The wind turbines are used to convert the wind energy into electrical power. Wind turbines are mounted at the top of the vertical structure called Wind Tower. Increasing demand of high power generation in is compelling the towers to be made taller, so as to catch strong winds at higher altitudes. It focuses on designing a tower for Uttara Kannada, the Western Ghats of Karnataka State, which is one of the potential source of wind energy. It begins with understanding of the physics involved, in their function. Analyses of the stress and strain behaviour of the welded fixture have been done at bolted ring flange connections under different loading conditions. The maximum stress and fatigue life were estimated, using the Finite Element Analysis (FEA). Processing is done using ANSYS WorkbenchV14.5. Also various checks have been performed to validate the results. Optimization of thickness of wind tower shell and number of bolts for the specific joints were done with the objective of minimising structural weight and cost as well. The optimum number of bolts found suitable for middle flange and for top flange joints were 100 and 80. Keywords— Wind Tower, Design, FEA, Fatigue Life.
