If you design a scale specimen to do a seismic experiment. What should you look for to make the experiment reliable?
1.In microscale experiments should you do everything in microscale and the displacement between two points?
2.The models must have the scale within their structure, so that the sub-scale intensity of the earthquake causes corresponding sub-scale displacements that agree with elastic theory ?
If anyone knows the rules of microscale seismic experiments it would be very useful for me to know them. Thanks a lot!
Dear Dr. Samy Elhadi Oussadou
Thank you for the answer.
Acceleration is a function of oscillation amplitude and frequency in unit time.
On the microscale
The amplitude of oscillation must be under scale;
Does the frequency remain the same?
I did this experiment on a microscale of one to seven.

Base oscillation width 15 cm, 30cm go and 30cm come full route go come on 60cm with a frequency of 2Hz and sometimes it reached 3 Hz. At 2Hz the natural acceleration of the experiment was measured at 2.41g
The question is the 2.41g of the experiment under scale, how much physical acceleration does that correspond to, in a normal sized building?
Do we multiply 2.41g by the scale of 7 = 16.87g?
Is that right or wrong?
The work of E. Barkovsky shows that an earthquake is actually a gravitational explosion. Therefore, it cannot be tested in “microscale” models.
Dear Dr. Alexandr Yagodin
I'm not talking about an earthquake and the unpredictable factors it has.
I'm talking about specific acceleration on a scale.
Dear Ioannis Limperis. Due to the impossibility of transferring density and deformation properties to a “smaller scale”, you will get a very large approximation. The model will not be similar to reality.
Sincerely.
Alexander Yagodin.
Уважаемый Иоаннис Лимперис. По причине невозможности перенести плотностные и деформационные свойства в "меньший масштаб" Вы получите очень большое приближение. Модель не будет подобна реальности.
С уважением.
Александр Ягодин.
Dear Dr. Alexandr Yagodin
I agree that I will not have the same effect as reality.The question is whether it comes close to reality ?
I did two experiments with the same seismic test specimen.
One experiment with my method and one experiment without my method to get comparable results.
The comparable experiments show something more, I think.
Still the acceleration I did the experiment at was too much for the earth's seismic data to see strengths. Of course I don't have a large mass which increases the tensions too much.
With my method. https://www.youtube.com/watch?v=KARShWGN2yc&t=10s
Without my method. https://www.youtube.com/watch?v=l-X4tF9C7SE
Do you think the comparable results come closest to the truth of the method's usefulness?
Secondly I did rock traction experiments with a new anchoring mechanism of my own.
I applied a 100 ton pull but the traction bars failed.
