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.
An apparatus for anchoring a foot of a tall structure in the ground, said tall structure being subject to dynamic forces loading the tall structure with horizontally effective load components and with vertically downwardly effective load components, comprising a substantially rigid foundation, said foundation having side wall means and bottom wall means forming an opening for receiving said foot, said foundation side wall means forming a ring gap around said foot, said foundation bottom wall means being spaced from said foot to form a further gap, said apparatus further comprising elastic ring bearing means (11, 11') operatively interposed in said ring gap between sides of said foot and said foundation side wall means substantially near an upper edge of said foundation side wall means, said elastic ring bearing means comprising at least one elastic ring bearing element having a spring damper characteristic for holding said foot substantially against said horizontal load components and for damping vibrations of the tall structure, and pivot bearing means (10, 10') operatively interposed in said further gap between the bottom wall means of the foundation and said foot for taking up substantially only said vertically downwardly effective load components, said pivot bearing means being located at a given vertical spacing from said ring bearing means.
