These scientists who are doing this experiment.

They know how to protect the seismic base from the fall of the experiment by placing iron protection scaffolding around the experiment, but they don't have the imagination to realize that this scaffolding can 100% protect the houses from the earthquake.
Instead of making structures with protective shafts and walls they make rocking walls
My proposal for seismic protection in the video.

1. This video design method involves a flexible structure with columns, and within or outside this flexible structure we place a lift shaft, or one or more independent rigid shear walls of reinforced concrete, with appropriately shaped plan sections and with prestressed ends connected to the ground. No large foundations or connecting beams are needed since the moments are taken up by the ground.
2. Independent columns and independent rigid walls mean that they all take their respective seismic loads.
3. We place horizontal seismic insulation at the base to prevent high accelerations.
4. We install strong damping tires to ensure smooth absorption of the impact between the diaphragms of the plates and the walls. This gap between two or more independent structures is increased in height per floor to ensure smooth natural oscillation, because if the gaps were the same, moments would be diverted to the base.
The difference in displacement and impact phase results from many factors of elasticity stiffness and height.
In this method, the displacements of the two independent structures cancel each other out due to the inter-impact and the inelastic deformation of the elastic structure with supports is prevented by the stiff shaft.
5. At their upper ends, the walls have hydraulic jacks connected to the prestressing tendons. When rigid elevator shafts tend to overturn due to displacement, the fluids in the hydraulic jacks heat up because they prevent deformation, converting the kinetic displacement force into heat, creating a smooth elastic seismic damping.
6. The deflection of seismic forces to the ground and the high stiffness of the walls and the bearing capacity of the foundation soil is given and is due to the pre-stressing and connection of the ends of the walls to the ground.
7. This design allows for plenty of light and great visibility.
Dear Samy Elhadi Oussadou
Correct They cannot understand that the protection offered to the seismic base by scaffolding embedded in the seismic base could be the solution to controlling inelastic displacements.
As I did in the video. https://www.youtube.com/watch?v=IO6MxxH0lMU
I will add another innovation to the video
The impact between the two independent bodies in the experiment on damping tires, mutually canceling the displacements
