Oh wow! That is so fucking informative.

Nothing about the floor slab in the core being different from the floor slab outside the core.

Nothing about mechanical floors.

How much concrete was in the 6 basement levels? In 20 years I have not seen a single source specify steel and concrete below ground level versus steel and concrete above ground level.

It is as though BELIEVERS need to defend their minds from relevant information. Thinking must be prevented at all costs.

Are you saying that the $20,000,000 NCSTAR1 report should not specify the total amount of concrete even though it specifies the total amount of steel three times?

With a mass of about 500,000 tons (5 x 108 kilograms), a height of about 1,350 ft. (411 meters), and the acceleration of gravity at 9.8 meters per second 2, he came up with a potential energy total of 1019 ergs (1012 Joules or 278 Megawatt-hours). "That's about 1 percent of the energy released by a small atomic bomb," .

The funny thing about a potential energy calculation is that it assumes that the mass in question is falling through empty space and that gravity is free to accelerate the mass all of the way. Then there is the matter of skyscrapers being bottom heavy. Oh, the article doesn't mention that.
