i only read the first sentence so ill correct the flaw i found
steel reinforcement = rebar
steel girder = HUGE beam of steel
which one is stonger?
edit: upon further inspection it seems yet again your talking about something that we arent...
"I'm sorry... I thought the argument was that normal fire doesn't make steel reinforced buildings collapse."
no...
buildings that are made completely out of steel.... not steel reinforced concrete... there is a HUGE difference...
ill state my fact again....
not 1 STEEL (not steel reinforced) building has collapsed due to fire before OR since 9/11
Well... I was actually talking about ND's claim, which appears to be different than yours... but none the less, you can play too.
1. WTC 1, 2, and 7 were not made completely of steel. The claim to this point was actually that "steel structures do not collapse because of fire". The argument has been, for years now, that "normal fires" could not have been hot enough to cause failure in the steel because of the properties of the metal itself. I have demonstrated in several ways now that it could.
That is why ND is now clinging to asbestos. Because I have demonstrated that "normal" fires DO and HAVE caused structural failure in structural steel. That is the argument I had to first win (several times now) to move forward.
The building fires which collapsed were supported by big assed steel beams, which failed due to "normal fire" alone.
WTC 1 and WTC 2 never failed due to normal fire before. That is an accurate statement. The buildings were unique, and drawing comparisons to other buildings when it suits you, and claiming that they "weren't like" them when it doesn't is a rat race we can run all day.
McCormick was a steel structure, thought to be "fireproof". It was not.
WTC 1&2 was a tube design. Steel in the middle, steel on the outside, with long girders connecting them in order to maximize office space. It is unique in this way.
I have demonstrated that "normal fire" causes failure in steel. Every example I give will be different than WTC. Every example you give will be different than WTC. So it is important that we agree, if nothing else, on fundamentals... or we can have nothing to debate... only run in circles we think mimic the circumstances, on either side of them.
I defeated this argument with the bridge.
Normal fire causes structural failure to HUGE structural steel beams.
I did not address fireproofing, or sprinklers, or gravity, or fireproof passports. Just this one, simple, clearly exampled piece of information... and have been defending the obvious for 20 some pages now.
We must agree on fundamentals. I will ask 3 questions.
1. Did this happen as reported, yes or no?
2. What is the temperature of an open air gasoline fire?
3. If steel is "normal fire" proof, why do building codes mandate that they be coated with fireproofing?
I am not asking you to determine the validity of my questions. I am simply asking for them to be answered. Please answer these questions in your replies attacking me, my integrity, and my intelligence... just try to work them in.
