| Research Abstract |
Interaction on a physical induced failure of lifeline networks is evaluated in views of a seismic hazard. We select electric power supply systems, gas supply systems, and water supply systems distributed in Tokyo metropolitan area for analysis, and these related facilities and structural components are modeled as network nodes and links taking into account their functional interaction. To reveal the trend of network system reliability and analyze its variation, numerical simulation by using network parameters of average degree 〈k〉, characteristic path length L, clustering coefficient C, relative size of the largest cluster S, average size of the isolated clusters 〈s〉 and accessibility ratio R_a, is carried out for the cases that the nodes exposed to a high seismic hazard are affected in entire interactive lifeline networks.
