A community is comprised of a complex and dynamic system of infrastructure and networks. The infrastructure serves the human needs and in an extreme event, ideally this infrastructure remains operable; but most infrastructure are not designed to resist low probability – high consequence events. In addition, the functionality of infrastructure such as buildings and bridges are typically studied in isolation, meaning it does not consider how they interact with – and depend on – networks such as water, power, and transportation. This new line of research examines the functionality of buildings following an extreme event considering the interdependencies of various networks as well as building structural response. In particular a fire following earthquake scenario is evaluated for an urban community. As a first step, we have developed a probabilistic fire ignition model based on historical data that can be implemented in an open source GIS-based software (Ergo/Maevis). In addition, fire fragility functions are being developed for a suite of building typologies.
