Equilibrium equations is the great need of building
The loadings (external or static) will always exist.
We can not eliminate loads.
But we can drive loads in sections that are stronger than other sections.
Vertical cross sections of the columns are stronger than horizontal cross sections of the columns.
All structures with nodes lead loads in the horizontal cross section of the column.
The roof - soil compaction deflects lateral earthquake loads in vertical sections of pillars. These sections are stronger and withstand more loads.
As shown in Figure 1

When the column is at stationary state, the static actions are balanced with the opposing forces of soil
As shown in Figure 3

The oscillation of the building changes the vertical axis of the column
See the slope change P that is observed at the regional sides.
As shown in Figure 2

The combination of static actions, Σ with the changes of vertical axis of the column, create the torsional moment P of the node.
How the invention stops the existence torsional moment P of the node.

Clamped column can not be moved up and down because it is clamped with the ground, with the mechanism of the invention.
As shown in Figure 5

The Clamped column with the ground, stops the oscillation of the vertical axis of the column, because the hydraulic mechanism of the invention applies an opposite stress in the rise of the roof Δ ( derived from the clamped anchor in soil ) and another inverted stress in the base Ε

The Clamped column with the ground, transfer lateral load of inertia at the vertical axis of the column, as shear force.
This does not happen with the seismic design of today.
Τhe seismic design of today drives the shear forces at the small sections of the columns and beams.
What design is the best?
1) To plan the seismic design of today drives the shear forces at the small sections of the columns and beams.
or 2) To plan the seismic design of today drives the shear forces at the small sections of the columns and beams, plus...The Clamped column with the ground, transfer lateral load of inertia at the vertical axis of the column, as shear force?
Also ... prestressed construction ...
a) reduces the eigenfrequency construction / soil
b) Increases active behaviour of columns
c) Increases resistance to shear
e) improves the oblique tension
