Abstract
In this study, it is investigated how the seismic damage of lifeline systems interacts on each other during and after severe earthquake. For this purpose, items associated with seismic damage are carefully extracted on the basis of past earthquake damage data. Then, by appling both the interpretive structural modeling method and the fuzzy structural modeling method on these items, a seismic damage influence model is constructed in the form of an oriented graph, whereby the mutual relationship among lifeline damages are evaluated qualitatively.
