Abstract
Wind power generation has been spread worldwide even in Japan. However, it has been reported damage collapse accident of windmill wind power generation facilities in Japan, and it has become a major problem. In the development of wind power installation, wind conditions in Japan are seriously problem for wind gust and typhoon effect and so on. In addition, overturning and torsional moment effects for wind turbine tower structure are very important for collapse trigger. In this study, moment and load for wind turbine structure were examined for changes in overturning moment and torsional moment in simulated natural wind. In considering the similarity law, it was revealed for generalized moment and load characteristics.
