There will be 500-story skyscrapers

Thanks to new construction materials, future skyscrapers can be 500 stories high, like vertical cities.

Vertical city

The city council is reviewing three designs for 135-storey houses that will grow adjacent to the central park corner. The design drawing of De Simon & Chaplin - one of the world's leading skyscraper companies (NCT) - is most appreciated, being promoted to complete the technical and economic argument. and is more likely to exist.

All three buildings are on the orders of construction tycoon Donald Trump. But someone mentioned 150-storey houses, erected 500 meters high in the city . If indeed, then New York's "Big Apple" has the highest NCT record on the planet, with past thanks to the Chrysler Building (1930 - 345 m), Empire State Building (1931 - 412 m) and more recently with " Twins " - World Trade Center - WTC (1972 - 451 m). "In the past half century there has been no major change in height. From the Empire State's 102 floors to 110 floors of Sears Tower, with an increase of only 8 floors - Hari Wees, the brilliant Chicago architect "The only change was in morphology, the skyscrapers became more elegant and more diverse," said the former, who built the 480-meter-tall Sears Tower in 1974.

According to H.Wees, today we stand in front of the "leap" of height, which people recently thought could not be achieved. Thanks to new, lighter and more durable construction materials, as well as new types of structures and higher-speed elevators, 150-200-story buildings have achieved technical features.

Tens of NCT - Super High are in the design process, including a 210-storey house in Chicago by H. Wees. " The building I designed - H. Wees said - is actually a vertical city. It requires separate power plants, telephone and post offices, sewers and independent pipelines ." Two other famous architects, Robert Sobel and Hag Crall, have spent six years poring over the idea of ​​a 50-story " Great Statue ". R. Sobel, who was involved in creating WTC New York, said: " From the vision of the structure, only the sky is our limit. The 500-storey giant building we are drawing is set. Next, there could be thousands, because today we have enough solid construction materials, as well as enough construction techniques. A half-mile tall house will be built not far from Houston, can present as a tower, in the form of triangle-linked cylinders, leaning on each other and fighting against the wind ".

"Swinging in the wind"

From the structural point of view, the problems of the NCT structure are divided into two: vertical load generated by gravity and surface load generated by wind (or by seismic). If reinforcing steel and cement are resistant to pressure, it is not a problem. So the solid structure of a NCT depends primarily on the ability to withstand loads from surfaces. It is strange for those who are outside the profession: the most annoying thing is . the wind. At a speed of 160 km / hour the wind can shift the top of a 300 m high house, deviating a meter from the vertical center.

Of course, in the case of an earthquake, it gets worse. All ELs in the world today are "swinging" in the wind. For example, WTC New York (which was hijacked on September 11, 2001 by the hijackers) ranged up to 10 seconds, while City Coral Buiding was 6 seconds. For wind pressure to be "saturated" (otherwise people living on high floors will suffer from a disease like seasickness - hypertension, and dishes and photo frames will jump .), ants architects create huge holes in all the high parts of the house; or "attach" more concrete blocks (such as City Coral Building - 400 tons), "controlled" against the wind - creating a balance for the roof of the NCT.

Other technical issues

There are still many other issues related to the use of an NCT court. One of the two towers of WTC New York previously had 99 elevator chambers, but with a 200-story house there must be at least three more times: a two-story elevator like a two-story bus, serving two floors simultaneous. There will be a very fast elevator system with a speed of 700 m / min, stopping for example at 25, 50, 75 floors . From there, the transition to adjacent floors is done by other stairways with smaller speeds. .

But the increase in speed causes diseases of blood pressure, dizziness, tinnitus . especially when it's cold. So there must always be a certain level of pressure in lift chambers - not the same as on airplanes, this is not simple, because the doors are always open and closed. Fires of fire can only be solved with the creation of "fire zones" every 20 floors. Because in the event of an alarm, tens of thousands of people in a NCT could not run at the same time through the main door, but they could stay in special areas - capable of withstanding about 3 hours against smoke. and fire - wait for rescue groups to .

Social Issues

After the "surprise" was erected, NCT - super high will encounter inherently difficult social problems. The traffic in the area will increase dramatically immediately, resulting in traffic congestion problems and pollution levels. The supply of domestic water is also a problem worth mentioning, when taking out a huge amount of water and how the pipeline system can withstand under a "devilish" pressure? The worry spread to the aviation industry. JF Kennedy International Airport Board always insisted that the New York City Council should not deal with the licensing of new super-high-level NCTs, as it would jeopardize aircraft and helicopters.

And lastly, will those who want to live in such "cloudy" houses - where the rent of offices has not offset the construction costs? Super billionaire D. Trump once said: " In America everyone wants to do something unusual, but no one dares to do something wrong to live in the tallest house in the world !".
