ƒ^ƒCƒgƒ‹i‰pjF Evaluation of post-earthquake functional performance of lifeline systems based on sequential update processing of damage information
´˜^i‰pjF In this study, the Monte Carlo filter was applied to identify post-earthquake maintenance of lifeline system. First the sequential update algorithm of damage estimation based on the actual damage information was proposed by defining probability characteristics of the Monte Carlo filter. Next the restoration process of the system with the progress of link repair was examined. Numerical results show that the damage information is updated using Bayesian approach in a sequential manner.
