In 2019, for the first time in the CIS, together with the International Association of Experts in Earthquake Construction, the Kazakh Research and Design Institute of Construction and Architecture and the State Institute of Earthquake Construction and Engineering Design and OJSC Promproekt successfully conducted a large-scale vibration test on the seismic platform of our design to determine the seismic resistance of 9 points. During the test and based on the results of the analysis of the data obtained, all experts and test participants unanimously noted that the reliability and seismic resistance of the Karkas.Kg design is implemented at the highest level

Reviews and evaluation of specialists

Head seismic resistance laboratory

Igor Itskov

I am glad that now in Kyrgyzstan, thanks to the company KARKAS.KG, there will be the entire evidence base for testing LSTC. I think now you have made a start, and 40 years later, as you have already conducted tests of this kind in Kyrgyzstan, such tests will begin again, and articles will appear in the world's leading journals again about what tests we have conducted. Best of luck to you and thank you for your contribution to the scientific cause!

Professor. Rector of KGUCTA

Akymbek Abdykalykov

In general, such tests should be open and transparent, we should support each other in the field of science and in the field of earthquake-resistant construction. After such experiments on this technology, you can safely build two and three-story buildings. It can be residential, industrial and sports facilities. I sincerely congratulate you, further discoveries!

Director of SISC

Sydykov Askatbek

Thanks for these tests, we were all convinced of the seismic resistance of the KARKAS.KG construction. I want to note that only the profiles of the KARKAS.KG company passed the tests! Now all doubts are behind, I recommend this innovative construction technology to everyone. I believe that the citizens of the Kyrgyz Republic should live in safe houses!

Director of "Promproekt"

Marat Abdybaliev

At first glance, LSTC did not impress me, but after testing, my attitude towards these structures changed, because I felt that we had received good dynamic characteristics of the building. It has a dynamic effect - it is not inferior to reinforced concrete structures, so you need to work with this system and bring such houses to life!

President of IAEEE

Ulukbek Begaliev

I'm personally attended and participated in these tests and I will say that these tests made an impression on me, since I happened to see literally 16-17 times vibro-dynamic tests for 9 points of LSTK and all my doubts disappeared, now I believe LSTK and I advise everyone as the company KARKAS.Kg thinks about the safety of the inhabitants of our country. I believe that this company will be advanced as they made a step ahead of all construction companies. Good luck and keep growing!

The seismic resistance of the KARKAS.KG building was assessed by official organizations and the best specialists from Kyrgyzstan and Kazakhstan

Experimental studies were carried out on a special vibration platform. The vibrations of the stand were caused by an inertial vibration machine

To compensate for the missing operational loads, 75 sandbags, each weighing 48 kg, were placed at the floor and roof levels.

Two-channel accelerometers (sensors) installed in the building were used to record the amplitudes of building vibrations and register instrumental data.

During vibration tests, the representative building by KARKAS.KG suffered several thousand cycles of intense vibrations, as a result, there were no obvious damage to the building structure.

As a result of the test analyzes by KARKAS.KG, official reports and positive feedback from all test participants on the quality and seismic resistance of the KARKAS.KG building were received.
