Seismic Vulnerability Evaluation of a Part of Water Distribution Network in District Number 22 of Tehran Metropolis

Tehran as the most important and populated city of Iran is located in one of the mostearthquake-prone zones of the country. Earthquake have repeatedly stricken this region duringthe previous centuries. The water network of this metropolis has been in operation for morethan 60 years. Based on the experiences gained in the past major earthquakes in world,vulnerability of water distribution networks has had a variety of important adverseconsequences in managing the disaster situations, also its interaction with other lifelinesfunction make the reconstruction process to slack. Tehran 22th region seismic function andVulnerability which has constructed as the Sample Urbanity in Iran, is too important. So thisPaper checks the seismic vulnerability of a part of this region water network with linear timehistory analysis applying Kobe, Northridge and Tabas Accelerograms to this part. Figure (1)presents the water network map of this region. Also the interaction effect of the broken pipesand joints water Leakage on traffic capacity of the main street, has been calculated. Figure (2)Presents the map of selected region streets.
