Blades of wind farm structures should be designed to maximize the capacity generating lift force in the specific range of wind velocity. Although many studies related to wind farm efficiency have been performed but it is few to secure safety in the environment of high wind velocity. This study uses Computational Fluid Dynamics to analyze wind load on the blade and member force transferred to footing. And it is analyze wind load property variation related to the turbulence intensity because the wind property variation can be affected to generate the unstable motion on the blade, tower and footing. The maximum force loaded on the footing can be affected to the response of structure. The load variation by turbulence intensity can be considered when design the wind farm structures.
