THE HOUSES IN ITALY WILL BE BUILT ON THE TECHNOLOGY DEVELOPED BY AZERBAIJANI SCIENTISTS
President of International Academy of Science (IAS) "Health and Ecology" Professor Walter Kofler (Austria) gave the exclusive interview to "Azernews" newspaper, where he said about the new technology of seismic stable construction "Safe Buildings" developed by Azerbaijani scientists.
Dear Professor Kofler, International Academy of Science H&E suggested to build the seismic stable houses in Italy on basis of the technology developed in Azerbaijan. Why has this decision been made?
On behalf of the International Academy of Sciences "Health and Ecology" I express deep condolences to the people of Italy in connection with numerous victims of the strong earthquake that occurred in August 24 and 24 October 2016.
The international scientific community cannot remain indifferent to the tragedy the people of Italy lived through the earthquake. We understand that Italy is in a seismically active zone, and strong earthquakes in this area are possible in the future. Therefore, new houses built on the site of the old ones must be resistant to earthquakes.
In his speech in August 26, 2016 the Italian Prime Minister Matteo Renzi offered to build the new seismic stable buildings: "The plan "Italian houses" is a serious initiative and not just words. This project will be very well systematized. If the previous government could not do it, for us it is not a reason not to try to help people"
Closely working on the creation of new technologies of seismic stable construction in the Scientific Research Institute of Forecasting and Studying the earthquakes of the International Academy of Science there has been developed a new effective technology of seismic stable construction "SafeBuildings" with the support of NATO grant allocated under the program "Science for Peace" in 2006. The project was successfully completed and accepted by NATO experts. The buildings, built on a new technology, successfully completed pilot tests on seismic platform, simulating strong earthquakes. The result of experiments is that the buildings are not destroyed during earthquakes intensity of more than 10 points on the MSK-64 scale.
The new technology has been designed for large-scale construction for the general population and its main advantages are high seismic stability, simplicity, low cost, not exceeding the cost of ordinary buildings and fast process of construction (www.dbtpro.org).
We want to make a humanitarian initiative and propose to use a new technology on the most favorable terms for the construction of seismic stable houses in Italy.
Our general partner of the project "SafeBuildings" in Azerbaijan is MAKS Ltd. Company, which has been given the right to use the "SB" technology all over world.
Tell us please about advantages of the new technology.
New technology for seismic resistant construction is multinational research project aimed to develop a new effective technology of seismic-resistant construction. There has also been a considerable national contribution to the Project by the Scientific Research Institute for Prognosis and Studying of Earthquakes (SRIPSE) headed by Prof. Dr. Elchin Khalilov.
The main idea behind the Project has been to develop and introduce a simple and affordable technique of designing and building brick houses as well as walls and other structures to prevent them from collapsing during high magnitude earthquakes and strong explosions of various nature, minimizing thereby the number of victims, with the ultimate goal to secure seismic safety of people all over the world, especially in least developed countries.
The technology developed has its name commercially patented as "DANCING BUILDINGS TECHNOLOGY" shortened to DBT with the reference to the fact that during strong earthquakes, those buildings are distorted rather than destroyed and the deformations resemble dancing movements.
Development of a simple technology allowing construction of low-rise (1-3 storeyed) seismically stable houses capable of withstanding earthquakes and, by extension, explosions.
Reducing the prime cost of seismic resistant buildings making thus construction of them available for the majority of local people.
Theoretical and experimental research and comparative analysis of seismic stability of buildings in Azerbaijan, Kazakhstan and Turkey compared with earthquake-proof buildings based on application of the new seismic resistant construction technology.
Concrete outputs were specified in the Project Plan:
Building of a simulative seismic platform with 16 sq.m working area to produce harmonic and random vibrations.
Testing of structures and, finally, model buildings on the seismic platform to access their seismic stability.
Creation of a compact facility for production of seismic resistant blocks, which can be replicated for realization to interested companies and institutions.
Creation of an effective seismic resistant construction technology based on the use of the mentioned blocks for construction of 1-3 storeyed buildings stable to withstand earthquakes with intensity of more 10 by the MSK-64 scale as well as explosions, not costing more than standard seismically unstable constructions.
Development and approval of national technical conditions (state standards) for the new technology and blocks.
We can proudly state that we have fulfilled all that we planned without confining ourselves to the goals initially set. We have developed and tested several modifications of seismic-resistant blocks for different climatic conditions, not envisaged at the start; we developed and started production of damping pads (in addition to semi-liquid damping substance) to be used between the blocks.
How actual is the application of this technology in Azerbaijan?
The problem of safe and inexpensive dwelling easy to construct is one of most important issues in the world. Majority of people residing in Azerbaijan, Turkey, Kazakhstan and other countries of the region located in seismically active zones live in non-seismic resistant buildings. Many of buildings all across Azerbaijan excluding urban areas of Baku, Gandja and Sumgayit are 2-3-storeyed masonry buildings. They are built from bricks, natural stone or construction blocks made of clay and hay and, therefore, are not earthquake-proof.
Assessment of the status of competition among earthquake engineering technologies for 1-to-3 storeyed buildings in Turkey has revealed that more than 95% of buildings are built without any seismic resistant technology applied but rather employing standard techniques: bricks, construction blocks or concrete masonry units. The remaining 5% can be regarded as earthquake-proof.
Buildings of bricks and construction blocks are the most popular in the world and can be found everywhere. It is explained by the simplicity and universality of this kind of construction and its availability to many people. Bricklaying is done by putting bricks on each other using adhesive substances such as cement mortar or glue between them.
Another type of construction widely used in Azerbaijan, Turkey and Kazakhstan is the concrete frame house construction technology. It is as follows: first, the supporting concrete frame of the building and concrete covering between the floors are made. Then, brick walls are erected in spans between the supports.
Neither of the mentioned construction types has proved quite effective during strong earthquakes which keep occurring all over the world.
More than 5,500 people were killed by the magnitude 7.2 earthquake in Kobe, Japan on 17 January 1995. It is no wonder that over 90 percent of the earthquake victims resided in wooden 1-2 storeyed houses which were not seismically stable. The December 2003 Bam earthquake in Iran with magnitude of 6.3 resulted in death of 35,000 people. Again, 90 percent of the houses were 1-3 storeyed masonry buildings made of bricks and clay. Those buildings were not earthquake-proof and therefore almost 100 percent of them collapsed.
The similar situation was observed during the earthquake in Pakistan in November 2005 when death toll exceeded 25 thousand people. The city of Muzaffarabad where over 90 percent of the houses were 1-3 storeyed masonry buildings made of bricks and clay suffered most of all. All of them were destroyed.
The main reason why there are so many seismically unstable buildings all over the world is the lack of a common earthquake-proof construction technique which would be cheap, simple and reliable.
The cost of modern seismic resistant construction techniques is too high and cannot be afforded by local people. In many countries of Middle East, South, Southeast and Central Asia, Africa and Latin America majority of population live in utter poverty, which is why they have to build cheapest houses of available materials. Masonry buildings of brick, clay or wood, inexpensive but seismically unstable, are very widespread there.
Therefore we decided that our efforts would be best put to create a new, simple, potentially popular and affordable technology of seismic resistant construction to build earthquake-proof low-rise houses, walls and other structures with the same or lower price than standard masonry buildings for great masses of population in cities and rural areas.
Thank you very much for the interesting interview
