Higher and Faster

Construction the 828-meter skyscraper of Burj Khalifa, the tallest so far in the world, took more than 5 years. The Chinese experts plan to create the 838-meter building of Sky City in only 90 days through the use of modular technology. On the problem of the construction accelerating of high-rise buildings also work researchers of the American Purdue University, West Lafayette, Indiana. Scientists believe that the tested technology will allow commissioning 40 – 50-storey buildings if not as impressive pace, as in China, but still 3 – 4 months faster than it is now.

Researchers are perfecting a new technique that could speed construction of skyscrapers while also providing enough stiffness and strength to withstand earthquakes and forces from high winds.

The project aims to develop a new kind of “core wall,” a vertical spine that runs through the center of skyscrapers, said Mark Bowman, director of Purdue University’s Robert L. and Terry L. Bowen Laboratory for Large-Scale Civil Engineering Research.

A skyscraper’s core wall supports a portion of the building’s weight and enables the structure to withstand lateral forces from strong winds and earthquakes.
