The force of the earthquake shifts the construction back and forth creating torque on the walls.
The tipping torque is the opposite of the stability torque.
The tipping torque rotates the wall around the base joint.
In order to balance a wall from overturning, we must impose stability forces equal to or greater than the overturning torque.
A wall that extends in height from the base to the last slab on the roof, is a huge lever arm.
This wall has all the characteristics of a lever arm, such as multiplying and lowering high torques at the base, having a critical failure area, being subject to shear failure.
What I will tell you below is my research and is being applied for the first time worldwide.
1) I built a mechanism that joins all the ends, of the cross section of a wall, from the top level, together with the ground of the foundation, in order to create a moment of stability to balance the overturning torque of the wall.
The force that creates the moment of stability comes from an external factor, that of the foundation ground.
This means that this force does not come from the load-bearing structure of the building, so it does not have a mass that increases the inertia forces.
So we have the ability to increase the stability force indefinitely without increasing the inertia of the building.
The current state of science to balance the tipping moment of the wall uses the cross sections of the load-bearing elements which are joined together at nodes, to apply stability moments to the wall.
But when the earthquake is large and the acceleration of the ground is large, in conjunction with the height of the mass and the size of its weight, they increase the force of inertia and the moments of tipping, and the cross-sections break.
If we increase the cross sections to be stronger we increase at the same time the mass and then the inertia forces.
For this reason it is very important that I introduce for the first time worldwide on the construction, an unlimited power moment of stability without mass, to additionally help the moment of stability of the cross sections around the nodes.
2) The size of the tip torque of the wall lever depends ...
a) by the magnitude of the inertia force (resulting from the acceleration of the ground and the weight of the mass of the structure)
b) from the height where the mass is from the ground
c) From the dimensions of the wall in height and width.
Let's take an example.
A wall 10 m high and 3 m wide receives an inertia force at the top of 50 tons.
What will be the magnitude of its tipping torque?
Inertia force X height / width 50 X 10/3 = 166.7 tons.
That is, the mechanism of the invention together with the cross-sections of the nodes should together create a moment of stability greater than> 166.7 tons so as not to overturn the wall.
Here we see that the width of the wall works beneficially in reducing the force of the tipping torque.
If we had columns instead of a wall, the tipping moment would be three times greater!
Conclusion In large walls and buildings made entirely of reinforced concrete, the patent is more efficient than in columns.
Basically a large moment of stability is created by three contracting aggregates, such as that of the patent mechanism, that of the wall width and that of the cross-sections, around the nodes.
3) Another factor that causes deformations is the bending of the trunks of the bearing elements.
The bend is created by the elastic and inelastic deformation of the body of the elements during the displacement of the floors
There are two methods to stop the deformation caused by the bend.
a) Place large walls instead of columns that bend easily.
b) Apply a similar amount of compression to the cross sections of the walls to eliminate the tensile strength of the walls.
Without tension there is no bending.
The necessary strength of the sections so that they can absorb the additional compressive forces is ensured by the quality of the concrete,
from compacted concrete,
from the sufficient coating concrete, but mainly from the size of the cross-section which the wall has sufficiently.
The compression in the sections is applied by the mechanism of the invention, stopping any bending of the wall.
Without bending, there is no shear failure in the cross section or shear failure in the coating concrete, caused by the ultra-tensile strength of the steel.
Stress in the cross-sections also improves their resistance to the cutting base, improves the trajectories of the oblique tension and increases the active cross-section of the wall.
4) The soil compaction mechanism ensures a deep foundation (better than this base in width) by improving the bearing capacity of the soil.
The drillings that we have to do for the installation of the mechanism, reveal to us the quality of the soil, as well as the dangers that the soil hides, such as caves and running groundwater which can gradually remove the foundation soil causing landslides.
