But I'm more amazed it was all built correctly by the lowest bidders on materials, sometimes mafia controlled, by the lowest cost workers sometimes still drunk and hungover from the night before.

#22Modern engineering is amazing given the build of knowledge that was needed over a thousand years. But I'm more amazed it was all built correctly by the lowest bidders on materials, sometimes mafia controlled, by the lowest cost workers sometimes still drunk and hungover from the night before.
Kinda trippy to realize this is true for almost everything in civilization.

#25I've felt 4 earthquakes in 2 days. The bigger one was when I was in a department store 11th floor in Xinyi, horrible, horrible. One of the reasons I can't live here permanently. Last year there were much more earthquakes.
Re: Tuned Mass Damper of Taipei 101
#26> Safety comes at a hefty price, however, as the tower’s tuned mass damper cost $4 million to build. A paltry 4 million for a project which cost almost 2 billion (USD); and I imagine it resulted in some measurable reductions in insurance cost. But I wonder, what happens if the entire land that it stands on shifts and is no longer level? That pendulum won't help right a tilted building, and in fact it will move the ce…
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. https://www.civilengineeringforum.me/the-tower-of-taipei-101... https://structures-explained.com/taipei-101-structural-engin...

#27The shape/design was copied by the Westworld designers for the quantum supercomputer "Rehoboam" in season 3. https://www.youtube.com/watch?v=TgBtBkW0u8Y Also - given the large motion of the damper in today's earthquake, why weren't more people freaking out? I'm also curious about how much the dampers (shock absorbers) heated up from restraining the movement of the ball.
Look at japanese engineering that implemented the same concept for their castles... WAY THE HECK earlier...

#29It does need to be mentioned that the Burj Khalifa only needs to deal with winds and does not need to worry about earthquakes where as Taipei 101 does both.

#30A very interesting counter-part design is the Burj Khalifa tower in Dubai that while taller, does not have any dampener at all[0]. It does need to be mentioned that the Burj Khalifa only needs to deal with winds and does not need to worry about earthquakes where as Taipei 101 does both.
