Explanation if really needed BUT it is observed fact that the global collapse occurred without end for end loading the outer tube columns to failure....Tony, I apologize for jumping in here but I have a few comments on this.
How can the exterior columns be bypassed?...
Which did not happen. So you are describing some fantasy collapse mechanism. Not the mechanism which occurred with WTC1 and WTC2 on 9/11. The outer columns peeled off essentially undamaged other than for the shearing of the floor connectors...... If the building is coming straight down the exterior columns of the upper part are crushing the exterior columns of the lower part and likewise the core columns of the upper part are crushing the core columns of the lower part....
I fully understand why you need this claim to support your fantasy. Only problem is it didn't happen. Hence the multiple times I have asked "which columns are being crushed?" or equivalent.. BTW don't despair - even the good guys get this one wrong.... Columns crushing columns precludes free fall at any time....
...which buckling columns. I'll even shortcut it for you. "Which proportion of the core columns do you claim buckled"....Dave's answer does not address the resistance of the buckling columns.
