AbstractThere are two specific objectives in this research The first one is developingprobabilistic models for buried pipes in prevalent seismic loading In fact such modelsmake suitable tools to estimate losses in lifelines Parameters like corrosion size ofpipe ground settlement are directly involved in suggested procedure From thisview point developed models have advantages over previous models The secondobjective is suggesting different procedure for prediction of the loss in a city gasnetwork associated with a certain earthquake In a gas network poles are vulnerabletoo Damages in these members depend mostly on the extent of collapse of adjacentbuildings so a method is suggested to estimate the collapse probability of building asan appendix to this thesis Initiation spreading of fire following earthquake areassessed by studying physical models Stop in gas delivery is considered as anothersource of loss in a gas network To calculate this kind of loss the network is modeledas a combination of feeding nodes and consumption regions Finally the mean of totalloss is suggested as a function of elapsed time after earthquake Describing lossfunction in this way makes it possible to compare the city regions taking in to accountvarious loss sources As an another application the time dependent loss function conalso be used to calculate the effective time for preventive measures For drivingeconomical loss estimation it will be necessary to have realistic values for theparameters involved
