What Kind of Moron Really Thinks This is a "Floors Pancaking" Collapse on 9/11?

That is right. When the WTC went up in the 1960s, building skyscrapers so big posed serious engineering problems, and the solution to that was that the only part of the building which was a truly stand-alone structure was the central core carrying the elevators, plumbing and wiring. The rest of the building, the floors themselves and the outer skin which people saw was all just a house of cards which all got their support and stability tied to that center column.

And what tied the outer skin to the core was the floors which were arranged in spans which merely bridged the gap between the core and the outside to hold it upright and stable so that it didn't buckle and cave in or out. In a way, unlike concrete buildings of the past which were over-engineered and could stand even with a piece of it missing, the WTC essentially relied on every part of it supporting the other parts much like a semi-monocoque design.

This design was used because the developers wished to eliminate structure support columns within the floors so that they could have vast spans with huge office spaces for executive suites and such without any unsightly support columns appearing in the center of these rooms.

Once the fire protection failed, there was nothing to keep these huge floor spans from sagging under their own weight and pulling out from their anchor points; not only did this begin to cause floor failures loading subsequent floors, but it took away key support to the outer skin. Eventually, enough support was lost that the upper section of the building had no choice but to collapse down upon the building below causing cascade failure.

Straight from your handler.

Whereas I only dabbled, you sound like an actual engineer.

Retired from electrical engineering, not civil or architectural, but I have a decent grasp of the basics regarding the whole 9/11 thing.

And this analysis is spot on from what I learned about the towers that semester - from the importance of the outer 'skeleton' to the structure to the design aesthetic of the large open floor office space. Kudos and well done.

Thanks. That was my understanding of the design based on many hours of review.

In its day, a traditional building was built of a heavy super-structure of concrete and steel. Costly to build, it could withstand the loss of most any one given part yet remain strong. But in building the huge size of the WTC, a semi-monocoque was attempted, where all of the strength was contained in the core, with the outer shell and floors being interdependent and being merely built out from the core with no real strength in and of within themselves.

In the late 60s when the WTC was designed, the biggest jets were probably the Boeing 737, with the 747 just coming out after construction had begun. It is my opinion that the larger 767 with greater fuel capacity, the thin outer wall, and the unusual floor spans supported only at their ends, all made the WTC vulnerable.

Then add to that, the jet explosion exceeded what the fire protectant foam had been designed for, blowing off and exposing the steel to the raw heat allowing it to soften to where it could sag enough to fail.

Because then you wouldn't need to keep asking questions already long ago answered.

Except the than any “answers” found here are likely posted by loons, liars or conspiracy theorists.

Towers 200 feet wide, speeds of those cut beams flying calculated at 80 MPH. But some people really really are not going to see anything but what they want to see.

What the **** makes you think one concrete floor could withstand all that weight falling on it?

Have you ever demolished concrete? I've been doing it my entire adult life. Dropping one slab of concrete on top of another is a quick easy way to destroy both.

I fire people like you because you lack any innate sense of physics whatsoever. You people are very accident prone on a jobsite.

I was taking a structures class when 9/11 happened, and we did a case study on the two towers afterwards. Most conspiracy theorists don't take the time to understand WHY and HOW the towers were structurally different then almost every other building built in New York, and why something like an airplane collision was so dangerous to this particular structure. It's pretty easy to dismiss 'theories' almost immediately when the structural design is never considered.

What make the towers unique is what they call the exoskeleton. I learned that from several tours of those towers back in the 80s while visiting from Florida. There are a few other examples of exoskeleton type construction around the world, but there are not that many.

On the contrary, the design worked to minimize the damage from airplane strikes. 20+ years ago I watched several videos interviewing the engineers. They compared the airplane penetrating the exoskeleton to having a pencil pierce mosquito netting if you are familiar with such netting.

The towers were nuked, along with a few other locations in WTC, buildings 5 and 6 as I recall, and those points were very obvious in photos from above including from the AVIRIS satellites overhead. More, USGS took samples around the site. All that is covered in the fine work by Jeff Prager. I would link to his work but you won't read it.

Nothiing ewas nuked that day and no one took samples

You cannot link to his work because you are a liar and full of shit

Is that really the whole basis of your crazy conspiracy theory? I've read the engineering studies by the people who designed the towers; there is no mystery to 9/11. The jets crashed into them and they collapsed due to a design vulnerability.

Pure propaganda you post Toob, a false statement. The towers were specifically designed to withstand strikes by airliners, and the designers specifically mentioned that in interviews I saw 20 years ago.

More, the towers DID withstand those strikes until the controlled demolition was initiated.

For a simple mind like yours there is no mystery, but we don't all have such simple minds.

No they were not and you saw no such interviews

There was no such controlled demolition

Nuked? Why was no uranium or plutonium found?

Why is this in "current events"????

Current as “within a decade or two or so.”

Look fool, the towers were expected to maybe be hit by a small, private aircraft, and were designed to be hit by a 707 or a 727 trying to land, not a 767 under full throttle, and the fire retardant was not expected to blow off. If you studied my drawings at all, you'd realize that the floors themselves in the WTC were designed to be their own structural beams holding the floors and outside tower all together--- once the floor spans began to sag and fail, it was an inevitable process. Frankly, I'm a bit surprised the designers were not held liable.

Dummy, it would take weeks to tear the building apart, install explosives into the structure of the building hidden under all the cosmetics of the building, then clean up all the mess putting everything back in place hoping to get it all half right. Can you produce a single report of people being sent home for weeks then coming back and finding their stuff all moved around?

For a simple mind like yours there is no mystery, but we don't all have such simple minds.

Right. When you can't cover your own bullshit, there is always that last line of defense to try to make it about ME instead.

Yes, except none of that happened to the third tower, WTC7.

Third tower shared the same foundation and supports as the first two. When they collapsed into the basement, that undid the underneath support for third tower. Third towers' basement supports blow out and nothing underneath to hold it up, so of course it collapses.

IIRC, it was the heat generated by the fires heated the steel of the outer skin and support beams enough to soften it and cause it to bow outward. That bowing outward then pulled the support tabs(shelves) 'anchored' to the out wall away from under the floors and with no significant support, gravity pulls them down ward.

Once the process got started with the first floor to lose support and fall onto the one below it, the 'domino' effect was into play.
Also, once the floors under the upper parts of the towers are no longer supporting them, they also will fall downward impacting the floors below them and increasing the hammer effect of the weight pushing down on the floors below the first one to give away.

A chain reaction occurs and the outer walls start to peel away like a banana skin/peel.

Thorium and other substances that are the by-products of nuclear fission WERE found by USGS. Because you seem to live under a rock of sort, YOU (and most other Americans) are simply not aware of that fact.

Because you refuse to inform yourself by reading works by Prager and Bollyn you will likely remain ignorant of those facts for the rest of your life.

Facts exist on their own. They do not need a human to be aware of those facts for their existence.

Thorium isn't a nuclear bomb by product, you moron.
What other radioactive by products were found?

Only 1-2% of the U-235 or Pu-239 in a nuclear bomb is consumed
by the explosion.

Since you admitted none was found, there was no nuke, let alone many.

Ouch. Do you really think I give a rat's sweet ass whether some crackpot like you believing such wholly untenable hair-brained theories any grade-schooler would see through takes me serious?

Easy solution, buster--- just produce the engineering study published by a reputable architectural and engineering firm which has reviewed the facts of the WTC construction and the jet collisions, and came to the conclusion with physical evidence found in hand that the towers were really blown up by demolitions planted and wired throughout the building installed with no one's notice, and then blown up by the US government.

I'm waiting.
