A eight-lane suspension bridge collapsed in Harbin, northeast China’s Heilongjiang province on August 24, 2012. Three people were killed and five injured when an eight-lane suspension bridge in northeast China collapsed early on August 24, only nine months after it opened, state media said.

Made with high quality Chinese steel.

Looking at this picture again, I can easily see the problem. Look how thing the cross span below the roadway stringers are way too thin and no cantilever gusset supports to distribute the sides of the roadway to the support columns.

“Anyone who even suggests that China is kicking our butt concerning infrastructure is insane!”

You forgot to mention the 20,000 miles of freeway lanes they built just last year - meanwhile we build “bike-lanes”, “bridges to nowhere”, and “trains to nowhere”.

In China the person responsible for building that bridge will probably be executed.

If they were adding extra shovels of sand to the cement or cutting back on bolts to save money, you are darn right they will be executed.

We could use a dose of the Chinese cure for corruption in the U.S.

“I’ve also seen, (in Person), where a concrete support had too much sand and not enough heavy aggregate or the proper proportion of cement literally shatter when the load it was bearing exceeded it’s capacity.”

They’ll just hire the former president of Loral, Bernard Schwartz, to tell them EXACTLY how to formulate re-inforced concrete, just as he taught them rocket staging for their ICBMs.

There’s no shortage of American traitors willing to make sure we get defeated.

I agree with all of you. Here’s another thought: “Where the hell is the rebar?!” You can see only a few rebar in any of the pics.

I think this part (red arrow) failed.

The local suppliers got the aggregate changed and change of specks on rebar coating and protection.

Yep, but it broke at the connecting point of column and cap.

Rustification is the term I learned to describe channels that are formed in the concrete (we used triangular strips of wood) to direct water and prevent weak spots from being used too much by water.

Maybe whatever way was used to attach the downspout was a weakening moment ... a drilled hole ?

Hmmm .. yer right ... no rebar.

That's WORSE than non stressed.

The bridge was not that old, so corrosion probably not an issue. I think Mazda77 is right. The part that sticks-out beyond the column is just to thin and weak. (Looks nice though.) It breaks off and the whole thing tips over. Trucks might be restricted to the right lane where the bridge is the weakest.

On highway dept. work here, test cylinders are made on all concrete for structural work. Design people may not be responsible.

Yeah .. a slump test ... but that doesn't make up for no reinforcement, i.e. .. re-bar.

I think a lot of analysis here is correct (with what we have to go on)

The pictures are very telling.

Heavy lifting begins on Bay Bridge

"At issue is the integrity of the central tower's concrete foundation. On Monday state senate transportation leaders called for a seismic review. The Federal Highway Administration is conducting a review, and in a preliminary report the feds criticized Cal Trans for knowing four years ago that an inspector was doctoring data but failed to take action."

If any part of the six-plus-billion-dollar bridge goes the whole thing falls. That's what some experts say about the unique design.. but boy is it beautiful and fits right in with San Francisco and Oakland. And much of the six-plus billion dollars went to China (probably with a few million circulating back to a certain Senatorette whose husband has umpteen business ventures in Red China). Oh.. and that concrete and steel meets Red China standards.

If you are driving I-80 into San Francisco you can go around a couple of ways and not have to put your life in danger. Hey! Some say that a quake anything near the magnitude of Loma Prieta and it will be gone.

We need pictures from the underside of the flopped roadway to determine if it was the outside of the horizontal or vertical support but then again it could also be what came first, the chicken or the egg.

I would tend to say it is where the vertical meets the horizontal because in theory the greatest moment is at that point and the one on the other side with a close second on the inner intersections of the vertical column. Add the cantilevered forces of the truck weights to the outside.

Is it me or does it look like there is a ripped fabric material exposed in the upper left corner of the picture where the roadway separated?

Rep. Hank Johnson from GA was right - too much weight WILL make THINGS tip over!!!

Why is this called a suspension bridge? My idea of a suspension bridge is the Golden Gate and the Bay Bridge..

What photo number shows the fabric? I’d like to take a look.
(I’ve looked at them all -—— The only fact I see is no
rebar.)
