NIST, the building's structure was a typical tube-frame design, with columns in the core and on the perimeter, and lateral loads resisted by perimeter moment frames

Just curious eots. Can you explain why you put "NIST" atthe start of that cherry-picked quote above? I clicked the reference notation after that sentence and it refers to a document written by John J. Salvarinas. I searched that document for the word "tube" and couldn't find it anywhere within.
What gives eots? Lying through your ass again?
I looked through NIST's publications for WTC7, NCSTAR 1A, NCSTAR 1-9, and NCSTAR 1-9A and couldn't find the word "tube in those either.
So where did NIST say this? Here is the link to Salvarinas' document. See if you can find the statement, referenced by your link, that says "typical tube design"...
