment of power distribution poles is conducted considering various sources of uncertainties in the hurricane fragility, the effects of degradation of timber poles, and probabilistic wind models. Various hazard mitigation strategies are evaluated with a life-cycle cost analysis for their cost-effectiveness in reducing the vulnerability of poles due to hurricane winds. Certain mitigation strategies are found to have the potential to significantly reduce replacement costs due to hurricanes.
