Abstract
The design method of applying artificial compression to the ends of all longitudinal reinforced concrete walls and, at the same time, connecting the ends of the walls to the ground using ground anchors placed at the depths of the boreholes, transfers the inertial stresses of the structure in the ground, which acts as an external force in the structure's response to seismic displacements. The wall with the artificial compression acquires dynamic, larger active cross-section and high biaxial stiffness, preventing all failures caused by inelastic deformation. By connecting the ends of all walls to the ground, we control the eigen frequency of the structure and the ground during each seismic loading cycle, preventing inelastic displacements. At the same time, we ensure the strong bearing capacity of the foundation soil and the structure By designing the walls correctly and placing them in proper locations, we prevent the torsional flexural buckling that occurs in asymmetrical structures, asymmetrical floor plans, and metal and tall structures.Compression of the wall sections mitigates the transfer of deformations to the connection nodes, strengthens the wall section in terms of base intersection shear and shear of the sections, prevents stress at the ends of the walls by introducing counteracting compressive forces. The use of tendons within the ducts prevents longitudinal shear in the overlay concrete, while anchoring the walls to the foundation not only dissipates inertial forces to the ground but also prevents rotation of the walls, thus maintaining the structural integrity of the beams.

"The decade’s earthquakes around the world have put first priority of the major social and economic issue of the seismic behavior and the overall seismic protection of structures against earthquake disaster. Due to the necessity of containing the effects of the seismic we have developed various methods to optimize the response of structure motions. According to modern standard, the seismic design of building is based on the capacity design and ductility requirements. The inevitable inelastic behavior under strong seismic directed to items and failure mechanisms. In short, the earthquake acceleration is converted into stored energy in node structure. The shift holds each section in any part within the elastic region, all energy stored in the structural framework will be released at the end of the cycle in the opposite direction, the inelastic zones. When the seismic energy is too large, it will produce excessive movements that will cause a very high level curvature in the vertical and horizontal elements. This means that the rotation of the sections of the column and beams will be out of normal elastic range, with problems of the construction safety, particularly in phenomena such as earthquake, tornadoes and very strong crosswinds.
In an earthquake, the columns lose their eccentricity and their bases are lifted, creating twisting in all of the nodes of the structure. There is a limit to the eccentricity, that is, there is a limit to the surface area of the base which is lifted by the rollover moment. To minimize the twisting of the bases, we place strong foot girders in the columns. In the large longitudinal columns (walls), due to the large moments which occur during an earthquake, it is practically impossible to prevent rotation with the classical way of construction of the foot girders. The following result occurs with this lifting of the base in combination with the elasticity. When one column of the frame lifts one end of the beam upwards, at the same time the other column at its other end moves violently downwards. This stresses the beam and has the tendency to twist it in different directions at the two ends, deforming its body in an S shape. The same deformation occurs with the columns also, due to the twisting of the nodes and the differential phase shift of vertical plates. In order to prevent the lifting of the base, we clamp the base of the structure to the ground using the patented mechanism. However, if we want to prevent the lifting of the whole columnar structure which stems from the lifting of its base as well as from the elasticity of its main body, then the best point for enforcing an opposing, balancing force is the roof. This opposing tendency on the roof must come from an external source and not applied from within the structure. This external source is the ground underneath the base. From here the external force is applied. Underneath the base of the structure, we drill a hole into the ground and clamp it with the patented anchor. With the aid of a cable which passes freely through a pipe in the column, we transfer this force which we obtained from the ground up to the roof. At this point in the roof, we insert a stop with a screw to prevent the raising of the roof of the longitudinal columns which happens during an earthquake and deforms all the plates. In this way, we control the oscillation of whole structure. That is, the deformity which the structural failure causes. With this method, we do not see changes in the form of the structure, because it maintains the same shape it had prior to and during the earthquake. The reaction of the mechanism to the raising of the roof of the longitudinal column and the opposing reaction of the at the bottom part of the base, divert the lateral load of the earthquake in the strong vertical section. With this diversion of the lateral load of the earthquake to the vertical columns, the twisting of the nodes is abolished because the lateral loadings of the earthquake are 100 per cent borne along the length of the columns, so it is impossible for them to twist in their main sections.
And the method, the prestressed columns do not have ductility, and cannot absorb energy. What I do to solve this problem. Simply, Ι do not apply pretension between the roof and drilling. What am I doing? First apply pretension between the level of the foundation base (ground) and the anchor mechanism which is in the depths of the hole of drilling. The pretension is twice than it is the axial loads I want to receive the tendon in an earthquake. The initial prestressing applied to achieve very strong adhesion (Clamping) of the anchor into the walls of the borehole. Then fill the hole drilling with Concrete. After uniting the tendon that extends from the borehole, with a nut, to lengthen until the roof. We take care of the tendon to pass through a plastic tube free, so to avoid guilds (adhesion) with this concrete. On the roof, inserted between the tendon and the roof a spring which simply tighten with a screw. Do not apply any other N. L. Ioannis 327 second pretension. The spring on the roof leaves the column to oscillate inside the elastic range while applying seismic damping because it prevents the rise of the roof of the long column. But stop the column to pass on inelastic failure region."
Dear Ioannis Lymperis ,
Congratulation to your reasolution!
I think you have found an excellent solution...
You have done the construction that I had when I wrote the following to you:
'Thank you for your discussion... In it your explanation is very logical and good, I have no experience in architecture, but I have ideas about how to design buildings that can withstand earthquakes. We witnessed some of the events that took place during the recent catastrophic earthquakes in Turkey. You can use this information to decide whether you meant what you meant... It is worth travelling to the site and paying attention to the traces left by the earthquakes in the buildings. And if you have an idea that wasn't quite accurate then correct it.'
(https://www.researchgate.net/post/Are_you_sure_that_we_are_planning_the_anti-seismic_structures_correctly)
Yet I did not reveal my idea to you:
I have the feeling that we have similar parafenomenal abilities (?)
Have you ever had the feeling that someone writes an article about something, and when you read it you know immediately what the person really meant when they wrote it?
Have you received any financial reward for this work?
But the rule should also apply to intellectual work, that if someone comes up with something, it should be rewarded financially.

You understood very well dear Dr. Samy Elhadi Oussadou
Basically by compressing the cross-sections we stop the deformation of the body of the wall, and the transfer of this deformation to the nodes where the walls connect to the beams which are deformed by this deformation of the walls. On the other hand, we increase the capacity of the walls to receive the base shear and shear failure. We still stop the tension of the sides of the walls by imposing opposing compressive balancing forces. We ensure that longitudinal shear failure will not occur in the overlay concrete, since the tendon freely penetrates the concrete through a pipe. By anchoring the ends of the walls to the ground we ensure 1. The diversion of inertia into the soil 2. The prevention of the turning of the walls which affects the deformation and destruction of the beams. 3. We ensure strong foundation ground
Dear Dr. Samy Elhadi Oussadou
I also really enjoy exchanging scientific analysis with you!
Dear Dr. László Attila Horváth
My friend I have paid a lot of money in research in experiments and patents but I have not got any money yet. In Greece, where I live and come from, there is no conflict. They think everything I say is bullshit.
I would love to contribute to the anti-seismic reconstruction of the affected people in Turkey if I am invited
Dear Ioannis Lymperis ,
Today the world has become a very wrong one. Those who are close to positions of power, they steal the inventions and good ideas of those outside.
That's why I didn't say at the time that idea like yours. Currently an unskilled worker with a few elementary classes, has much more income than me.
It seems that the leadership of the European Union is interested in destroying European countries!
Regards,
Laszlo
Dear Dr. László Attila Horváth
I completely agree with you!
In Greece, all serious inventions do not have a happy ending.
Ioannis Lymperis
Indeed very good abstract and discussion
You deserve the best talent.
Godspeed
Dear Dr. Rasha A Waheeb
Thank you so much for everything you do!
The feelings are mutual !
