Abstract: In this present paper, selected results concerning the static strength behavior of a three-dimensional (3-D) steel tower for a 850 kW horizontal-axis wind turbine are presented. The tower structure is 55 m height and consists of thin-wall cylindrical and three conical sections with variable wall thicknesses and variable cross-section axially along its height. The static response of the structure was investigated under gravity loads (nacelle, rotor and tower), rotor force and extreme wind loads with the aid of finite element (FE) software SOLIDWORKS Simulation. Based on simulation results, the tower structure satisfy the design requirements of static strength according to maximum von Mises stresses, maximum displacements, strains and minumim factors of safety.
