Christophera, you do realize that there was a huge amount of concrete that went into the WTC, right? You see, it wasn't only the floor slabs that were made of concrete at the WTC. And it sure wasn't your core. (Your core was made of invisicrete, remember. Or was it 3" mirrorcrete on 4' invisicrete centers? I forget which.) There was one other thing, a huge thing, which was also made of concrete.
How accurate is your recollection of the documentary? As you admitted yourself, one cannot expect to remember the details from a documentary one has seen 16 years ago. Was the only footage of "your" concrete core shown at the base of the towers? Just as they were starting to get built? Just as the towers were "getting off the gronud properly"? Down at the base? At or even under the street level?
Are you sure your memory didn't mix up the concrete "core" with the concrete retaining wall? The huge thing that was constructed around the whole WTC complex to keep the ground water at bay? The huge thing that was, in fact, made of concrete? Which was, in fact, reinforced with metal? And, just as you say, the construction of this sealed concrete "tub" did slow down the construction process, since it had to be completed before the construction of the buildings themselves could begin. I'm not a structural engineer nor even a construction worker, but I guess it's hard to erect a building before its foundations are completed.
And there actually is a documentary from about 16 years ago. Well, 23 actually, it was apparently made in 83. It speaks of concrete. Your only problem is, the concrete didn't go in the core, it went into the retaining wall and the foundations. And it shows how the metal reinforcement cages were used in the retaining wall construction. It shows how the retaining wall had to be reinforced with rather large steel tendons, anchored into the bedrock. I guess those might be 3" thick.
IIRC, the documentary was also mentioned somewhere in this very thread. Remove excess spaces.

Since all your claims about the core from the ellusive documentary are also consistent with the retaining wall around the WTC, IMO, the whole thing can be explained by your faulty and selective memory. Convince me of your side of the story. Provide your documentary. Provide your version of WTC floor plans with concrete core included. Where were the elevators, various steel columns, concrete walls and hallways? Why is it so hard to provide a simple bird's eye view of your version of Towers? Modify one of FEMA/NIST drawings, modify Kevin's layout or draw a large square and in it a smaller rectangle. Furnish it with column/guide rail setups, elevators, stairwells and the ellusive concrete core and its see-through hallways. Do it on paper and scan it or take a photo with a cell phone camera.
And answer these already. You sure seem to be able to come up with explanations, but only after the pics are shown to you. Why is that? I've got hundreds of pics. Help me identify the ones you're looking for.
me said:
Can you tell me how would you recognize steel core columns? What sets them apart from interior box columns and elevator guide rails and whatnot?
What is the property of interior box columns, which allows you to identify them as such?
What is the property of elevator guide rails, which allows you to identify them as such?
What is the property of FEMA-style steel core columns, which would allow you to identify them as such, if I showed them to you?
Do you expect any other type of steel columns on the Ground Zero site except for the exterior columns, internal box columns and guide rail columns? How would you recognize those?
You posted this on other forum, but the same could easily go for this thread as well.
I'll continue to ignore you until you come up with evidence from the demoliton photos that show the supposed steel core columns at an elevation above ground
Why such dishonesty? You refuse to define what you're looking for and then choose to ignore those who are unable to present the requested. You're just like a kiddy version of Jimmy Walter's million dollar challenge. You both demand the impossible and it doesn't really matter whether that's for the lack of coherent logic or lack of properly defined rules. Walter at least chose to deal with structural engineers and I believe he does posses the real bucks, while you just give the impression of a spoiled brat in a sandbox, who refuses to allow anyone to play with his little shovel and pail, until they bring him a skybluepink pydbpawngpunr. Don't bother looking the word up, any similarity to an actual word is purely coincidental.
Answer the questions, not just mine, mind you, and provide your floorplans. I'm extremely interested in how your concrete core fits with the "typical enclosed area for elevators and services" from Kevin's pic. Use imagevenue.com or similar to upload your pictures, since you claim that this board's software is beyond your comprehension.
