"The bridge was constructed using an innovative approach called accelerated bridge construction (ABC), meant to reduce potential risks to workers, commuters and pedestrians and prevented traffic tie-ups in the area."

Seems to be working. It reduced the risk quite a bit by falling before pedestrians could be allowed over it, saving many life's had it been full

the Chinese have literally mastered pedestrian bridge technology, every major roadway in cities has one every couple of blocks to keep psychotic Chinese pedestrians and bicyclists away from psychotic Chinese drivers. there is far less congestion and accidents and its way easier to navigate across busy intersections than having to rely on crosswalks.

Good thing I'm on spring break.

Are they died?

Thank goodness.

they obviously used top quality design software to simulate this bridge before building it

this sort of innovation?

Are you implying male engineers haven't fucked up? How much do you want to bet that the vast majority of engineering disasters happened at the hands of male engineers?

doesn't fucking matter. Fuck off with your disinfo

learn how to build you morons

Fuck off back to your containment board.

obviusly more faults were at the hands of males, but thats because there are more male engineers.

Its like saying there are more male F1 champions than female. Duh theres more fucking male drivers. o na percentage basis women probably make more engineering blunders than men because women dont think logically.

the proper contention to make is the rate of engineering disasters at the hands of men is higher than the rate at the hands of women.

female civil engineers are pretty rare, thats like saying men get more piss on the toilet seat than women or something

Has the driver in the picture stopped screaming yet?

>nice positioning

Hard to say this early, there'll have to be a full investigation to determine what the failure point was. Should be noted that the bridge was very much incomplete at the time of collapse, pic related. Either it was:
1. Material provider fuckup, issues with the quality of concrete/tensioning lines
2. Contractor fuckup, someone didnt follow the instructions to support the bridge during construction
3. Engineer fuckup, possibly load/stress calculations were off and the bridge couldnt support itself without its (not yet built) support members

ayyy watcha doin there rabbi

Spontaneous structural failures (as in, nothing hit it or set it on fire) are incredibly rare and almost always boil down to something installed improperly or bad engineering (Tacoma Narrows, that hotel skybridge, the Minnesota I-35 bridge). Question is which one and whose head rolls for it.

>The span has to literally be held up by jacks

Fucking retarded.

Those were the lifts used to put it in place. But yes, either they didn't design it to hold up under its own weight and forgot to pay mind to the construction, or they falsely thought it would hold up under its weight during construction. It looks like the central column for suspension wasn't merely missing due to a construction delay, but was purposely meant to be constructed with the section in place, at which point it couldn't possibly have been suspended.

The collapse could've probably easily been avoided if you had simply put a temporary support in the off-limits lane in the middle.

Apparently they were using a new mix of concrete as well; could have been a factor if its testing was fudged/faulty

>and forgot to pay mind to the construction, or they falsely thought it would hold up under its weight during construction.
I believe the issue was that they began performing stress tests on the bridge, and the stress tests caused the bridge to fail.

Because, obviously, you perform stress tests on the actual bridge when it's on location and there's traffic driving under it.

>Because, obviously, you perform stress tests on the actual bridge when it's on location and there's traffic driving under it.
And in half-finished state with the cables missing.

you mean

>plane hits it
>controlled demolition happens
>it falls down

You could actually stress test the individual parts as long as the tests are designed for those incomplete parts rather than the finished bridge.

Actually, it's pretty reasonable when you have a pre-made road deck that you set into position at its destination. You'd want to have some idea that the road deck is in good condition and up to standard before you go through the effort of moving it to location and putting it in.

that's such an overcomplicated and ugly design for a pedestrian bridge

i expect some miserable local government stooge forced them to open the road despite it clearly being incomplete

It pretty obviously is Trumps fault.
He starts import tariffs on steel.
Builders now have to use american steel.
American steel is sub-par. Way sub-par.
Bridge collapses.
THANKS TRUMP.
Also: we're gonna need source on those claims of female incompetence. Funny nonetheless.
Also: off course trump had nothing to do with this fuckup. Just rustling some jimmies.

>that's such an overcomplicated and ugly design for a pedestrian bridge
And why is that?

>Cable stay bridge.
>Delete the first two words and build it.

Right.

Regular building steel doesn't get imported. It's all high grade steel for special applications like machinery.

It looks like they didn't install any suspending cables from the central spire, so half to most of the weight of that half of the bridge they had up was resting on just its endpoints. Perhaps they did this in the interests of speed, and perhaps it could have been made to work, but only under extremely ideal conditions. I think they way they designed its assembly is likely at fault.

Actually the entire weight was resting on the end points. That wasn't the issue though, the issue was bending moment. In other words the thing collapsed from bending downwards in the middle from its own weight, just like a high jump bar does from its own weight.

I say half to most as I'm including the glass walls and complete roof they had in mind in the "full" weight, but yeah, that's basically what I was thinking. They had ways of holding up that weight available to them, but chose not to take them.

An arched steel truss bridge would have been sufficient. The main span could have been pre made off site. Then hoisted and assembled in one night.

Engineers arent very smart. They're just glorified artists at this point, with no real world or practical thought put into any "design" that comes out of their ass

>It looks like they didn't install any suspending cables from the central spire
They didn't bother building it.

>Engineers arent very smart. They're just glorified artists at this point, with no real world or practical thought put into any "design" that comes out of their ass
You're thinking of architects, you shit eating clown. Engineers are the ones who desperately try to make architectural nightmares work in real life.

Judging from the steel rods sticking out of the bridge section where the spire would be, it seems like it was supposed to be built after the section was in place for God knows what reason.

>Actually, it's pretty reasonable when you have a pre-made road deck that you set into position at its destination.

Yeah. But the bridge was fabricated next to it's installed location, then rolled into place. I'll bet engineers speced leaving the transportation equipment in place until after installing/tensioning the cables. And the management said, "That'll block traffic for an extra day or two. Move equipment out first. Then put in cables."

Point me at the part of the road that has even the slightest attempt at making a foundation for the supporting structure and you have a case.

Nope. ;)

Some fucknut got people killed.
