Abstract
This apparatus relates to anchoring self-supporting tall structures such as asts, towers or the like in a foundation. The structure (2) is supported in the foundation (5) at its lower end on a pivot bearing (10). The weight of the tower is borne on this bearing. The structure is furthermore elastically clamped to the wall of the foundation at a location above the pivot bearing by elastic clamping device (11) operatively interposed between the wall of the foundation (5) and the sides of the tower. The clamping device generally comprises spring damper elements for damping and suppressing vibrations. The spacing between the pivot bearing and the elastic clamping device, and the characteristics of the elastic damping material are selected to lower and suppress resonance frequencies in the structure.
