646m, the most extreme spot for skydiving. Too bad it’s now gone. :(

There are different stories about the collapse. I personally read of successfully replacing the main rope with two temporary ones, but then hours after workers left the area one of the temporary ropes slipped off of it's clamp, causing the disaster. This is why there were no killed or injuried, as everybody had left the site prior to the collapse. Also I heard that the signal wasn't getting it's way to the Antarctica, but it could have been received in the north and central Africa. The mast was never rebuilt, after years of waiting they finally replaced it with another one (actually an array of two "half-wave" masts) near the city of Solec Kujawski (/solets kooyavski/). You can still receive it at 225 kHz, AM band of course. It's not as powerful as the old one, but I believe it still covers most of Europe and maybe even larger area. Greetings from Poland.

Is it possible to validate the result of this simulation against images of the collapsed tower?

I definitely agree with you. If you put garbage into your simulation/model, you will get garbage out of it. Additionally, if I had chosen a different cable to detach at the start, I'm sure the collapse would have looked entirely different. However, the goal of this simulation was less scientific and moreso for entertainment/educational value. Still, you will see in photos of the real collapse that the mast remained in large undamaged segments as seen in this video.

Amazing video

This is fascinating and a great video. I don't understand from an engineering perspective why there wasn't redundancy in the design. It seems like losing one guy wire should not cause an almost immediate catastrophic failure of the structure (I know there were other factors involved, but still). You would think the structure itself should be able to resist some deformation, and that the numerous guy wires are simply there for added stability. But then, I'm not an engineer so what do I know XD

@Contraflex

7 ай бұрын

I think under normal loading conditions, the failure of a single guy wire would not cause the entire tower to collapse. However, once the tower was struck by the extreme wind gust while the guy wire was missing, it resulted in the tower being displaced enough to cause progressive collapse. It likely would have been too expensive to design the tower to survive this extremely unlikely scenario; a potentially one in one thousand year wind gust happening at the same time as a guy wire being replaced (which would presumably only take a few hours to replace). Technically the structure could be designed to withstand a one in one thousand year wind gust without any guy wires, but it would require extremely large steel members and would be very expensive; at that point you are no longer designing a guyed mast, you are designing a skyscraper.
