Tampa 9/11 Truth

The “War on Terror” is a Fraud!

Two Floors of WTC 1

Just an update on the WTC drawings that I am doing (more here).  I am modeling a 12 floor section of the Trade Centers and my little computer here doesn’t like rendering it all (poor thing) so I thought I would cut out 2 floors worth and share them with you guys. Some things are missing like the diagonal bracing in the core section and the “I” beams that span some of the openings in there for the floors. Also, I haven’t included the transverse trusses on page 2.

As you can see, the trusses were an immense part of the structure of the buildings. As large and sturdy as the core was, the truss system was quite extensive.  The trusses and the concrete floors would have been a serious problem in the demolition process.  I think within all those metal spheres that Steven Jones found, lies the answer to what happened to 110 floors of all these trusses.

The concrete itself was reinforced lightweight concrete at 4″ thickness.  “Reinforced” means it had steel rebar running through it in a check board pattern.  There was also 5″ thick higher density concrete in the core where there were floors and not elevator shafts.  All this pulverized concrete is what coated lower Manhattan.

Most people don’t have a clear understanding of the massive size and designed capacity of the core structure of the WTC towers.  That’s not their fault.  Many media outlets downplayed the structure in the first year or so after the attacks.  Considering that details about the design of the building were not that hard to come by, one has to ask why they would do such a thing.  Popular Mechanics and the PBS/NOVA efforts were probably the most glaring examples.

My drawing are based on the architectural drawings and several pictures you can find dating back to when they built the towers.  Pictures I have included at the end here, and the construction drawings (actually the architectural plans) can be found at the link on the right over there.

Let me know what you think. There is a reason I am doing all this, trust me. Just keeping you up to date.

You can see the tension and compression bracing in this shot. Also, you can see some of the “I” beams used to support the floor systems as well. This was an incredibly strong core structure. What the MSM referred to as a “hollow tube”.

As you can see, I have modeled my exterior columns exactly the same way as they were built. Each of these sections was 3 stories tall, welded together in the factory and installed as a unit.  They then bolted, and welded into place.  Again, when you see drawings of these, often you don’t have the detail included that you need to understand just how strong this design really was.

So, I hope you can see that I am working as closely as I can to what I have found to be the actual construction of the towers.  It’s not perfect, but I am working on it.

(just a note:  if you look at the floor there, that is prior to pouring the concrete. They haven’t yet installed the rebar either. But you can see the steel from the trusses poking up through the floor.  What that is, is part of the truss that runs up through the top cord of the truss, and then is actually embedded in the concrete when it is poured.  What that means is, when NIST tells you that the floors buckled 40″+ (even though Kevin Ryan tells us that the UL Lab tests only produced <2″ of deflection, which NIST eventually admits) they are trying to tell you that all those steel loops, embedded in that concrete, somehow shifted allowing the steel and the concrete to move independent of each other.)

Imagine the force it takes to propel not just one of these massive sections over 300 feet into another building, not two, but three. (Also note that one of the reasons that NIST’s consultant told them it wasn’t a controlled demolition (one of the two reasons he gave) was that not enough damage was done to the windows of surrounding buildings, as often happens with controlled demo (according to him, a controlled demo expert in charge of clean-up the next day).  Notice any damage to the windows?

    Nice work so far. Two issues that I’d like to point out. From what I’ve read, I don’t think the exterior column sections were welded together, only bolted. This would explain why the exterior columns came apart at the original joins and certainly would have made demolition a lot easier.

    Second, from what I recall, they used aggregate concrete pouring into steel pans. Are you sure about the rebar? I don’t remember seeing anything about rebar in the floor slabs.

      Hi:

      You make a good point; the exterior column sections were bolted together at the joints, top and bottom. They were also bolted at the lapping flinch-plates but then, those plates were actually welded as well.

      One interesting thing. The bolted connections were between where the windows are, so anyone looking to blow those would have to put a charge in an area that was easy to see (unless they fixed the drywall). However, as you can see from the drawings below, the flinch plate welds would have been in between the metal floor pan and the dropped ceiling, so they could have used a thermite (thermate) cutter charge there and no one would have seen it.

      As odd as it may sound, I think I have a picture from the clean-up that shows an unexploded cutter charge.

      But I think you may be right in that they didn’t weld the butt joints of the columns.

      As far as the use of rebar is concerned, yes I think it was used on the upper floors. Back then (and now for that matter) “lightweight” concrete used less aggregate and rebar to reduce weight loads.

      Though I am finding it hard to locate images of the detail, there is a good discussion of it’s use or not on 911B including images and video. I have several pics taken during the clean-up and rebar is everywhere.

      The rebar wouldn’t do much to prevent the demolition of the concrete in the manner I described, but it would do a great deal to prevent the “40+”” of bowing that NIST claims caused all of this.

      I am not still perfectly sure about the rebar, but I believe that it was there. Any information on the subject would be appreciated.

    40 years ago I was attending grad school in the CGE Department at Princeton. One of my fellow students, Luis Prieto-Portar (check out his website!) was working on the WTC. I still remember that he as very upset that the re-bar for the flooring was not being properly clipped together. I have often wondered whether or not this played some role in the failure of the upper flooring structures

    wow great WTC drawings and modelling, nice jobs friends. I am basicly mechanical engineer on welding structure, after see your drawing and modelling I think your drawing is good structure.

    The mini nuke used on Bali-the concrete was stripped from the rebar-same as Japans concrete/rebar & 911

    im builder the wtc in sketchup part by part component by component its not going that fast though if finishd 1 floor but i keep correcting litle parts and seeing this means ifgot to redo the core XD
