Tall wooden construction takes all the new frontiers
What began as a struggle against the excessive carbon dioxide emissions, today went much further. Tall wooden construction around the world takes all the new frontiers. Melbourne (Australia) built a wooden apartment building Forte height of 10 floors.
London (England) also stands nine-wooden house Stadthaus. But they are not surprising. The shock of the appearance of the wooden "candles" miracle wormed among the stone jungle, replaced perplexity about the intention to replace the stone in the construction of a tree in principle. But Michael Green (Michael Green), architect from Vancouver (Canada), says that this is not some kind of obsession there, and well-founded decision.
For example, the Americans are trying to intrigue the project of wooden high-rise building, which is not destroyed by the earthquake, as many of its stone

At the University of Alabama (USA), Dr. Tang Tao (Thang Dao) and Dr. Sriram Aaleti (Sriram Aaleti) using a giant laboratory for experiments with projected fragments of wooden skyscraper. Their task - to find out what should be the design, so that the house was not affected by natural disasters in seismically dangerous areas. But this is the first good news. The second good news - is that in the course of two technologies of construction of wooden buildings and Tao Aaleti research for the first time combine: a lightweight wooden frame structure (LiFS) and cross-glued panels (CLT). Scientists are confident that with their help built house is indestructible as a rock.

Meanwhile, the new draft of wooden high-rise buildings are already starting to offer the company, which previously built of steel and concrete. Company Skidmore, Ownings & amp; Merrill (SOM), which designed the tallest building in the world - Burj Khalifa (Burj Khalifa) in Dubai (UAE) - plans to build a 42-storey skyscraper made of wood. However, in order to secure the building construction will include all elements of concrete, the use of which, anyhow, will be minimized. And another project - a 18-storey wooden hostel Brock Commons, designed by Acton Ostry Architects - is already under way is realized on the territory of the University of British Columbia in Canada. In 2017, the building, the construction of which will cost 51, 5 million Canadian dollars, lodges 404 university students.

Along the way, the builders hope to break down the stereotypes associated with the risk of fire of wooden houses. Their arguments sound as if they had never been fires 1493rd, 1547 th and 1591 th, utterly destroyed "wooden" to Moscow, while in 1775, the year Catherine II ordered not to "build stone houses».
< br> On the contrary, if you listen to David Barber (David Barber), chief engineer for the fire safety of the American company of Arup, the danger is just a house, which use designs and elements of steel. This is so because even at 600 degrees Celsius began to change the structure, and with it the load-bearing capacity, despite the fact that the fire in the hearth fire temperature reaches 1000 degrees. Therefore, for steel structures protection is required, otherwise they will just melt.
But wood protection, it appears, does not need! This proves normal wildfire during which externally burns wood to a certain depth, but does not die and does not fall. Moreover, inside the tree layer is maintained, contributing to the subsequent regeneration.
Knowing this, according to Barber, enough to add to the cross-cementing of the additional spare bed and wooden buildings, the fire will be uneasy.

Known for its commitment to the wooden housing construction general Michael Greene admits that developed the latest technology wood panels - almost eternal material! However, this eternity - forced. In the case of the destruction of wooden structures, carbon dioxide, which It absorbs like a sponge, gets back into the environment.
So for life after would be logical to dismantle the wooden skyscraper on parts, which can then be used as building material for other objects. Probably, it sounds bold, but courage, as you know, the city takes. Michael Green, by the way, has already won Paris with his project 35-storey wooden skyscraper called Baobab. It was built from cross-glued panels (CLT), which will be produced at the factory and delivered to the site ready-made kits. Green says that the construction process will be something we recall inat assembling IKEA furniture, and will not take much time, and so will save on production work.
