The storage sphere is supported by eleven steel columns welded around the envelope of the structure. The columns are interconnected by a bolted circumferential ring. Braces ensure increased horizontal stability of the storage sphere in cases of wind and seismic loads.

A 3D model was created in the structural engineering software RFEM. All components were entered as surface elements (spherical envelope, columns, circumferential ring, braces, gusset plates, anchor plates, and other components). The soil-structure interaction was taken into account using elastic supports, transferring the stiffness of the deep foundations in each spatial direction.
