Damages caused by possible earthquake scenarios are predicted by earthquake engineers. To determine the performance of water distribution systems after an earthquake scenario, there is a need for network reliability analysis. While performing earthquake hazard analysis, defining the seismic vulnerability model, and estimating the probability of pipeline failure, the study discusses the effects of various earthquake scenarios on pipeline reliability. The innovation of the study is the inclusion of the results of the Probabilistic Seismic Hazard Analysis (PSHA) in the reliability analysis and the investigation of the seismic performance of the pipelines according to various probabilistic methods. The results emphasize the use of Monte Carlo method in estimating the reliability of lifelines, and the need to consider two or more focal earthquakes in estimating the vulnerability of water distribution systems.
