A method is proposed for calculating the temporal variation of wind speeds during a typhoon to estimate wind load effects on energy-consuming structural devices and cumulative fatigue damage under an extreme typhoon event. This method is based on the concept of scenario-based design wind speed. It utilizes parameter scaling, and consists of selecting a seed typhoon that has affected the target site, identifying its parameters, modifying them and calculating the temporal change of wind speeds of a virtual typhoon. Some calculation examples are shown. The calculated temporal wind speeds give the same wind speeds as the design wind speeds and realistic temporal variations based on meteorological considerations. |
