Analysis of Steel Tubular Wind Turbine Tower with Door Opening

With increasing demand of sustainable energy, the production of wind power by using wind turbines have become increasingly important over the last few decades. The tower is provided with a door for the inspection and maintenance of the equipments inside the tower. The main objective of this paper is to investigate the stresses around the door opening of wind tower for the load case and to find out the best stiffener. The loading of the tower generates the stresses around the door opening and these stresses will analyze for static analysis using the FEM software ANSYS R15 as there is more probability of having crack near the door opening. Analysis of the opening with stiffeners are also carried out. For analysis wind load is considered along the side of the opening.
