PURPOSE: A structure of a wall cross-section of a wind turbine tower is provided to reduce the weight of a large wind turbine tower, thereby obtaining high economic efficiency and improve the rigidity and ductility. CONSTITUTION: A structure of a wall cross-section of a wind turbine tower comprises a concrete unit(12), a hollow unit(14), and an inner pipe unit(13). The concrete unit becomes tapered from a lower part to an upper part. One or more hollow units are formed inside the concrete unit. The inner pipe unit is attached to the inner periphery of the hollow unit. |
