The supertyphoon lechma is the king this year and the third most powerful typhoon that has landed in east china since its founding. The first high-rise building in china — the shanghai central building — which has been the subject of much attention as a result of the typhoon, has a new record。
After two days of double-checking and rigorous measurement by the staff, the daily newspaper liberator, a journalist, was identified from the shanghai center building: the so-called “fixed-up-the-hysteres” of the shanghai center building, which showed the largest display since its inauguration in 2016 on 10 august。

What does it mean to have a big blocker
The structural technical director of the shanghai central building, song weining, indicated that the unilateral set-up of the blocker was one metre. It was calculated that during the period of the “licima” impact, the blocker had been set unilaterally over 50 centimetres, with an instant peak of 70 centimetres, the largest ever recorded since the opening of the shanghai central building。
Interceptors, one of the brightest installations, are found in the central building of shanghai, where “all are treasures”. The skyscrapers can reduce high-level swings and help the super-high buildings to maintain stability and security。
Song weining said that the brakes were mainly affected by a combination of wind forces and direction. This was the largest record since its launch, and the power of the lichma is evident. “on 10 august, according to our monitoring, the prevailing winds in shanghai center were at a rate of 40 metres per second.” journalists have looked at the information and found that the speed of the wind is comparable to that of a strong typhoon。
Prior to the “licima”, the greatest display of the blocker was during the past year's effects of typhoon “abbit” and “winbya” — a unilateral display of over 40 centimetres. At that time, the prevailing wind in shanghai centre was at a rate of more than 20 metres per second. According to expert estimates, the entire building was set at 40 centimetres and 50 centimetres, respectively, by typhoons。
So how much swing did the shanghai central building get under the influence of "licima"? Journalists have learned that the final results have not yet been measured, but are expected to exceed last year。
How do you cut the brakes
Interception is a physics term that refers to the decay of power and the dissipation of energy, which means buffer. There are only two skyscrapers in shanghai, a high-rise forest, equipped with a barrier: the shanghai central building and the worldwide financial centre。
The introduction of electric vortex-tale-trainers in the shanghai central building for the first time in a wide variety of global types is also an innovative technology in my country. In simple terms, the wind functions mechanically on buildings, which eventually translates into thermal dissipation, through a resistance system。
According to data provided by the shanghai construction unit on the construction side of the shanghai centre building, such a blocker could reduce the wind peak acceleration by more than 43 per cent and allow 90 per cent of the building to feel greater comfort。
Do you need a high-rise blocker
Now that the blocker can cut the swing of the building, does it have to be installed in a superstructure? According to the experts, super-high-level wind resistance relies mainly on building structure and external design and requires “self-hard”. The role of the detachor is more like “bridging” by cutting swings, optimizing experience and improving the quality of the building, on the one hand, and increasing structural durability, on the other. In accordance with the relevant national regulations, there is no compulsory installation of a barrier in the building。
Many of the world's famous super-high buildings have been equipped with blockers of some different types. For example, in some countries there are multiple earthquakes and more seismic effects are taken into account in the design of a barrier. Many typhoons in shanghai are designed to be more wind-resistant, so they are also called wind-trainers。
The country's first large wind-trainer, installed at the 101st building in taipei, was the world's largest wind-trainer and the first such facility to be opened as a tourist attraction in the world. In the light of the taipei experience, the shanghai central building's wind blocker, which was inaugurated in 2016, is also open to society and is a public space for a collection of science and art exhibitions。
The figure is the wind blocker for the 101st building in taipei. The building has a huge steel ball weighing 660 tons on the 88nd to 92nd floors, using swing to slow the building's swing
Today, on the 125th floor of the shanghai central building, this was visible. There's also an art device on the top of the blocker, called the shanghai hye-eye。
