2- so you're using statements for the towers and using it here? And here I was, thinking that engineers had a little more integrity about making these kinds of statements. Guess I was wrong. NIST predicts a significant amount of heat in the lower floor beams too. Maybe you need to quit ignoring that and factor that little tidbit in before you make sweeping statements about how many falling floors it would take.
3- Yep. Never used for demolition of a building. Proven.

1-I was clearly talking about a lateral displacement of the connections, and you give me lateral displacement of the building.
Really, this is to be expected from you though. Getting a straight answer outta you can be like squeezing blood out of a turnip. Why you do this is unfathomable. Actually, it is, would be a violation of T&C to explain it.
2- Yes. Walk-off is when it is pushed off its bearing seat. The bolts aren't there to hold the weight. Only to keep it aligned. I didn't know that buildings in NYC were designed for extreme earthquakes. Or are you making another non-relevant point here... as usual.
3- 1 end of the floor beam (that underwent thermal expansion) butted into the external columns. the other acted on the girder. So you saying that 2" on each end is demonstrably false. the girder will be weaker in resisting lateral forces (weak beam) than the ext column. So all 4" will act against the girder.
4- no idea. But you're also ignoring that the floors below were heated, which would weaken them. Also, you're comparing it to a statement that NIST made regarding a perfectly intact truss and applying that here, when the conditions inside 7 clearly weren't pristine. Again, not surprising...

New York City is not free from earthquakes. It is located in a zone of moderate seismicity. For instance,
since 1884 the entire state of New York has experienced four damaging earthquakes with magnitudes
between about M~5 and M~5.5 and many smaller earthquakes are recorded every year. The greater New
York City area alone can expect on average one magnitude M~5 earthquake about once every 100 to 200
years (the last such damaging event with magnitude M~5.2 occurred in 1884). Based on geological
arguments and comparison to geologically similar regions elsewhere, the possibility cannot be excluded
that magnitudes as high as M~7 may occur near New York City, including adjacent offshore areas on the
Atlantic coastal shelf. This possibility for M > 6 earthquakes exists despite the fact that in the short
historic record (about 300 years), no larger earthquakes than M=5.2 have been observed near New York
City. But during historic time much larger (M = 7 ± .5) and quite damaging events have occurred
elsewhere along the Atlantic coast of eastern North America.
The ground motions associated with earthquakes in the eastern United States differ distinctly from ground
motions in the western U.S. in several important ways. Eastern earthquakes are reported to have released
higher rock stresses compared to their western counterparts, thereby causing the ground motions to
contain more high-frequency energy. The ground motion shaking is more intensely felt to larger distances
because the Earth’s crust and its rocks in the eastern U.S. transmit seismic waves more efficiently,
especially at the higher frequencies of engineering interest. This stronger shaking, especially at shorter
building periods and to larger distances, is caused by the fact that the crustal rocks in the eastern U.S. tend
to be older, more competent, and less riddled with seismically active faults, compared to generally
younger California rocks along the tectonically very active San Andreas fault system.

Well, since fire has only partially collapsed buildings in steel skyscrappers over the past 100 years or so, my guess would be partial collapses in each building looking very different from one another. But hey, that's just my logic talking to me.
Your "logic" seems to tell you that anything is possible as long as it is explained to you by authoritarian types. And of course your "logic" is correct because there was just too much dam destruction and energy from them to be demo'd, had to just be the fires.
...because it's clear you like fantasy more than reason...

To me, yes it is more logical that 2 planes crashed into 2 110 story buildings causing extreme damage and fires that toppled one of them onto a 47 story building damaging it and causing unfought fires that raged for hours and managed to weaken it's structure enough for it to eventually collapse. A first? Yes. Illogical, hardly.

and since we all know that there is not 1 solid single shred of physical evidence proving any of the conspiracy theories

Can't you see the absurdity of what you're saying?

I don't need any possibilities explained to me, and I'm not the one putting forth absolutes such as "This can't be, it's never happened before!!!! ZOMG!@!@!1111oneone!!! INSIDE JOB!"
Ultima said there was no "official reports", well, mystery solved.

So since "we" have never experienced a total global collapse due to fire we should just assume it was, indeed, just the fire that caused the collapses???
Originally posted by mirageofdeceit
...but what do those official reports state??
I have partially read them, but I can't say I can take them too seriously because they're flawed.
There's a first time for everything, period.
