Experiments
1) If we place a two-storey (under scale) building with corner walls and a bed base on the ground and shake it hard it will have the reaction shown in the video.

2) If we place a two-storey (under scale) building entirely of concrete and with a bed base on the ground and shake it hard it will have the reaction shown in the video.

3) If we place a two-storey (under scale) building with corner walls and with a bed base on the ground and screw the bed base with the ground and shake it hard, it will have the reaction shown in the video.

4) If we place a two-story (under scaled) building with corner walls and a bed base on the ground and screw the ends of the walls to the ground and shake it hard with the greatest seismic acceleration ever made in this world, it will have this reaction shown by the video.

5) If we place a two-storey (under scale) building made entirely of reinforced concrete and with a bed base on the ground and screw the ends of the walls to the ground and shake it vigorously, it will have the reaction shown in the video.

Question
Why do we just place the structures on the ground and not screw them on it?
With the method of designing, anchoring the nodes of the highest level with the ground, I hope to deflect the intensity of the earthquake in stronger areas than those areas that are driven today. These strong areas have the ability to absorb these intensities, preventing the relevant drifts and therefore the intensity that develops throughout the body is limited and return them to the ground where they came from, thus removing large tensions and failures over the load-bearing structure of the building while ensuring a stronger bearing capacity of the foundation ground. With the appropriate sizing design of the walls and their placement in appropriate places, we prevent the torsional baklin that appears in asymmetric and metal high-rise structures. General. The imposition of loads on the cross-sections of the walls by the nodes of the top level of the walls of a structure + their anchoring to the foundation ground, using the mechanism of the invention, deflects the stresses in the ground thus preventing the displacements of the control node and all the developing stresses on the trunk of the bearing elements caused by the inelastic bending deformations. The capacity of the walls to the cutting base is also increased by 50%.
