Wind turbine - rotational stifnness
Wind turbine - rotational stifnness
(OP)
Hello
I'm working on windturbine foundation.
There is one criteria that rotation stiffness ratio have to be more than 6*10^10 Nm/rad.
Do you know how to assume that value properly ?
Do you know any computational solution?
I have: demensions of foundation, ground conditions (mostly clay, sandy clay), loads on the buttom of foundation.
Thank for your help
Best Regard
TOM

I reckon that might turn out to be overconservative especially in soft soils, where damping phenomena are significant.
Also, that way if there is a strong acoustic impedence contrast, eventual multiple refraction and reflection phenomena are ignored, and this would result in an underconservative design.
Unless dynamic conditions are illustrated in other parts of the same publication.
