I'm talking about NIST who claims that the jet fuel all burned up in 10-20 minutes but the building still stood at that point.
Now pile up some office furniture under some steel beams the size of what was used in the WTC, with the same heat conducting capacity as the WTC, set it on fire, use some jet fuel if you like to ignite, and let's see that fail enough in an hour enough to collapse an entire 110 story steel structured high rise. Then we're talking.
You're not "talking". You're showing your ignorance.
What makes you think that a "office contents" fire is going to be any cooler than a "jet fuel" fire?
There is no reason whatsoever to use pieces "as big as the WTC". There's no particular reason to use any particular fuel.
There is this thing called "stress". It is load per unit area. It is the determinant of how ALL steel is going to behave, no matter what sized component it is a part of.
If you get the stress levels correct, if you get the temperatures correct, then you can demonstrate what a WTC sized core column will do with a 2" square x 3' long x 0.06 wall thickness piece of extruded steel tubing.
Of course, doing it right (i.e., properly scaling the loads, moments, etc) will get a bunch of ignorant kids whining that "you're cheating on the tests...".
The thing that they may have done differently was to demonstrate the "safety margin" in the load that was used. Perhaps they should have taken 2 beams, loaded one until it failed, and then loaded the second beam with, say 1/3rd that weight. And then heated it.
Not perfect, but better.
BTW, I've got a question for you. Your suggestion that size made a difference is pertinent (if you don't know how to compensate properly) in the thermodynamics of heating of the beam. Note that the beam failed in about 4 minutes (IIRC). Heat wicking is a consideration.
But tell me something. Suppose the, say, 97th, 98th & 99th floors of the towers are on fire, and their burning contents are heating up their support columns. Where is the heat in the 98th floor going to "wick to", with the 97th & 99th floors also on fire?
How many floors have to collapse for the entire structure to collapse?

PS. Aw cripes.
As soon as I ask him to provide some answers, he goes & gets suspended...
Any of you other truthers want to take a shot at this?
