The ultimate seismic method
The invention applies compression to the sides of the diaphragm walls andsimultaneous anchoring to the ground using piles with deep expanding anchorages in order to stop the deformation which causes failures and collapse in the earthquake.
The 7 indisputable achievements of this new seismic design are listed below.
1) Dynamic response from the ground without the presence of mass whichintensifies inertia in the earthquake This is a remarkable achievement.
2) The deflection of the forces of inertia in the ground stops the deformation, the stress and finally the failure of the bearing elements.
3) The control of the displacements of the floors in each cycle of seismic loading, with dynamics coming from the ground makes it possible to minimize the eigenperiod in the coordination.
4) The problem of shear failure that occurs in the mechanism of relevance (steel concrete cooperation mechanism) is eliminated due to the high resistance of steel to tensile, which turns the failure into a shear cause. The method I use only applies compressive strength to the concrete cross section without any shear stress.
5) The shear failure also occurs in the cross sections where there are tensile stresses. The method I use applies a force of compression to neutralize the tensile forces.
6) The base shear is a key failure factor which is quantitatively eliminated by imposing compressive stresses on the cross section.
7) Improving the bearing capacity of the ground by constructing stronger and more zones of influence under the base, prevents failures from landslides.
To stop the deformation which is responsible for the failures and the collapse of the structures, we must stop the bending of the cross sections of the bearing, as well as their moment of inversion, which is created by two opposite forces, that of inertia on the one hand, and this territorial acceleration on the other hand.
To stop the bending more effectively, we use rigid walls instead of columns.
To stop the tipping moment more effectively we use walls instead of pillars, on which we impose compression + anchoring to the ground at all their ends.
The walls are the most rigid, and have a double lever, (that of height and that of width)
These two advantages of walls help us to stop bending and tipping more effectively than if we use pillars.
In the anti-seismic research laboratory at the
Technical University of Athens, a simulation was performed to draw useful conclusions for this method.
But they did not understand the full method of operation of the invention and made me a simulation which does not fully represent the design method I mention.Instead of installing walls, which bend and overturn as difficult as possible,they installed columns, which bend and overturn as easily as possible.
They also removed the anchoring of the columns with the ground.
The only element of this method they considered was the imposition of loads on the cross-sections of the columns by the nodes of the upper level.
However, without using the complete design methodology, the shear of the base was quantitatively improved, the bearing capacity of the construction was significantly increased, and the displacement of the control node was significantly reduced.
