However, despite your notions of floors turning into Landkreuzer tanks as they break free, in reality such a process results in a tangled mess of columns and beams and everything else pushing on each other, and hence limits how quickly and completely such an "avalanche" can destroy a building, as seen in the simulations I've linked previously.
Jeffrey Orling Wrote:But your call for a repeatable experiments is a straw man argument.No, a straw man argument is when one ignores another's argument and constructs a misrepresentation of it to refute instead. My call for for experiments is an appeal to the scientific method, a methodology which would have kept Bazant's nonsense out of the Journal of Engerneering Mechanics had it been respected, and which I'm quite sure your notions of what happened to the towers could never pass the test of either.
Jeffrey Orlng Wrote:Was it you who played with models trying to simulate the collapse?No, that was psikeyhackr. Were I to invest the effort into constructing a model of how the towers came down, either a scaled down physical model or a full scale computer simulation; it would be rigged with explosives all the way down, as I've no doubt that's what it took took for them to come down as quickly and completely as they did.
