What is new .... Example
* If you have a sheet of paper placed on a table.

If on the two ends of the paper, stick two upright wooden parallelograms.
After ... If I shook the wooden table that parallelograms to oscillate,
will see the horizontal plane of the paper is deformed into an S shape
(Torque to the hub)

If we now do the opposite.
That put the parallelogram horizontally on the table, and stick at both ends, two vertical sheets of paper.
If you shook the table, we see the papers defacing the vertical axis in Figure (S)

In both cases, the angle at nodes stressed by a torque, which causes the weaker section deformed.

Now if,
In the first experiment screwed upright wooden parallelograms, with the table (at both ends) will observe that if you shook the table,
paper will not deform at all nodes.
The latest experiment is the method that I say,
and eliminates the torque at the nodes.
This is an extra equation balance on the balance equations we design today
What is new.
I do not clamped plate with the column to release seismic energy.
I do the following.
I make very small cross-section columns to be more flexible (in ductile carrier.)
It is not right to put small sections with large rigid sections together.
because (No isometric allocation charges)
I distinguish ductile operator of the rigid body for several key reasons.
I design the ductile separate entity to be more ductile than what it is today.
I design the ductile carrier separately to take only vertical loads.
Make the rigid body stiffer with pretension.
I use the rigid body, to receive only the horizontal and oblique loads.
Basically, I give distinct roles in each structural system,
so, one being free of the other
Question .. what is best
embedding .. base - soil
or anchoring roof - ground.
For me it is better or anchoring roof - ground.
The anchorage, roof - ground stops the oscillation.
The anchorage, base - soil, not
This is something new in seismic design.
Example ...If you have a wooden stick, like the ones we make
bows , and keep it from one end of our hand .
If you shook your hand this rod will begin to vibrate .
If now tie a string at both ends of the bar and stretch the string will build an arc .
If wag after the bow , you will notice that it will be stiff .
This I did in construction, and stopped rocking .

Now if this string vertically penetrated the center of the bar ( without pretension of the limbs) would not stop the oscillation of the rod .
What causes this phenomenon ;
Equilibrium equations is the great need of building
