Coffee spillage alert!!

Cole didn't attempt to replicate Bazant's theoretical model with a physical model, and he didn't, so it is practically impossible that his experiment would falsify or verify Bazant's results.
However, Cole's model is essentially of the type to which Bazant's crush-down-crush-up mechanism
would apply - one, where column crushing under vertical axial impact would be the dominating failure mode. So how come Cole doesn't verify Bazant? Because, I must tell you once more, he scaled it wrong! Bazant has column capacity restricted to values that are plausibly within the range of the actual WTC columns, while Cole's vertical supports are ridiculously strong and outside of that envelope.
However, the reason Bazant is wrong is not that a model, or building, collapsing according to his model would behave differently than he predicts, but because he doesn't model the actual WTC. He thus commits an error similar to one of the several errors Cole commits. You see, vertical column crushing simply is not the thing that actually happened (significantly) at the 3D-reality of the WTC, where columns were mostly bypassed once collapse was underway; they subsequently simply fell to the side, having become laterally unsupported.
So Cole actually fails to falsify the reality of a gravity collase of the Twins, and separately he fails to model the wrong Bazant model correctly, as he fails to scale correctly.
