ABSTRACT:
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.
