8/19 blog round-up.

The first core part is on, they are higher then the outer steel tubes that where already on. So we had some actual growth again yesterday.

I'm finding that I'm more interested in this project than any other because the construction is so unique. However I had expected that they would take down the scaffolding on the lower portion as they progressed upwards but they're not doing that. It makes me wonder if we really won't see what it looks like until the entire thing is topped out and then they would have the massive job of removing hundreds of these covered platforms where the workers connect the pieces together. The planning and logistics of this tower must be mind boggling and they're obviously taking alot of precautions for the safety of the construction crew.

no it was constructed to collapse when an earthquake occured. Damn, what a stupid question! Do you really think the city would approve a tower which isn't safe enougt to withstand such events?

Yeah, but Tokyo would never approve anything that couldn't withstand earthquakes.

The progress here is unbelievable!

If the drawings are correct that were posted a few pages back, we should see that the lowest parts of the upper scaffolding will be removed after the current level is completed.

~~~~~~~~
And the tower is protected against earthquakes and typhoons by a very sturdy foundation that should be able to withstand horizontal and vertical movements. Plus the design of the tower is based on the three storied pagodas that you see at Japanese temples that are known to withstand earthquakes remarkably well.

Thanks for the info. Yes, the Japanese have studied how earthquakes affect any manmade structure and probably know more about it than any other nation. I remember seeing a documentary that described how the height of a building will change how an earthquake will shake it. The most vulnerable buildings are not modern skyscrapers, they're shorter brick and mortar structures that have no flexibility whatsoever and will simply collapse. That's why in poorer and less developed nations even a moderate earthquake can kill thousands.

東京スカイツリー内部にある階段室を、「五重の塔」の心柱になぞらえて名づけられた“心柱(しんばしら)制振”という新制振技術が採用されています。外側にある鉄骨の本体と中心にある鉄筋コンクリート製の円柱が別々に立ちバネのように伸びちじみする168基のシリコン製ダンパーでつながっています。これにより、大地震時にタワーに働く力を最大で40%程度低減できるようになります。更に断面は下の方は三角形でなるべく風を受けないように上に行くほど丸くなっています。また更に三枚の杭が三枚の壁で一体化され先端にいぼをつけた「連続地中壁杭」と言う技術で地中35mの硬い地盤に50mまで差し込んであります。そして更にアンテナの一番上に重りを起き揺れを打ち消すように振動させます。大地震が起きても、柔軟性のある構造により、倒れないようになっています。

nice photo, don't think I have seen it from that view before.

I have started to make a LEGO model of the Tokyo Sky Tree, which is at a scale of 1:125, or just under 5m high.

wouldn't the correct question be 'How big an earthquake is this structure designed to withstand?'
because even an ultra strong building would still have a limit on how much it can handle.
