  7. Abstract:
  8. The Reliability of substation structures with consideration of earthquake uncertainties is one of the most important subjects in structural analysis in recent years. In this project we first introduce IEEE-693-2005, which is the most effective and comprehensive seismic design code for electronic substations. Also in second chapter the rudimentary aspects of Reliability Theory and methods for evaluating the reliability of substation structures is introduced. Then with modeling the most common and most important electronic substation devices in Iran, with consideration of all seismic parameters and their uncertainties, the reliability of these structures evaluated. In this project for determination of Ultimate Limit Service (ULS) of structures we used push-over analysis. The evaluation of reliability of seismic design of substation structures is done with ISO methods. The results showed seismic design of electronic substations in Iran with consideration of IEEE-693-2005 is to some extent conservative in some fields and in some other parts non-conservative, therefore some correction in Load Factor( ) and Earthquake Resistance Factor ( ) should be considered. At the end Response Spectrum, corrected Load Factor and Earthquake Resistance Factor for seismic design of substation structures in Iran suggested.
