NIST Releases Report On WTC 7 Collapse 1331
photonic writes "After three years of study, the National Institute of Standards and Technology (NIST) finally released its report on the collapse of World Trade Center building 7. The main conclusion is that the building came down due to fire, not due to debris damage or some conspiracy demolition team. The fire started pretty small after the collapse of WTC 1, but was left to burn several floors out completely. The important finding is that the collapse was triggered by thermal expansion of beams, which could detach asymmetrically loaded girders from the main columns. Some limited pancaking of floors then caused a lack of lateral support and buckling of a single column. This triggered the failure of the entire core of the building, which finally fell down as a single piece. Crackpot theories can be discussed elsewhere; please limit the discussion to the science here. All documents can be found at NIST's WTC page, which read like a porn magazine for finite element junkies. Simulation movies are also available. And yes, they used Beowulf clusters to do the simulations, some of which lasted for several months."

Let's just get this out of the way first. BULLSHIT!
The rest of the world knows something suspicious went on, but America has their head in the sand.
Not long after this shit, there was a building in Europe, where the fire was so intense, it burned everything off. The steel structure was still standing but oxidizing flame was enough to melt or buckle steel in the trade center? The sheer ignorance of the American populace astounds me.
Interesting. Then I am curious as to what temperature would be required to melt and/or buckle the structure of your aluminum foil hat?

These guys have resources. It could be quite damaging to be caught with a smoldering crackpot.
Ergo, they crash a plane into the building to cover it all up.

Surely, if it were easier to get a building to topple over sideways, a team of terrorists isn't going to go through the trouble of averting what would surely be a larger and more spectacular catastrophe.
Which is why efforts to keep the damage to a minimum would point to an "inside job" conspiracy rather than a "bunch of guys in some desert cave" conspiracy.
Duh.

The way that a skyscraper is designed and built favors it falling more or less straight down rather to one side or the other. The reason being that if it were to topple, as remote a possibility as that is, the building shouldn't be allowed to hit other buildings. Nobody wants a set of dominoes that large.
I can safely say with 100% assurance that that is absolutely not true. I would kill to see a set of dominoes that size.

With due respect to the authors of this official report and their three years of computer simulations, I do not believe for one moment that thermal expansion from the burning of paper, desks and plastic fittings (even over a period of many hours) is sufficient to explain this. I also do not think it can explain molten steel in the wreckage weeks after the event.
Translation: My common sense is more reliable than all that engineering, science, maths and computer simulations.
You should start working as a holistic civil engineer. I'm sure companies will be thrilled at all the money they could save by not doing any actual engineering and simply letting you intuit the correct answers.
