Building toppled over.
Just got this e-mail this morning.
Dear Brothers and Sisters:
The next time someone belly-aches about onerous regulations, show them this! And, remember to thank all of the Engineers – Structural, Mechanical, Electrical, Environmental and Resident – who help prevent this from happening to us!
In Solidarity,

YES, IT IS A 13 STORY BUILDING LYING ON THE GROUND.
(1) An underground garage was being dug on the south side, to a depth of 4.6 meters
(2) The excavated dirt was being piled up on the north side, to a height of 10 meters
(3) The building experienced uneven lateral pressure from south and north
(4) This resulted in a lateral pressure of 3,000 tonnes, which was greater than what the pilings could tolerate. Thus the building toppled over in the southerly direction.
First, the apartment building was constructed
Then the plan called for an underground garage to be dug out.
The building began to shift and the concrete pilings were snapped

The excavated soil was piled up on the other side of the building.
Heavy rains resulted in water seeping into the ground..The building began to shift and the concrete pilings were snapped
Due to the uneven lateral pressures.
The building began to tilt.
And thus came the eighth wonder of the world.
If the buildings were closer together there would also have been a domino effect.The building began to tilt.
And thus came the eighth wonder of the world.
They built 13 stories on grade, with no basement, and tied it all down to hollow pilings with no rebar.

Lateral earth pressure may have been the cause of the failure, but some of the piles look bent, so they are likely steel piles, not concrete. That is why they are hollow and don't contain rebar. It might be that the material the building was founded on wasn't properly compacted so the combination of water and nearby excavation undermined the building foundation and the thing toppled over.
Edit: The soil under the building was probably unsuitable, which is why they founded the building on piles, not directly in the soil. High lateral earth pressure may indeed be the cause. Or the piles weren't driven deep enough.

Still, that's quite something. I think I'm embarresed for China on at least a weekly basis. One day they'll probably be more powerful than the US, but for now, they're just kind of a joke.
