Aerodynamic analysis of wind turbine tower is one of the most important in structual design of wind turbines. Usually, dynamic response of the wind turbine tower under aerodynamic forces is calculated using the finite element method. FEM has high accuracy but it can considerably increases the computational works depending on the modeling type of foundation and modeling axial force variations. In this paper, transfer matrix method is used to reduce computational works and increase the speed of analysis instead of the FEM. For this purpose, the wind turbine foundation is modeled using CS model and required relations are extracted to determine of wind turbine response.Then, the transfer matrix method obtained results are compared with the results of the analytical method and experimental data in several case study which show good agreement in spite of low computational cost.
