Wait, what?

1. China has more or less already recovered.

2. China makes most of the worlds steel.

3. The more accurate title would be "Souring Metal Prices spell trouble for Biden's infrastructure plan".
----------------------------------------------------------------------------------------------------

"The cost of everything needed for China's post-pandemic infrastructure boom, from steel and coal to glass and cement, is soaring."

Sorry, but China is leaning away from infrastructure boom, and working on a smart-infrastructure boom, which is mostly in fiber and cloud infrastructure.

In another video, in the interior of an apartment, the fittings were swaying. I don't know it is shown in this video.
All tall building sway. I lived on the 28th floor of a building once and some days the light fixtures from the ceiling will swing around

How about this issue of "sand shortage" being peddled by the usual suspects. I watched the whole video and as I watched the whole time I couldn't help thinking that somehow, someway China will be blamed for this s..t and soon enough China was indeed mentioned and not in a positive light. It's expected for the wester shills and fake environmentalists that developing countries ought not to raise or improve their infrastructures since it'll bring about the degradation of natural element like sand. While they continue demanding for more flat screen sets, IPHONEs that must be changed annually etc. The west is all talk and no action.

The Humen bridge had excessive vibration not too long ago and the bridge was closed for a while pending investigation. The panel of experts found that the temporary road barriers laid on the bridges were the culprit that caused resonance problem. Problem seems to be resolved with removal of those temporary structures.

It could be that certain alterations were made in that building that could have changed its vibration characteristics . Maybe it is due to the two large mast on top of the building.
Are new buildings constructed by this building in the last several years? With new buildings, it will change the air flow and wind patterns around existing buildings. Which if hits the natural resonance frequency of existing building could sway it. It is the job of the engineer/architect to ensure new buildings won't negatively affect existing structures.

I think this is the most likely explanation. A 20+ years old office building is a likely candidate for renovation or upgrade.

A less likely possibility could be changes in the environment around it, e.g., changes to air flow due to construction of new tall buildings nearby.

I was watching the video, and it really did not show any discernible sway, perhaps the videographer was moving the camera too fast.

If it was really swaying, wouldn't there be debris around the building as glass and concrete gets shifted or loosened from their settings?

How did this whole thing start? It was a bit odd that I did not see any law enforcement on the ground directing the evacuation, at least I did not see any of those strobe lights. By the way it looked, more people could've been hurt by being trampled.....

We really are hairless monkeys, panicky at the slightest of instinct.

Yea, with all the tall building going up in China, they might need to build a scale model of the 1km radius and test it in a wind tunnel against all existing structures as part of the engineering certification. Same should be done for UV due concave nature of certain building surfaces.

Maybe they already do that?

Pretty sure it was not done 20 years ago.

That is not standard practice unfortunately for most areas. It is required in Canada for downtown areas that are built up. But all Chinese cities are built up, they should do something like that as standard.
