New-york morning

Oldest skyscrapers

Although the term "skyscrapers" is relatively new, and in ancient times it was assumed that the farther into the sky, the better. Built in the 3rd century BC, the lighthouse Faros had a height of 135 meters. In 516 AD er The Chinese, in turn, established a pagoda, which reached 137 meters, and its interior housed more than 1,000 rooms.

Space skyscraper

If a few decades ago someone had mentioned the idea of ​​hanging a skyscraper on an asteroid, he would have taken first place in a lineup to a psychiatrist. Meanwhile, NASA is already planning to direct the asteroids so that they rotate around the Earth. At the same time, a concept has emerged that allows a self-sufficient building to be connected with such asteroids. It will use solar energy and get water directly from the clouds.

Skyscrapers and earthquakes

Taipei-101

People have a justifiable fear that an improperly prepared building could roll over or collapse as a result of an earthquake. Until the completion of the construction of the Taipei 101 skyscraper, the place where it was located was absolutely calm, "seismically quiet." The number of small earthquakes tripled during construction, and after it was completed - in 2004 - several cases with a magnitude of 3.5 points were noted at once. But the danger of collapse during hurricanes and earthquakes compensates for the 660 ton ball pendulum, which controls the amplitude of the skyscraper oscillation. The fastest elevators in the world work perfectly in it. The speed of 60.6 km / h allows you to get from 5th floor to 89 in 39 seconds. According to experts, the tower will withstand an earthquake, which can be in this area once every 2500 years.

How long does construction take

Building a single-family home can take years, and some of them usually remain unfinished. So how much time is needed to build a skyscraper? Burj Khalifa was built in 5 years, the Empire State Building in less than 2 - and this is considered a very good result. But this is nothing compared to the recent feats of the Chinese developer Broad Sustainable Building. Sky City skyscraper with a height of 200 meters is installed in just 19 days, the speed - 3 floors per day! Of course, this would not have been possible if it had not been for the fact that 90% of the building was built in advance at the factory, and the task of the workers at the site was mainly the assembly of prefabricated elements. Mini Sky City is designed to withstand earthquakes with a maximum magnitude of 9 points.

When the end comes

skyscraper 4 km

How high can skyscrapers reach? Engineers responsible for the largest buildings in Dubai say "above the highest mountain". Already today a project has been created for a building with a height of 4 km and a diameter of 6 km. If it was a residential tower, it could accommodate up to 8 million people. Moreover, for its implementation is already quite affordable technology. The problem is that, in addition to legitimacy, the costs will be astronomical and will amount to $ 1.5 trillion!
