Fatigue of anchors for the fastening of wind turbines to reinforced concrete foundations. Vermoeiing van ankers voor de bevestiging van windmolens aan fundaties van gewapend beton

Abstract

Nowadays slender and slack masts are preferred for wind turbines, fastened to a concrete foundation with anchor bolts. This concept leads to strongly fluctuating forces. Tests are described to investigate this aspect of wind turbine design. Test specimens were designed and loaded in such a way that the real situation was simulated as close as possible. They were subjected to fatigue tests and duration tests. Some important conclusions are: foot plates with two contact surfaces are significantly better than those with only one contact surface; a good filling of the seam, especially in a direct line with the mast is essential.
