     this paper investigates the seismic behavior of wind turbines including soil-structure interaction (ssi). because of high risk of earthquake in iran and the effects of soil condition in seismic analysis, one of the most important issues in design of wind turbines is seismic analysis of these structures including ssi. in this study a model for seismic analysis of wind turbines including ssi is introduced. ssi can be considered by rigorous or approximate methods. rigorous methods require considerable amount of expertise in idealizing the dynamic system and significant data preparation and interpretation of the results and also are not economical. instead the approximate methods can save time and expenses by representing a more practical model for ssi, although these procedures have approximations that cause deviations smaller than the typical engineering accuracy. for the present study ssi effects is considered using cone models that is an approximate procedure. wind turbine is modeled in fe based program opensees with beam-column elements. results show that ssi can affect the responses and should be considered in seismic analysis of wind turbines to have more trustworthy outputs.
