Part of: Seismic Evaluation of Lifeline Systems—Case Studies


Probabilistic risk analysis methods are applied to the evaluation of seismic and non-seismic vulnerability of a 25-kilometer length of a major lifeline aqueduct system. In addition to considering the current aqueduct configuration, a number of hypothetical or 'modified' configurations are modelled as a means of further quantifying the components of system risk. The risk methodology employed shows clearly the relative importance of the various sources of hazard exposure studied, and provides powerful insight into a complex engineering problem with many system components, system configurations, and potential failure modes.
