You are leaving out the significant fact that the horizontal support braces were designed to hold up only the one floor, and were rated to hold up only that one floor's worth of weight. It wasn't holding up the one floor's worth of weight plus the weight of all the floors above it, the way most other buildings are designed and the way the doubting Thomases incorrectly believe they were.
Once the floors began to fall, the stress would have been transferred to the vertical support columns in the core and on the exterior walls horizontally, rather than vertically.

No, becuase every video of the collapse in existence shows that the structural failure begain up at the ninety-somethingth floor, where the aircraft hit, and proceeded downward in a chain reaction. It didn't start down in the underground parking lot.
Thus, whichever scenario actually happened, it necessarily has to take into account that it had to have happened at the location where the aircraft crashed into the buildings.

Much more likely than three towers falling for the first time ever on the
same day due to fire.
So you agree that after :06 and 23 degrees, the hinge 'snaps' and the
top section begins to come down toward Earth at this point.
It would follow that the West wall of the upper section (the side previously
hinged) should remain at a constant length as the upper block crushes
the remainder of the tower.
note: this side of the tower had no "drop distance" and therefore did not
slam into any lower section of the tower.
Do you agree with this fact of physics and as required by your hinge theory?

Edit: Can someone provide us with a link where the molten materials "were explained time and again?"
Not only does it [iron] burn/oxidize, but it can burn/oxidize at low temperatures.

Bait and switch. I was discussing how the floors fell. I wasn't discussing what happened to the support columns as yet.
No, it's not clear, unless you are suggesting the floors held up the columns and not the other way around. How would a failed connection from the floor to the column break the column?
For that, you haven't been reading ExilAxis' posts. He posted...or at least, I believe he was the one who posted it, I'll need to double check... a quite beautiful photo of one of the support girders that shows it had been bent over in a ghastly angle before tearing like a piece of paper. NOT cut, NOT melted, but TORN. It's clear that as the floors fell the columns were being pushed/pulled sideways by their connections to the floors and they were literally torn and/or broken to pieces.
Thus, I do not have to tell you that whatever vertical structural strength the columns may have had, it was negated once the forces of the collapse began pushing and pulling them horizontally.

Sorry I missed this.
Have you observed the DSC curve for this, "sawdust"?
Just wondering if you noticed the temperature scale and energy release
per gram?
Did you also notice the control sample of superthermite which was tested
under the same conditions?
A simple, "yes", or "no" answer will suffice.
Thanks.

That pesky core structure can't be explained away so let's just ignore it.
