Look at what the NIST studies are actually studying: in the first case the effects of damage to the fireproofing on the steel and in the second measuring data points for validation of the collapse modelling. Neither is saying anything about fire alone causing collapse or the maximum temperatures actually reached in the fires.
I do not see that makes any difference to the facts. Fact: WTC floor models did not collapse when heated to 700
oC. Fact: 157 out of 160 steel samples taken from the collapse initiation zone saw no temperature greater than 250
oC.

You still completely miss the point the I and Pericynthion have been trying to make for most of this thread: load re-distribution due to structural damage makes the structure vulnerable to further damage due to fire.
I am not sure what all the “I and Pericynthion” talk is about. Pericynthion has only made 3 posts in this whole thread and disappears when his theory is questioned.
I agree, load re-distribution and fire may weaken a structure… but they do not make high rise steel framed buildings imitate a controlled demolition, collapsing totally and virtually symmetrically at freefall speed.

The fire does not have to reach any specific temperature for this to be true, the remaining elements of a damaged structure can be carrying loads very close to their ultimate, so a small reduction in strength due to heating can be enough to cause fauilure.
So you believe 100
oC fires progressively moving through a building would be enough to cause a complete collapse so long as a single structural column had initially been removed? For this to be true, you would have to believe that WTC7 was teetering on the edge of a collapse as soon as the light debris from WTC1 had struck.
Here is a totally theoretical question for you flyingswan but put yourself in the position and answer it seriously – if you personally were given the means to make a cut through any 2 structural columns in a building the size and design of WTC7, then given enough hydrocarbon fuels to light fires around all of the remaining columns, do you seriously believe you could cause a collapse as seen on 9/11?

Up to now, you have been arguing that it was a CD because it looked like one. I produce a list of points showing how it differed from a CD and you come back with this preposterous slow-motion CD theory, unlike any real CD, with the explosions spread over hours to mimic a collapse due to damage and fire. As I said, your beliefs are immune to evidence.
It is not slow-motion but spread over a period so as not to make the controlled demolition obvious. The only preposterous thing I see is that you believe fire can cause this collapse over a period of time but explosives/thermite cannot achieve the same thing.
You did not produce a list of points showing how the collapse differed from controlled demolition at all. You came up with one single good point of where it differs and that was the lack of audible explosions immediately prior to the collapse as seen with other controlled demolitions.
Now suppose for a moment you are in charge of creating a strategy to bring down a building without anyone knowing it is a controlled demolition. Are you going to make the setup identical to a conventional controlled demolition, complete with a string of explosions immediately prior to the collapse? Answer: No.

I am not claiming that such temperatures are necessary for a collapse, though with the quantities of diesel fuel in the building there may well have been.
No,
I am claiming such temperatures are necessary. These 1,000
oC+ temperatures would be required to heat the structural steel columns to a point where they lost enough strength to collapse. Also these temperatures during the fire are the only way to explain the 727
oC debris pile of WTC7 shown in
NASA images taken 5 days after the collapse.

You keep bringing up these Mossad agents, but you have signally failed to explain what you think they were doing with their explosives. If they were part of the CD operation, why weren't the explosives already in the buildings?
When you build a house, do you order to site only the exact number of bricks needed? When you have painted your walls, do you have paint leftover? When you carpet your floors, do you have any cut offs? When tiling your bathroom, do you have spare tiles? Could
that perhaps be why every last explosive the Mossad agents were found in possession of was not in the buildings?
Failed to explain what I think they were doing? Let us see, Twin Towers exhibiting characteristics of a controlled demolition, Mossad agents celebrating the collapse, Mossad agents arrested with van of explosives… oh I just cannot figure it out so hmm yes, I think they were on holiday.
The acting dumb thing over this is not working for me flyingswan, so either
