The individual foundations of the structures have been completely removed
The walls must be connected with foot girders which, mainly, try to receive the overturning torque.
That is, we do not rely on individual foundations to receive torque.
Much more ... when there are multi-storey constructions, there are always the corresponding floors of the Underground, which "anchor" the reinforcement of the wall.
It has been proven that buildings with Underground floors are much stronger in the earthquake because there is better anchoring of the superstructure reinforcement inside the basement walls, and because the walls of the Underground floors are strong in torques.
Foot girders in large earthquakes, try unsuccessfully to pick up these huge torques that lower the walls of smaller buildings, and are usually unable to pick them up.
But as much as it seems that the anchoring of the wall reinforcement inside the Underground floors is the same with my own design proposal, they are different.
I do not suggest just a simple anchoring to the ground.
I suggest compression on the sides of the walls combined with anchoring in the ground.
Where are the differences between the anchoring inside the walls of the Underground floors, and the pre-tensioning + anchoring to the ground.
1) We insulate the Underground floors externally, then we rub them around the perimeter.
Due to the looseness of the rubble, their reaction to the torque of the whole structure is small.
But they resist with their own weight and this is a positive reaction to the moments.
If the Underground floors have the same mass as the mass of the upper structure, then yes we have anchoring.
But this is not possible.
Usually the floors are much more than the Underground floors and this means that the Underground floors in large earthquakes have a tendency to overturn, but small.
Beware .. I'm not talking about a complete overturning of the building, but a small overturn of the total area of the base of the Underground floors.
This means that the building loses some ground support.
This is equivalent to creating a corresponding torque from the unsupported static loads, which contrasts with the torque of the building.
These two opposing torques create cross-sectional failures.
This does not happen with the full anchor with my mechanism
2) The prestressing that I propose on the sides of the walls ensures less deformation by bending, zeroes the tensile strength in the cross section, at which point the shear failure of the coating concrete due to the high tensile strength of the steel and its low tensile strength. It ensures that after leaks the construction will return to its original position, so the pre-tension is considered elastic functionality.
It also provides resistance to the shear of the base. Anchoring + prestressing ensures the neutralization of moments (M), upright forces (N) (compressive and tensile), and shear (Q) and deflects inertia tensions into the ground by preventing displacements that deform and break cross-sections around them. nodes.
