You mean like the fire in the SS Noronic in 1949 that only took 20 min to turn the steel hull white hot , buckle and sink ?

I believe she had steel decks but was not a battleship or totally connected together in a steel matrix.

After about 20 minutes, the metal hull was white hot, and the decks began to buckle and collapse onto each other. After an hour of fighting the blaze, the Noronic was so full of water from fire hoses that it listed severely toward the pier, causing firefighters to retreat. The ship then righted itself, and firefighters returned to their original positions. By the end, more than 1.7 million gallons (6.4 million litres) of water had been poured on the ship from 37 hoses.
The fire was extinguished by 5:00 a.m., and the wreckage was allowed to cool for two hours before the recovery of bodies began. Searchers found a gruesome scene inside the burned-out hull. Firefighters reported finding charred, embracing skeletons in the corridors. Some deceased passengers were found still in their beds. Many skeletons were almost completely incinerated. Glass had melted from every window, and even steel fittings had warped and twisted from the heat.
Every stairwell had been completely destroyed, save for one near the bow.[ex/]
I want to point out these items, the metal hull, Glass had melted from every window, and even steel fittings had warped and twisted from the heat.

The steel deck

Please clarify this. Heat does not weaken steel? The heat just gets passed on with no consequence to itself?

What a horrible disaster.
Im not sure if the steel itself failed , It just says the steel decks collapsed and from the photo it looks like the steel is still there .
Here the chinese made steel skyscraper was fully ablaze and did not collapse sorry for off topic .

did the deck photo not load for you ? that is twisted , warped steel from only fire. please note there was no impact of any type and no jet fuel on board.

Steel cannot fail from fire. Only thermite/thermate can do that. Nanothermite is extra special so it does it even more better.

I see its twisted and warped yes , Im no expert in steel fires but the energy dissipates in steel skyscrapers , the more steel the better .
I don't see a collapse. The vessel was partially taken apart afterwards, and then the hull was refloated, meaning that the structure itself survived the fire. And this is despite the fact that the interior of the ship was lined with oiled wood rather than fireproofed material.
It took weeks for workers to remove the decks after the fire. You need to examine the pictures that you posted a little more closely, in fact, a LOT more closely, because what you are looking at are pictures of the ship being wrecked by workers after the fire. They spent a long time removing the decks of the ship before they towed the remainder of it away to Hamilton.
Here's one of the pictures that you posted:
Note the 2 pieces of steel on the RHS of the rectangular opening.
Here's a better quality pic of them from below....
For perspective, here is a HQ shot of the dining room of the SS Noronic......
And now, note the shape of the only deformed element in this picture.......
Tell me what, in your opinion as a "fire officer" is common in the failures that you are attributing to fire, and if you can, show me a girder that has failed catastrophically on the SS Noronic.

So I was right then. Others can claim that a coal forge demonstrates that steel can be melted but if I mention surviving woodburner stoves/BBQs/Ovens and saucepans, my post is deleted. Instead we have a new thread ludicrously attempting to compare a ship, loaded with fuel and soft furnishings, and with all its steel with no fireproofing -- with tall buildings. Trust me, ships are not built like a steelframe building. I would certainly expect to see lightweight steel framing in a ship buckling if its coal bunker caught fire.
But however hard you squirm around you will not get hydrocarbon fires in an open atmosphere to melt steel as it does in a forge. And you will not get office (or ships) furniture to burn hot enough or long enough to overcome a large highrise steel frame structure. Even attempting to compare the two in such a thread is risible.

Absolutely not. I looked at this and other images earlier today. Do you see wooden life boats?

What point are you trying to make?

I think he's saying it can't be a fire because the wooden lifeboats didn't burn?
However it seems that the fire was mostly contained within the steel hull, only "breaking through" some windows as illustrated by the photo on this page- so the damage to the boats is probably entirely from radiated heat.

No I don't I do however see several METAL lifeboats.

A building that had it's core fireproofing blown away in the crash and that was full or flammable items like office furnishings and synthetic fabrics. Many synthetic fabrics burn at a higher temp than natural ones. There is a reason that anyone working with an open flame like in soldering, glass working, or blacksmithing will only wear natural fibers.
Ignoring that steel softens and bends in heat is silly. it does,

It should be, if you continually ignore the fact that the material is never allowed to get to its critical weakening temperature in such products because it is being continually cooled in air.
Steel cannot be melted in a forge.
What is risible is that you write this when the evidence is before you.

I don't think those are wooden lifeboats. Corrugated steel had been used to lifeboats for quite some time before that that looks similar to the lapping used in wooden boats. Here's an example: http://amhistory.si.edu/onthewater/collection/AF_1645(14).html
These are probably the Francis Life Car brand of lifeboat: [url]http://amhistory.si.edu/onthewater/assets/object/full/2009-5587.jpg[/URL]
I don't think there's much chance they're made of word, since wood does not distort like that under heat.

Yeah, fair point. I agree that these look like steel life boats.

I always enjoy
So... why do we fireproof the steel girders?
That's the question that always go unanswered and ends this conversation.

Given the myriad of examples of partial collapses due to fire alone it is cognitive dissonance to then claim that fire cannot ever overcome the ability of steel to carry a load.
