Abstract
Lifeline systems such as transportation and utility networks consist of numerous structural
components which are spatially distributed and mutually interdependent. The damage to a
particular system caused by natural or man-made hazards is propagated to other systems
and results in additional losses due to cascading failures. Therefore, understanding the
influence of hazards on these interdependent systems is critical to mitigate damage and to
perform effective response and recovery efforts. This report focuses on modeling the
interdependency between lifeline systems and investigates the effect of such
interdependency on the seismic performance of these systems. A probabilistic model is
developed to characterize the interdependencies and integrated into a simulation model for
estimating the seismic performance of the system. Example analyses show the effect of
various levels of interdependency on the performance and demonstrate the importance of
considering such interdependencies.
