Yeah I don't think I'll trust the developer's words.China skyscraper wobble due to 'winds, rail lines and warmer weather'

Could a tuned mass damper be added after it's built or does the building kind of have to be designed with it?
According to a quick search, retrofitting dampers is a thing that has been done.
I've been in buildings in NYC that sway with high winds, it's a different feeling than those videos showed. That's vibration - especially in that footage of the antennae moving quickly - that's not sway.
Good luck people - stay the fuck away from that building, it's going down at some point.

Who else is going to get forced into the building other than people who work in it?
They do, which means the panic around it moving is based on something out of the norm.
in one of the videos it looked like there was some residential. i could be wrong tho
Yeah I feel like this is supposed to happen...but not to this extent.
My friend lives in Prestige tower in Toronto (just off the lake) and she's on the 60th floor if I recall. When there's wind off the lake you can slightly feel the building moving, but when you look out the window at the same time is when you really see the movement...it's crazy. I was a little concerned the first time it happened lol.
This place is shaking stuff inside apartments though, which seems odd.
The provincial government conducted the investigation. Projects like these are typically approved by the city government, but it is possible that one or more city officials involved are in the provincial government due to promotion. From what we know though, there is no conflict of interest.
Still periodically wobbling with the investigation continuing.

Rents falling drastically but I certainly would never work or live in a build that wobbled like this no matter how attractive the rents are.
Tenants of shaking Shenzhen tower seek compensation as probe continues
Many tenants selling electrical goods in SEG Plaza want to be compensated for business disruption and early termination of their leases after the 72-storey skyscraper began mysteriously swaying on May 18.

If there is something that is not lacking it's office spaces in Shenzhen. Having said that for stores thing are different.
If it's like any other type of electrical mall I have seen in China it's a small ecosystem of related small business concentrated in a few mall floors.
Will need some coordination to move them at same time.
Every building (every object really) has it's own resonant frequency (we use this to make cell phones vibrate), typically you either design it in such a way that such a frequency is never reached (the exact frequency is dependent on the shape and materials etc) or you use damping methods to dissipate the energy etc.
Typically when a building like this is designed they find out what the natural and resonant frequency is and change it from there and add any dampers etc if needed for these long skyscrapers. The fact this seems to have occurred unexpectedly means someone didn't do their job properly.
I used to work in a 10 story building that was out in the middle of nowhere. It got a little scary on windy days as doors would refuse to close and the elevator would be slower than normal. Not gonna lie when I say I found excuses to nope the hell out of there when there was an official wind advisory for the county.
There ain't no way I'm going up that thing.

Maybe its just me, but I cant see anything in that video.
Camera is shaking too much to see wobbling.

You generally can't run diagonally on a gridded street system. There are buildings on either side of the street.
How can you know which way a sky scraper gonna fall?
If you worry about a tall building falling on your head you want to get as far away from it which is a straight line in any direction.
Someone fucked up the FEA. Not enough care from engineering firm or regulatory.
I remember the the Dancing Plague of 1518 too
Party Rock Anthem wasn't that long ago, come on
the building's been there for over twenty years though without these issues.
It's actually due to the shape of it. If you look at it from above its designed to break the wind and prevent the low pressure zones that cause wobbling in most tall uniform buildings (like the Taipei 101)
The edges of a box(building) are stronger than the faces. Likewise if the wind is going to topple a building, its going to exert the most force on a larger surface area.
20 years isn't that long engineering wise. When you design a building or facility for a large construction project you design for it's it's expected lifecycle and decommissioning. It's unlikely that building was designed to last for only 20 years.
What's with Chinese infrastructure being fucked up lately?
If i recall correctly we had the glass bridge being shattered and a guy trapped there, the regular bridge wobbling due to strong winds and now this in a matter of weeks.

Skyscrapers are fucking scary. I think I have a real phobia of them. I get freaked out just standing near them when they are perfectly fine. Looking up at them makes my stomach drop. Can't imagine the fear seeing that shit in person
Huge country + Lots of recent infrastructure expansion = Lots of potential places for fuck-ups
Perhaps vibrations from nearby underground rail lines weren't considered in the calculations.
I hate it when the villain in movies dies stupidly. It's so cheap. I don't remember much from that movie but I remember groaning at that.
