(1,464 posts)As the upper block nibbles away the lower, the lower nibbles away the upper. There is no debris mat.
Dr. Bazant's theory rears no resemblance to reality. There is no evidence of a pristine top "block" riding a debris mat down to the ground, pulverizing all the floors in the way. No photos. No photo evidence from the debris pile. The notion is refuted by the persistence of the lower core, and by the fact that the upper block on WTC1 was visibly coming apart before the structure under the impact zone failed. Dr. Bazant's theory is thus discredited.
Dr. Bazant's "limiting case" assumes MAXIMAL transmission of kinetic energy to the structure. It ignores all the energy requirements of pulverizing the floors. breaking connections, twisting and crushing the steel.
I never said the collapse has to be halted. That's a straw man argument. But I've never seen anyone do an energy budget that accounts for all the energy sinks (pulverizing the floors. breaking connections, twisting and crushing the steel) at all, let alone one that explains the speed of the collapses. Instead, NIST simply dodges the issue.
