SEISMIC RELIABILITY ANALYSIS OF LARGE SCALE LIFELINE NETWORKS

抄録（英）：
An efficient procedure for assessing the seismic reliability of lifeline networks has been developed using the concept of the critical distance to a fault, the shortest distance to the fault that causes failure of components for a given earthquake magnitude. Lifeline components are assumed to fail because of ground shaking. The seismic environment of a lifeline is defined by the fault rupture model through the relation between the seismic moment and the rupture area. The enumeration of paths in the network was found to be at most 2■-2n+2 for a network with n components. Computation of the seismic reliability of an example network shows that this new technique is feasible for use with large networks.
