Sander you do tend to wander all over the place - in this one completely changing the subject of discussion.Ozzie,
I know what happened and that heat made it collapse. My problem has been my inability to understand / visualize the column failure(s). I've seen no examples of those failed columns save that one bent into a horseshoe. I read the NIST assertion of beam expansion... but I thought the col 79 was supposedly a buckling from loss of bracing... But a single floor collapse leading that that column buckling seems counter intuitive to me.
We (as in you and I) were discussing issues with T Szamboti's "Missing Jolt" which is definitely a WTC Twin Towers - WTC1 and WTC2 - issue and focussed on WTC1.
You start your post continuing our MJ Twin Towers discussion THEN manage to change to WTC7 without pausing for breath. And everyone goes along with you.
Except me.
I'm aware of that - no need to keep repeating unless there is a risk of misunderstanding.I don't see anything to support CD...
Believe me I fully comprehend your difficulty. (And I'm assuming from the "it" and "these towers" you are back discussing the Twin towers.) That is why I have spent effort posting explanations. I have not dismissed you with suggestions that you read NIST - whether for WTC1/WTC2 OR WTC7. That will not help your comprehension - especially when you have many times expressed your doubts about NIST. You are looking for explanations but you do not come to grips with the explanations that have been posted, repeated, amplified and - on request - clarified.but I am having a hard time understanding how it goes from lots of heat to the whole thing collapsing. What I an saying is... even if it is not precisely what happened... I want to be able to "see" / conceptualize in slo mo in my mind... how these towers started to become undone. I don't expect anyone to do a gif or vid of it.....
Well you have a big barrier and comprehension problem because column buckling was the dominant component of the cascade failure for "initiation stage" for each of the Twins.and "column" buckling is not doing it for me. Sorry
And if you do not read or cannot process explanations and don't follow up the bits of misunderstanding by seeking more explanation - there is little I or anyone else who is prepared to explain can do to help you.

) areas where - to avoid confusion - we will need to define what scenario or stage of collapse we are actually discussing. I'll give the short and easy answers by
