Ok cool.... he's a liar.
So.... can we talk about what I'm actualy trying to findout?
Here's another thing I need clarification on. If every floor did way 6,818 tons, the 18 floors in tower one that came down would weigh 122,724 tons, or 245,448,000 Lbs. (way over exaggerated) if it fell straight down onto the 14,974,480 sq. inch 91st floor, that would be a load of 49.34 psi, and it would be dispersed over 32, 36,000 psi floor trusses, a 52,000 psi inner core, and a 23,000 psi outer skin.
How much resistance in psi would the falling 18 floors encounter if you were to add up all the yield strength of the steels entire surface area affected?
Meaning, how much force would it take to smash 32, 18'L 12"H X32"W X.25 I beams rated for 36,00o psi? Or the 52 x 22 inch thick center column rated at 52,000 psi? Also the 236 columns rated at 23,000 psi each, that made up the walls on each and ever floor?
In my example, the 245,448,000 Lbs. of the 18 falling floors would equal would equal 111,333,340 kg. Ill take the overall height of 415 meter / 110 floors to get a ball park story of 3.77 meters, or about 12.4 Ft. per story. Energy at impact: 4101 joules, or 21 psi. after an 12.4 foot drop. Add the impact to the weight of the structure falling 49.34 + 12.40= 61.74 Psi. spread out over the 14,974,480 sq. inch 91st floor. So..... no collapse.
