China LITTLE OOPS


By on Sunday, June 19, 2011

Like This One. What happens when there's not enough metal in a concrete component? Well, they found out at the Lotus Riverside residential complex on the outskirts of Shanghai, China. The 13 story building wound up lying on the ground! Anybody who bought a condo here sure had a problem. Talk about a collapsed market!
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 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 tilt. Then it began to shift and the "hollow"
concrete pilings were snapped due to the uneven lateral pressures

And thus was born the eighth wonder of the world.
