In your earlier posted image it would be above th "s" in "somebody" in your lower notation. Notice it is tapered. Notice the vertical lines in it from form boards.

But Chris, that's not 17 feet thick. :confused: And if the rebar is 3" thick, how thick is the handrail on the stairs? :confused: (Think carefully. I know the answer.) How do you explain these discrepancies, and what do you suppose happened to all the rest of the concrete? :confused: The section in question alone would have hundreds of tons of concrete, according to you. Where did it all go, and how did it disappear without damaging the interior? :confused:

For the love of all construction workers, they don't make 3" diameter rebar!

As if there was nothing custom and special about the WTC towers.

Correct, the edge of the concrete in your image is the perpindicuarly opposite wall which was, I believe, a max of 12 feet thick on WTC 2.

With the rest of your questions ou refer to the other image, I think.

Where's your source for the 3"? Which steel company had the contract to manufacture it?

In fact, which construction companys worked on the WTC. Who were the workers there? How many of them remember using concrete for the core? How many of them have you talked to?

What is your "belief" based on?

And what would be the thickness of the short side in tower 1, which is what we're talking about?

And seriously, how thick is the stair handrail if that's 3" rebar? You don't have to be exact. Just take a guess.

And PLEASE answer my question about where all the concrete went, and how it all went away without destroying interior elements like stairs. I mean, how can there be a clean "end" of a concrete wall that supposedly disintegrated?

A week away and nothing new. Proof shown to chris again and again (which he ignores or denies the existance of despite it's obvious nature), and all he has is the same old misinterpreted pictures that were debunked (his interpretation of them I mean) long ago on this very thread. Chris has also yet to explain why he lied on the other site.

The documentary stated 3" inch over and over because of the difficulty of the butt weld re-occuring every 40 feet with bars on 4 foot centers. Now that I'm thinking about it, I feel as though a thicker bar was mentioned for the core base wall.

I use the word "feel" because I realize that that in the image I post of the base, that the coiled bar over the concrete wall does look larger than 3". There was a part of the documentary which slowed down as the construction process slowed around all the prep for getting the core off the gronud properly, mostly the elevator alignment process but also the start of myriad conduit/plumbing inside the core.

That part showed a network of very heavy reinforcing bar and mentioned that the bar couldn't be bent because it was so large and had to be welded to go around corners. That was right at ground level and I had not remembered until now. Meaning the coiled bar on top of the concrete core wall could be transitionary bar with a size approaching 6 inch.

One thing for certain that has not changed; the tight coils are totally a chracteristic of high tensile steel subjected to extreme stresses.

Mr Brown,

Are you familiar with the Black Knight scene from "Monty Python And The Holy Grail"?

If you are not, let me recap briefly. King Arthur comes across a Black Knight who will not let him pass. They fight, and the king successfully removes one of the Knight's arms. The Black Knight, however, ignores the wound and continues to fight. So Arthur chops the other off. Still the Black Knight will not surrender. Ultimately King Arthur also chops off both the knight's legs. As Arthur rides away the Black Knight still refuses to surrender.

John Cleese revealed that the story was inspired by a teacher of his. The teacher told a tale of two Greek wrestlers, locked in an epic struggle. They remained locked together for day after day, until at last one of the wrestlers gave up in utter exhaustion, unable to take any more.

The two wrestlers were pulled apart, but when the victorious wrestler was approached it was discovered he was dead.

The moral of the story was "If you don't give up you can't possibly lose". Cleese wrote the Black Knight scene in tribute to how ridiculous that notion was.

I believe the above tale has some bearing on this current discussion. Do you?

That's quite a specific memory! Or were you taking notes? And the name of the documentary? Surely you remember that?
 
Maybe I missed out on this part of the conversation...why is 3" rebar important? I'm not reading through 67 pages of posts.

Chris, not to be mean but "I saw it in a documentary" isn't evidence unless you know the name of the documentary in question. Once that is straighted out, then maybe we can see for ourselves.

What do you think I am? Can I expect you to remember that kind of details from a documentary you saw 16 years ago?

I remember the concrete core from the documentary. Others remember it from documentaries made from the same film footage.

I spoke to a 64 year old steel worker that worked on both towers. He didn't remember the concrete core, but the elevators entrances and exits were sheathed in plywood for safety. After awhile of talking about it, he said, "Okay, that must have been where the concrete was pumped up." probably referring to the mud for the floors. Also, there was only a very short period of time when the exterior of the core was exposed for him and he was passing by it between the advancing floors and the forming or stripping of forms. Probably only one floor. And, because he was working always on the top he would exit the elevators sheathed in plywood from the concrete core, walk around to the stairs going up through the floors at various stages of completion, passing either an open space in the core, no forms in place yet, or, an inner steel form in place, or the exterior form wood in place. So he didn't have much opportunity to see the concrete walls.

yes, I will tell you all about it. The documentary was called "The Construction Of The Twin Towers."

The big slowdown in the constructon documented by the video was the concrete core. Specifically the butt weld occuring every 40 feet in the special high tensile steel rebar used in the cast concrete core. Only welders with a security clearance were allowed to make the weld.

Of course not. That would be impossible.

The Library of Congress, the New York Public Library, the Brooklyn Public Library, Google, and Mark Roberts have not heard of this 'documentary."

Guess again, Chris.

It's also not on IMDB. And EVERYTHING is on IMDB.

Neither has IMDB or Netflix or Blockbuster.

I have my Tivo set to show me everything twin towers or world trade center related. It has never shown up (even with the 5 year anniversary coming up and everything else is being run over and over.)
