    Abstract

    ![CDATA[Lifeline networks are fundamental to our quality of life, to economic growth, and to the environment, but their components are intensely vulnerable to natural and man-made hazards. To minimize these hazard effects and to prevent functional damage propagation, it is essential to prepare effective pre-disaster hazard mitigation strategies based on rapid system reliability assessment. In this paper, the Logical Expansion of Recursive Decomposition Algorithm (LE-RDA), a non-simulation-based network reliability analysis method, is utilized to efficiently estimate the reliability of lifeline networks whose failure is defined by the complex failures of multiple node pairs. LE-RDA is demonstrated by recent lifeline network examples to estimate the seismic performance, functional degradation, and interaction effect, all of which are defined by a complex mixture of events. A new convergence-based efficient framework for LE-RDA calculation is introduced as well. LE-RDA can be applied to the node pair connectivity analysis of any general lifeline networks for decision support in hazard mitigation planning and disaster prevention management.]]
