Abstract
A method for detecting changes in a building structure of a first wind turbine is provided. A reference value representing the eigenfrequency of the first wind turbine is monitored over time, whereby substantial changes in the reference value are used as an indication of changes in the building structure. Further, a detection assembly for such detections is provided.
