Abstract: One of the important challenges facing the US today is the need for resilient networked infrastructure. The electric power delivery system is one of the critical lifelines that comprise the networked infrastructure. Power delivery systems have received a great deal of attention in recent years because most of the other lifelines such as telecommunications, transportation and water supply require power to function properly. In this paper, the resilience of power delivery systems is assessed for wind and seismic loadings using definitions derived by Bruneau (2003) and applied to in-situ post event data for extreme events.
