Your points about the verinage and jolt, etc, is a good one. But even there, my understanding of verinage and jolt, etc, relies on floor to floor contact being the only possible way of supplying any kind of jolt, since the verinage technique relies on pulling the columns out of alignment, which of course means that column to column contact couldn't be a contributor.
Which of course means that if we discard the obvious lunacy of hiding these hydraulics, etc, and take it at face value, then the columns at the WTC CAN'T contribute to any kind of "jolt" since like in verified verinage demo, the columns would ALSO be out of alignment.
Also, verinage as far as I know has only been applied to concrete-framed structures. They behave quite a bit differently, and the bearing surfaces between the descending and lower portions are much larger.
I haven't done an exhaustive survey of the technique, so feel free to correct me.
