2 meters wall of new UBC concrete withstood nearly triple the strongest quake ever recorded

The material is called an eco-friendly ductile cementitious composite (EDCC) and is so strong and flexible that it acts like steel, bending during an earthquake instead of crumbling like concrete.

Walls that are sprayed on both sides with the material performed so well in seismic tests that UBC engineers dubbed it the ‘unbreakable wall.’

Soleimani-Dashtaki had to turn the dial to three-times the magnitude of the strongest earthquake ever recorded in order to break down a two-meter wall of EDCC in seismic tests.

The technology developed at UBC will cut retrofit costs in half, added UBC civil engineering professor Nemy Banthia, who supervised the EDCC project.

Thank you, it's a very interesting article!

My patent reacts differently. With the method of designing, clamping the top-level nodes with the ground, I hope to divert the lateral inertial stresses of the earthquake into more powerful areas of the structure than those currently driven. These strong areas have the ability to absorb these tensions (preventing and relieving the relative displacements (ie drifts) and thus the tension that develops throughout the vector is limited) and returning them to the soil from where they came by subtracting in this way, great tensions and failures over the load-bearing structure of the building while ensuring a stronger bearing capacity of the foundation soil. With the appropriate design of wall dimensioning and their placement in suitable locations, we also prevent the torsional buckling that occurs in asymmetrical and metallic high-rise structures. Basically, when the roof is connected to the ground through the patent rope, it limits the displacements of the floors (ie the drifts) and thus the intensity, which develops throughout the carrier, is limited.
MEASUREMENT OF ACCELERATION, POWER (F), Moment of inertia
See this video that has frequencies on the screen The 7 Hz frequency is ghosting at the frequency that my experiment had towards the end of the video.
video with frequencies https://www.youtube.com/watch?v=2c8qtIduEHM
My own experiment. The higher frequency is after 2.40 seconds and frequency is queried at the 7 Hz frequency of the other video https://www.youtube.com/watch?v=RoM5pEy7n9Q
So ... In a natural earthquake I did the experiment with a 0.22 cm oscillating amplitude and a frequency of 7 Hz we have ... a = (- (2 * π * 7) ^ 2 * 0,22) / 9.81
3,14x2 = 6,28x7 = 43,96x43,96 = 1932,4816x0,22 = 425,1460 / 9,81 = 43,34g natural earthquake
The specimen in the experiment had a general mass weighing 850 kg. The second floor because of the inverted beam it carries is more pounds than half so I would say it is about 450kg and the ground floor is 400kg So to find the inertia force F first on the ground floor we say ...
F = m.a 400x425 = 170,000 Newton or 170 kN.
and the first floor 450X425 = 191250 Newton or 191.25 kN.
Total force F (Inertia) 170 + 191.25 = 361.25 kN
Moment of inertia
Strength X Height ^ 2
Ground floor 170X0,65X0,65 = 71,825 kN
First floor 191,25x1,3x1,3 = 323,21 kN
Total Inertia Torque 71,825 + 323,21 = 395 kN

The axial loads N (kN) of the vertical tendons for the following cases of virtual residential buildings are provided in a table, in order to deal with a very strong earthquake:
A. Case Design of a building 10.00m × 10.00m, square with nine (9) columns on a 5.00m grid and eight (8) tendons (see Figs A1, A2).
A.1 Ground height 3.50m
A.2 Two-storey, total height 7.00m
A.3 Three-storey, total height 10.50m
A.4 Four-storey, total height 14.00m
A.5 Five-storey, total height 17.50m
A.6 Ex-storey, total height 21.00m

B. Case Plan of a building 20.00m × 20.00m, square with twenty-five (25) columns on a 5.00m canvas and twenty-four (24) tendons (see Figures B1, B2).
B.1 Ground floor height 3.50m
B.2 Two-storey, total height 7.00m
B.3 Three-storey, total height 10.50m
B.4 Four-storey, total height 14.00m
B.5 Five-storey, total height 17,50m
B.6 Four-storey, total height 21.00m

Let's really talk about absolute earthquake technology.

It is a method that uses a mechanism for joining the upper ends of a reinforced concrete wall with the ground in order to send in it the upward tensions created by the torque of the wall to prevent large displacements and tensions of the wearer occurring during the earthquake .
We have placed on a table two columns, one column screwed on the table, and the other simply put on the table. If one shifts on the table, the unbolted column will be overthrown. The bolted column withstands the lateral loading. We do exactly the same in every column of a building to withstand more lateral earthquake loading. That is done, by simply screwing it to the ground.
Basically, when the roof is connected to the ground through the patent rope, it limits the displacements of the floors (ie the drifts) and thus the intensity, which develops throughout the carrier, is limited.

Tensioning between of the upper edge of the walls with the earth reduces the displacements responsible for all the stresses that develop on the structural carrier.

The patent is stacked into the ground to draw from it a force that transfers it to the upper end of the wall in order to apply a counterbalance to the torque of the wall
One cubic meter of reinforced concrete weighs 2400 kilos. The steel reinforcement in it is about 140 kilos per cubic meter. Empirically if you multiply the number of 0.25 by the square meters of each floor then you will find the cubic meters of concrete. In the end, add + cubic meters of the bases.
So if we have a building skeleton with a floor area of ​​100 square meters, if we multiply by 0.25 we will see that it consists of 25 cubic reinforced concrete weighing 25 x 2400 = 60000 kilos or 60 tons. Steel reinforcement is 25x140 = 3500 kg or 3.5 tonnes. That is, 3.5 tonnes of steel for 60 tonnes of concrete are needed.
A cable winch (crane) weighing 3.5 tons, how many tons of weight could it lift? Answer = Thousands of tons. (not dozens)
Conclusion Concrete has a lot of reinforcement in it that has the ability to lift the weight of the construction hundreds of times But the constructions in large earthquakes suffer damage.
Something is wrong in the study done by the civil engineer.
What's wrong? Imagine a man drowning in the sea. A civil engineer will throw the rope into the sea and leave without holding the edge of it. They do the same with the constructions. They put a lot of steel reinforcement without wrapping one end into something stable from which they could gain strength.
The method with the mechanism of this patent is what it does, which is not done by mechanical engineers. The patent is stacked into the ground to draw from it a force that transfers it to the roof to stop the drifts and the tensions that deform the structural bearing elements.
You've heard that they say (the drowning of his hair is caught) Somehow, they are building the construction today ... many irons for little benefit. One has to explain to them that they have to tie one end of the rope on a firm and strong place. (like ground) This is what I'm trying to explain 10 years! But some have not yet understood it. If they do this with less steel they will have more effective results with the earthquake.

Τhe patent achieves the following

1)The consolidation of the nodes of highest level of the walls with the ground, using the mechanism of the invention, deflects the upward tensions created by the wall overturning torque transporting them freely and directly from the roof into the ground and in this way stops the displacements responsible for all growing tensions on the body of the bearing elements which they cause inelastic bending deformations and failures in a major earthquake.
2 ) Also the mechanism and method of anchoring provides very strong foundation in soft soils
3)The wall receives only compressive stresses at both ends a) at the upper end b) and the facing lower end near the base. Does not exist anymore tensile strength. This means that there are no longer torques in the nodes Does not exist anymore mechanism of concentric forces failure The floor mechanism (soft floor) does not exist anymore
4) Does not exist anymore coordination because the whole construction is shifted with the same frequency and the same oscillation amplitude
5) The wall also receives horizontal shear forces. Apply tension at all edges of the wall with the patent mechanism increases the ability to horizontal shear forces.
