Zusammenfassung:During the 2016 Kumamoto Earthquake, wind turbine generator support structures were damaged. Before repair of structures to restart, damage investigation was conducted including damage analysis. The damage mechanism and the characteristics of the damage according to each support structure was explained by the analysis. The analysis showed that the input ground motion level was estimated to be 1.0 time of that at the nearest observation point.
