Tall buildings are built with deep foundation systems. Taipei 101 has 380 1.5m diameter piles tied into a 3m thick concrete raft that creates its basement. The piles rock socketed into some 40-60m below the structure. those piles are socketed up to 30m into the bedrock.
It is designed to resist high earthquakes and typhoons. The damper changes the mode of the vibrations to reduce the peak stresses. If an earthquake is going to destroy the foundation there is nothing the tuned mass damper can do. If the entire building is leaning it almost certainly a write off and will be demolished.
I watched a very tall building near me get build. The pounded in 20m piles into the bedrock with a gigantic hammer, for 12 hours a day for many days. It was amazing to see those massive lengths go deep into the earth, and also it was amazing how rythmic pounding for days will drive you insane.
The Millennium Tower piles do not rest on bedrock, it was supposed to use friction with the soil instead. This is cheaper and CAN work but it is far easier to get wrong than having the piles rest directly on bedrock.
Yo -- when I mentioned Pence and Montana... Iknow several people who owned places in the building, and drank next to Montana in the residents' bar with.... im very familiar with the building
And if you need a very secure location to lock your bike up in SF (which is a good idea) ring the security bell in the parking breezeway near the dumpster, the security guard will open the door - the lock your thing to the stand they have
(LPT: anytime youre in SF rather than use a bike rack outside (people steal your saddles)... drop$5 to check your bike in with a bellhop at a nice hotel.... and they will accomodate you for a week..
so fn funny ; people downvote this, LPT - but YSK bikes these days are in the $15,000 range...
Mine is $8k and its the low med range of bike...
So seriously - if you are spending on your kicks like that, make friends with a bellhop so you dont go through the agony of having a bike stolen from you.
If youre in the bay area... MikesBikes is your friend
