Albert Doyle Wrote:The hypothesis should be correlated with the actual conditions of the collapse. If a full floor of core columns were magically removed the inner floor pad would drop pulling the fastened connections with the outer frame inward ripping the outer frame supports inward and out of line with those below them.The correct formula here, that is more in line with the actual event, is the entire section above would then become a downward pile driver initiating the floor pad collapse. This is probably very close to what actually happened. This would be aided by a damaged core and frame steel weakened by fires.
Only 1/3rd of perimeter columns were spliced on any given floor. So your hypothesis is incorrect.
Quote: What Tony said were demolition plumes were actually air pressure plumes from the collapsing floors. A sharp eye could see they couldn't be from explosives in the core because the source was too close to the wall they were blasting out of. There were no detonation flashes from those plumes, their source was definitely pneumatic.You can't seriously believe the focused jets we see emanating from the building are from pressure due to floor collapses. Logically that pressure would be spread over a wide area.
