1. Robertson/Jones audio states clearly that the structure was "core columns and perimeter columns" (~18:00-19:00). Thanks! <this question was resolved. only steel columns were "structure">

a. Newsweek was clearly wrong, unless they misinterpreted the fireproof "shaftwalls" as concrete.
b. We can resolve this with a quick email to Mr. Robertson. That would either confirm or end the "disappearing concrete wall" conspiracy. Just ask him if the core had structural concrete walls or not.
c. The conspiracy would need better proof of concrete walls than a misprint in Newsweek.
d. You need to show the remnants of wall on the ground, there would be 12 miles of wall that you don't see lying on the ground.
e. I provided several independent sources that show the towers did not have concrete core
walls. (FEMA, NIST, Robertson, Guardian, and photos that don't show R/C walls on the ground) You need to show several sources of the reinforced concrete walls at least 3' thick on drawings and on the ground. You never show any concrete wall pieces on the ground.
2. Fire would never be a cause of collapse in a tower with a concrete structural core. Dumbed down and divided America is expected to accept steel core columns because of cognitive distortions used in presentation. There was fire, steel does bend when it is heated. We know how dumb the perps want Americans to be and assist them to assume that small fires on a few floors could heat the entire steel structure as if Allahs great torch from hell came from the ground and raised it all uniformly to that temperature at one moment to cause a free fall collapse. No way, even in hell.
I provided a link, from "The Guardian" which is very neutral source of information, as well as from other credible sources. No mention of concrete walls.
Then you need to define what possible gain the "conspiracy" could have from lying about the concrete walls: One guardian article should equal one Newsweek misprint. As for the "small fire" did you see the fireball at impact? There were hundreds of thousands of gallons of jet fuel in the jets that created massive fire, plus the jet impact knocked the fireproofing off the steel. so you have a massive fire and no fireproofing, the towers collapsed exactly as predicted by the NIST engineers.
Plus, part-B of the question:
what possible gain would a conspiracy have to say that there were or were not concrete walls? The conspiracy makes no sense, just ask Mr. Robertson.
3. This thread is not about what brought the towers down, it is about what was brought down, the towers themselves. The towers survived 110mph winds, and they were designed for 120mph, while probably capable of surviving 140mph because the method of construction was so good. The concrete tubular core kept the steel perfectly aligned in its maximum load bearing position. The hat truss was bearing on the top of the concrete tube which absolutely made the moment frames and transfer of sway into compression loads optimized. Moment frames and that transfer with that mechanism do not work well all in the same material because that which is trying to resist the flex, flexes as much as that which it is trying to brace and stiffen. The core resisted torsion supremely, so oscillation was gone.
3. So you agree that there was no "secret method of mass murder" , correct ? If not, you need to say what it was.
4. You continually fail to describe the conspiracy. Who all was supposedly involved? You get no credit for saying Rudy did it....(thats an LOL actually)
The towers were built way before Rudy came to NY. He had nothing to gain from the tower design. Even Silverstein had nothing to gain/lose. The buildings were insured. The insurance companies would be all over any "wall conspiracy". The Port Authority also has all the tower design info, so you need to see that there were way too many people involved to cover anything up.
who would gain anything from disappearing concrete walls? No one Its a stupid conspiracy, really dumb.
5. They were also fine until the sunlight of September 11, 2001 hit them. Off topic herr kaiser.
5. what difference would it make if there was a concrete core or not? If the buildings stood for ~35-years, however they were built was fine.
the "question is: what difference did it make if it had concrete walls or not? The towers didn't just "fall down" from bad design. The designs were reviewed by NIST and ASCE and many others who all said that the buildings, w/o concrete walls, fell exactly as engineers would expect.
If the jets didn't hit them the design was fine. I don't see where the "wall conspiracy" came from, its just stupidity.
6. Are you competing with divot for how much BS you can assert? Not a question herr kaiser.
6. I can provide the equations (mathematical proof) for the deflection of the WTC tower if you have any way of verifying them.
Do you want me to post equations for the wind load and deflection with and w/o concrete walls? <thats an on-topic question>
If I prove mathematically that the concrete couldn't possibly deflect 12' will you admit that there were no concrete walls, as everyone but you acknowledges?
Its engineering proof that the documented sway the towers experienced could not happen if concrete walls were present. Steel columns sway, concrete core walls don't. Thats engineering, not bullshit. Your conspiracy is bullshit.
