The Japanese have been planning for a long time to build a huge broadcasting tower in the heart of Tokyo. Not even the tsunami and earthquake that hit the country last year could stop them. With only two months of delay, the Tokyo Sky Tree was built, a structure with a height of 634 meters. The second tallest in the world.
The Japanese had been planning for a long time to build a huge broadcasting tower in the heart of Tokyo. Not even the tsunami and earthquake that hit the country last year could prevent them. With only two months of delay, the Tokyo Sky Tree was built, a structure with a height of 634 meters. The second tallest in the world.
The first place, as we know, belongs to Burj Khalifa with a height reaching about 830 meters. However, the Tokyo Sky Tree is not much inferior to it, and in addition, in the urban landscape of Tokyo it is probably even more impressive than the symbol of big money of sheikhs from the Middle East. Moreover, the Sky Tree is at the very top of the list of tallest free-standing towers.
The author of the building is Obayashi Company ().
The new building is 34 meters taller than Canton Tower in Guangzhou, China, and almost twice as tall as its predecessor, Tokyo Tower. The tower is intended to transmit a signal to Tokyo and the surrounding Kanto region.
Since the terrain on which the structure was built is considered to be very unstable, the engineers had to take care of extraordinary strength of the structure. They used an element called shinbashira, a central column that has been used in traditional Japanese architecture for centuries – it is characteristic for buildings such as pagodas. And in fact, there is no historical record of such a building ever collapsing during an earthquake (and the tallest of them reached a height of 55 meters, being built entirely of wood).
The Shinbashira located in the Sky Tree is a hollow concrete cylinder with an elevator and stairs inside. Interestingly, it is independent of the outer shell, as it is attached by shock absorbers.
The strength of this structure has already been confirmed during last year’s earthquake with a magnitude of 9 on the Richter scale. The tower was not affected at all, although construction dragged on for an additional 2 months.
The building, which is to be opened for visitors in May, will have several attractions such as an observation deck as well as stairs located on the outside of the tower.
Interestingly, at one time the world’s tallest building (this record was held until the construction of Burj Khalifa) – a radio mast in Konstantinov – was 646 meters high, making it taller than the Tokyo Sky Tree. Unfortunately, as we know, in 1991 it collapsed due to operational errors. And so we would have had something to boast about to the world.
