While I find your model impressive , in that you actually took the time and effort to construct it , I must also say that it in no way represents the construction of the towers .
Your paper/cardboard has a diameter that is larger than the diameter of the holes in the center of your steel rings ., which is not representative of the WTC construction .
Nice try tho , I'll give you that much .
If you would do as I've suggested , time and time again , and study the construction of the towers , you would come to the glaringly obvious understanding that the floors DID NOT support the floors above them .

In order to arrive at a fairly accurate estimate , you would need to know what mix-design was used in the concrete , how much entrained air it contained and what the unit weight of the concrete was .
As well as supposing that the mix design etc., was strictly adhered to all the way to the top of the tower .
From experience , I know this is not always the case . There will be times that you don't have the desired slump , so water is either added or subtracted from the mix , as well as the entrained air either added to or subtracted from the batch .
Concrete mixing is never an exact science , therefore I say it is possible to ascertain only a ballpark guesstimate of the weight .
Do you have me confused with another poster ? I never gave you a 'number' , so , how do you conclude that my 'number' is 30% too heavy ?
But the STRANGE THING IS that we haven't been told a number for the weight of the entire floor assembly. I haven't seen it mentioned anywhere in more than 3 years. This incident is approaching NINE YEARS. They have been talking about these floor assemblies either pancaking or not pancaking for ages. It is the total weight that matters because the way the upper knuckles were embedded into the concrete they could not be separated. I encourage you to find the total weight or even the weight of the concrete slab specified anywhere.

Have you ever consider going to the NIST website, looking at the extensive records of the design critieria, including the FLOOR DEAD LOADS, and maybe doing the calculations for yourself? And have you possibly considered the alternatvie - that you are just plain dead wrong about needing to know the "total weight" in order to compile the failure analysis?
But what does this say about all of the BRILLIANT PEOPLE claiming to know physics who have been discussing this subject for years? Why hasn't it been mentioned A LOT. and therefore easy to find?
