The present invention relates to a system comprising of motion-damping sandwich elements and energy-absorbing steel mandrels arranged between the building foundation and the superstructure, where at least a certain part of the sections receiving the steel mandrels in the building foundation is formed as a sliding block movable in the horizontal direction and embedded with expansion gaps in all directions in relation to the foundation. These blocks are placed onto sliding layers of low friction coefficient. During the earthquake, the fixed spring elements will be deformed. As soon as the deformation reaches a fixed limit value, the spring elements embedded with the lowest expansion gap step in and increase the rigidity. The stepping in of the further springs can be controlled by selection of the expansion gaps.

Progressive shock absorption system for reducing the seismic load of

Cables are provided between the foundation and the superstructure and arranged in the vertical cavities of the foundation and the superstructure and, both of their ends are provided with head pieces wider than the diameter of the cavities and elastic padding or padding elements are installed in the upper head piece. The diameter of the cavities in the foundation is increasing upwards, while in the superstructure it is increasing downwards. The elastic padding elements may be rubber and/or neoprene discs and are arranged along the upper enlarged section of the cavities in the superstructure.
