ANSWER: Dear Prashant S Akerkar
Goodmorning and Fraternal Greetings!
Thank you very much for your question. My answer is as follows to the best of my knowledge and understanding.

Your question itself is a Paradox to science.  It is not possible to construct 100% Earthquake resistant proof buildings and structures. So far we have experienced the major earthquakes in the world and estimated the intensity of the same and designed some of the structures in USA, Japan etc. but Our human knowledge is limited and we can’t predict what will be happened tomorrow?????.
So far we could not invent any machine or system which can predict the occurrence of earthquake.  Experience in past, earthquakes has demonstrated that many common buildings and typical methods of construction lack basic resistance to earthquake forces. In most cases this resistance can be achieved by following simple, inexpensive principles of good building construction practice. Adherence to these simple rules will not prevent all damage in moderate or large earthquakes, but life threatening collapses should be prevented, and damage limited to repairable proportions. If major earthquakes are occurring more than our expected/predicted intensity it is our duty to design more and more strong buildings and structures as per the case specific. There is no end for the nature’s abnormality as we can neither predict nor control.

QUESTION: Dear Dr. D S Subrahmanyam

Is it possible to renovate/redevelop already built structures viz buildings,
bridges etc for earthquake resistant proofing ?.

i.e. Structures which are more than 3 years old.

Awaiting your reply,

ANSWER: Dear Prashant S Akerkar, Goodmorning and Fraternal Greetings!

Ofcourse , yes. We can design and renovate the buildings and structures according to intensity of earthquakes. But lot of parameters and scientific studies and good expertise is needed. Ground Vibration studies with various intensities should be conducted near the structures. Expertise Civil engineering is required for the same.

QUESTION: Dear Dr D S Subrahmanyam

Thank you.

Are Quality certifications awarded by Civil consulting cos for
Earthquake resistant proofing to Builders ?.

i.e. Quality certification indicating "This Structure
is certified for withstanding earthquake of magnitude 7 by
XYZ Civil Consulting co".

The above is just a example from my end.

Awaiting your reply,

Thanks & Regards,

Dear Sir, Goodmorning and Fraternal greetings!

In China there are many artificially fabricated houses which can withstand the earthquake intensity of 9.0 also. And these structures are certified by local Government authorities just like ISO:9000 certification by following simple elements, i.e

(1)   characterisation of ground shaking; (2) structural analysis under ground motion; (3) behaviour of structural systems; and (4) earthquake-resistant design and construction.

But in Japan, I have seen recently there was an article regarding the earthquake resistance building which I have given as follows.

“Korkem Tau” residential complex has recently been certified as a magnitude 9 earthquake resistant building. The complex is built in Almaty in accordance with the Japanese construction norms and rules. Constructed by BI Group jointly with Kusto company, the complex is an example of modern approach to earthquake resistance of buildings. The structure of the building is a reinforced concrete monolithic system in the form of main cross walls and the foundation is a monolithic reinforced concrete slab put on 25 meters long bored and cast-in-place piles. It ensures maximum resistance of the facility. This technology is used in construction of skyscrapers in Japan. Presently, four 6-storey houses of “Korkam Tau” complex have been commissioned. All the design documentation was amended by a special computer program. Well-known Japanese architect Kazuo Watanabe handed over the certificate of earthquake resistance. Mr. Watanabe takes part in implementation of “Kokrem Tau” project as an independent expert and personally supervises the process of construction.
Kazuo Watanabe believes that Kazakhstani builders are well-qualified for construction ofmagnitude 9 earthquake resistant buildings. According to him, the owners of the project (BI Group and Kusto Group companies) are very meticulous about the quality issues whether that be seismic resistance or final finishing, geological tests of quality control. These are the factors that attracted attention of the Japanese architect and induced him to accept the invitation to take part in the project. For this reason, the construction site in Almaty became a platform for introduction of Japanese innovations.

With regards
