Wow we need a professor to tell us that fire on metal will make it weaker. What we need is for tanker drivers to slow down on exit ramps that have sharp corners, especially if loaded with fuel.
I am a retired FDNY Captain, and the prof is correct. Steel weakens at 1000 degrees and losses 40% of its weight bearing capacity. As temps get higher the steel softens and warps from the weight stresses upon it. (Just like WTC) That section the steel was only carrying its own weight, (steel and slab), yet it collapsed as they always do. (Lookup the many prior highway collapses over the past years). Anytime you have unprotected steel it is at risk from heat -degradation. (Like WTC) These fires are way too common, and show how easy it is to shutdown our road networks. To learn more on WTC see my books, MY TURN ON THE FIRELINES 1980-2003, and the series FATAL FLAWS Books 1-3 B&N
Richard, bullshit! As a welder, the steel will only weaken if the heat is directly on it for an extended length of time. This didn't happen in this case.
@@morales1961 just curious, how, as a welder, do you know when steel weakens? We're talking about structural strength here, not melting a pool or bending something with a torch.
@@morales1961 Your wrong, because you are thinking as a welder. Fires are a different animal. That fire burned very hot, 1400+, and was trapped under the concrete which allowed that intense heat to absorb and radiate the length of the steel. Only the beams exposed to the air might have cooled some. We had dozens of fires in Bldgs that the steel only supported the roof, but they still warped and failed from the heat.
@@lowandslow3939 25 years of firefighting and years of schooling. We had dozens of fires in NYC where the steel failed even though it only supported the normal roof. In this case the steel was covered by the concrete, which trapped the heat making the heat degradation worse. There is a great shot of WTC 2 from the East that captures what Structural Engineers call the moment of failure. You can see the columns bending as their strength weakened to the point of failure. Then gravity takes over.
I don't think you want to use China's rapid building projects as examples. They are known to have many problems with quality. A similar incident to this occurred a few years ago on incident on I-85 in Atlanta. It was rebuilt in 43 days. That doesn't mean this will only take 43 days but it does suggest that this could be a couple to a few months. Much of that may depend on finding a steel fabricator who can shift their manufacturing around to put this work at the front of the line.
Looks like pre fab concrete pieces also. It’s not poured there on-site , made elsewhere. Heat always a factor on iron. They should all be sprayed with fireproof monocote on beams etc.
WHY WAS THAT TANKER PARK THERE AND HOW DID IT GET ON FIRE , WHO THE OWNER NO ONE IS ASKING THE REAL QUESTION IS WHY AND HOW ? WTF WHO IS PAYING FOR THE REPAIRS .
It crashed there! The driver lost control coming down an exit ramp that has a sharp curve at the end. He will likely going to fast. The truck flipped over, tank ruptured and 8500 gallons of gasoline caught fire. The Federal Highway Administration (so taxpayer dollars) will likely pay for the repairs. The Feds, state and city will then all seek reimbursement from the truck company's insurance provider.
It's not 100 years old. We didn't being building the Interstate Highway system until the 50s. If you use street view on google maps and go under this bridge you will see that the steel is fairly new and was in very good shape. This bridge was just replaced 10 years ago. 8500 gallons of gasoline burns at temperatures well over what is needed to weaken steel and cause it to collapse. But with hundreds of thousands of steel bridges in the country this occurrence is so rare that we don't protect against it.
And you wouldn't want to drive over it as a result. No doubt that the Chinese build some good stuff, but the stuff they build really fast has had numerous problems with quality.
@timpula9984 oh are you from China? When comes to engineering it's not made like shit they make cheap shit for American consumers but they build amazing things quick and efficiently
What we can see why are colleges are not good got somebody else with an accident trying to explain something here in the USA I guess we don't have experts here
What kind of professor is he? He knows petroleum fires burn at 1400F max and steel does not get soft below 2000F? Those girders he is talking about are bent like spaghettis. Explain this please. Until than it is a crime scene and nothing should be removed.
43 days to replace a similar collapse on I-85 in Atlanta a few years ago. Not saying this will be done in 43 days but it certainly won't take 5 years. It's likely a 2-5 month fix depending on whether there is damage to the surrounding abutments that support the beams and how quickly they can jump to the front of the line of a steel fabricator to get the new beams.
More like a year.....that road is now extremely compromised so they should take the time so a catastrophic accident is avoided in the future instead of just patching it up!!!

Apparently we need both. Even after the prof folks in the comments still don't believe a petro fire has the ability to weaken steel!
I often wonder if some of these "accidents" are not really accidents. After 9/11 I am suspicious of everything.

Well, that was a pointless interview.
I hope he didn't get paid for that because he said nothing!
😂😂😂
China built an entire hospital in 30 days and we can't repair a section of concrete on one of the busiest highways on this side of the u.s.

Less than 48 hours, ohh you guest it a bridge 😆
The city probs ain’t got a lot money
China isn’t exactly renowned for their safe construction methods.

@@talkswithry2409 It is an Interstate Highway. Majority of the funding for such roads comes from the Federal and State governments, not the locals.

That few months comment going to get him in trouble.

@@timpula9984 op likely didn't want, or expect, actual answers
That freeway looks 100 years old. The city didn’t think this would happen especially with the fires? 🤦🏽♂️

Yeah. Intense heat will weaken concrete and steel. Not really that hard to figure out.
Months? If they have the right people in place it should take 6 weeks. Look at the I85 in georgia collapse for an example.
This same thing happened in Tampa by the airport. Expect that road to be out of order for a good bit of time - like longer than you think it should.
Omg. Was anyone hurt????
China have that fixed in a week

Did they find that ammonium nitrate yet 🤔🤔
It was not an explosion. So put away the conspiracy theory.

Colleges aren't a panacea, but they can help with grammar and communication.
Get Elon musk to build it he can do it in a few weeks

He's an engineer.
@@yvonneplant9434 he’s a 🤡🤦🏻♂️
Among other things, you may want to check your units and assumption that all petro fires are created equal.
Bro, it’s just like a couple of planes hitting buildings and making them collapse like a controlled demolition.
This is an unfortunate accident. Hope everything is well for all.
The best and the worst of times!!!
Bunch of BS 🤬
50$ that is done in 5yrs lol

Biden’s America…
Biden's America will now fix it. As tRump goes off to prison.
Presidents aren't in control of tanker truck drivers taking a sharp curve at too much speed, loosing control, crashing and creating a fire.
What about concrete beams in the future?
