The inelastic behavior of structures is not a choice of seismic design today, but it is an inevitable fact that they are unable to control in large earthquakes. I can control the behavior of the structure because I introduce into the structure an external force coming from the ground (without the presence of a mass that increases the intensities) in response to seismic shifts. I deflect all the axial forces that develop on the wall into the ground, while today they send them on the cross-sections of the beams and after being deformed excessively, they fail. Another very serious thing is that I control the bending, increase the ability to receive the cutting at the base by 50% and improve the foundation ground. I also eliminate the shear failure of the concrete that appears on the concrete and steel interface due to the tensile strength of the steel which turns the failure into a shear shape that is extremely brittle, and is the result of the concrete cooperation mechanism with the relevance.

I agree with Dr Ioannis . It is an excellent idea. Thank you Dr Ioannis.
I guess the model structure you used in your YouTube video is made with non-reinforced concrete? Can I ask what was the purpose of the test? I am sorry it was in Greek, and hence could not understand the accompanying text with the video.
Dear Messaoud Saïdani
It is made of reinforced concrete under scale. 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%.
Thank you Ioannis for the explanations and the details. It is really impressive, and quite important research especially in countries like Greece that are prone to earthquakes. I wish all the best with your research and hope to read your publications of the findings.
