NIST Releases Report On WTC 7 Collapse
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."

No! You stole my +5 funny!!

What site is this, and what has it done with Slashdot

MABASPLOOM!

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?
"Yes, But did they run linux?" No, XP/Vista - that's whay it took 3 years to do the graphics.
Do they mean to say that a fire can cause a building to collapse? Next they'll be telling us damage to structures following earthquakes isn't manmade.
but you can still publish goatse links here.
Their they're doing there hair.
Everyone knows the CIA hired the mob and anti-Communist Cuban militants to bring it down.
As soon as it is Slashdotted, someone will come along with, "hey, they are blocking access to the report - what are they hiding?"
I am sure it was the gay space aliens under comander Elvis what done it. Oh, and superglue took care of MY pot thank you!

If someone left a crackpot burning, couldn't that have started the fire in the first place?
Ipso diabolico facto nonsensicalico.
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.
Sheeple, the answers are RIGHT IN FRONT OF YOU, just light them up and breathe deeply.
Not really. Just better government.
no, that was because the technician downloaded Smiley Central.

Asking Slashdot readers to stick to science, refrain from discussing conspiracies, AND taking the fun out of a beowulf cluster reference?
This submitter is a black belt troll and you all know it!
That's just one of many theories. Some say it was done with Pop Rocks and Soda. I happen to believe it was done with Mentos and Diet Coke.
Which way would you expect a building of that size to fall?
Toward Osama bin Laden's massive ego.
Knowledge is how to play a game, intelligence is how to win, wisdom is knowing what game to play.

Guess we should try not to get the pages stuck together huh?
Nobody wants a set of dominoes that large.
Speak for yourself...
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.
You can't take the sky from me...
You know what, Stuart, I like you. You're not like the other people here in this trailer park.

You generally have to wait for the brai... fluids inside to boil off before the aluminum container will melt.

o0t!

Wow, you've never met a human male, have you?
The world you experience is only a close approximation of reality.
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.
"Another big reason large buildings tend to fall straight down is that is the direction gravity is pulling them."
Bullshit - Gravity is just a theory, just like Evolution.

If you Buy Fraggle Rock, Season 2 on DVD and watch episode 36, titled "The Doozer Contest," you will find, about 3 and a half minutes in, Flange saying "Look the Fraggles are Destroying the North Tower" and then all of the Doozers Cheer. If you don't believe that this is proof positive that Jim Henson was behind the events of September 11th, then you are a disinformation agent and a muppet of the shadow government.

Nine-eleven who?

That must be nice to have all the facts. Not like all those so-called experts, they don't know anything!
Why won't slashdot let me change my terrible username
Or why the BBC reported its fall 20 minutes before it actually fell.
Is that seriously the best argument you fuckheads can come up with? That a news organization got a fact wrong? Don't you morons remember "Dewey Defeats Truman"?
If you mod me Overrated, you are admitting that you have no penis.
Don't you morons remember "Dewey Defeats Truman"?
exactly! Another great conspiracy! The man who dropped the atomic bombs on Japan mysteriously wins the election!!!
A fool and his money are easily parted.
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.
