Why Did the WTC Buildings Collapse?

Question

If you have some time, try to read the report written by scientists and engineers who know about steel, buildings, strengths etc.
The theory that it was fuel from the airplane doesn't work for 3 reasons.
1. While it can burn hot enough to make steel loose its strenth, it is not hot enough to melt it.
2. The 3rd building that collapsed was not hit by an airplane so "fuel" can't explain why it collapsed exactly like the WTC.
There are other reasons that this article examines in a very scientific method.
They plan to present their findings (They are still investigating) in August.

Answer 1

There are alot more than three reasons. Jones presents I believe 13 in his paper. They won't read it, they are afraid of the truth because the official story is comforting to them.

Answer 2

Remember that with any engineering design, they can "factor in" possible events, but they are only ever going to be very good estimates - considering that until 9/11 nobody had ever actually flown a fully laden jetliner into a skyscraper building! Now I'm not a Structural Engineer, but, from the evidence and information on the WTC disaster, I can make some informed guesses of my own. The planes didn;t just fly through the buildings, and then toddle off. They both flew in, and then exploded. This explosion would not only have ripped the plane apart, but also exploded up, down and to the sides. the steel frames where it entered would have been destroyed, as well as the floors above and below, with debris fallind down, destroying and damaging other floors. The explosive power of a jetliner would be pretty big - and that explosion, combined with the fire, would have fatally compromised the steel structure of the buildings, I would imagine. Nothing is ever totally indestructable. In1972, when the WTC was built, it was state of the art. Age also plays a part, and WTC was about 30 years old when it was hit. For the rest of your question - why not do some research yourself and look at the NIST report for your answers. I'm sure it's available to the public.

Answer 3

Not more conspiracy theories, please. The reason for the collapse of the WTC towers 1 and 2 was from an impact with a commercial airliner. The airplane hit causing massive damage to the central structural support. Part of this damage was knocking away the heat and fire resistive barrier from the steel support columns. Now for all those dear engineers and scientist that are in your linked "report" above, they should know that steel expands at the rate of 9 inches per 1000 degrees Fahrenheit. They should also know that jet fuel can exceed temps of 5000 degrees Fahrenheit when it burns. Granted, this is not enough to melt steel, HOWEVER, once steel heats and cools it becomes very brittle. So after being doused in burning jet fuel, the steel expanded exponentially, after the fuel burnt off, the steel cooled, beoming brittle and it was unable to bear the structural load placed on it. Because this happened in both tower 1 and tower 2, they both suffered pancake style collapses within minutes of each other. To imply that this was an inside job is a bunch of BS. A precision drop like that takes a long time to set up, and airplanes flying into the buildings would ruin it. Now, for your 3rd building. After the collapse of the two towers, gas lines were ruptured and water and sewer services were as well. The FDNY was busily searching for surviving members while this and several other surrounding building were on fire. They had extremely limited access after the collapse as well as a very limited water supply. There was no easy access to this building. If anything burns long enough without adequate water flow to quench and cool the fire, it will also collapse. If you really want to learn more about this, Vincent Dunn, retired Deputy Chief from the FDNY, has written several books and articles about this. He is also considered one of the leading experts in building collapse. To access some of his articles, go to http://www.firehouse.com/ and search his name. As far as what makes me a little bit qualified, the fact I have been a firefighter for 10 years and have researched and studied this topic extensively. Collapse is one of the leading non medical killers of firefighters on todays fireground. If you still think it's a conspiracy, why don't you go talk to the widows and children of my 343 dead brothers from the FDNY. Maybe they can set you straight.

Answer 4

The question should be, "How could the north tower collapse?"

What was the distribution of steel down the tower? Doesn't the bottom have to be stronger and therefore heavire to support the weight above? So how can there be any scientific analysis without that data?

Answer 5

The people who spread this 'theory' are just being like Holocaust deniers. The act was obvious and evidence without question. Yet, they come up with great sounding fiction to deny the obvious.

Everyone reputable knows the building collapsed due to terrorists of course.

My question is, why blame an inside job? I understand this is being done in the Islamic world to save face for a horrible act.

One thought I have is liberals like the theory because it makes the Bush administration look bad. And that's their number one priority in life. Their passion is their hate for people with different political views then theirs. It's all part of the demagoguery I saw the left do against Ronald Regan and George W ever since he first got elected. They simply can't understand why anyone would have a different view then theirs. I think a lot of liberals would spread this silly inside job conspiracy theory even if they knew it were false and it helped the radical terrorist who implemented the attack, if it would make Republicans look bad.

To sum up we all know it wasn't an inside job, unless you are not so smart or live in a cave. But, I suppose it is ammunition against the Bush administration. Or, if your an America hater good ammunition against the US.

Answer 6

Did you see the freeway collapse in California the other day?

A fuel truck crashed and caught fire. The heat of the fire weakened the flyover and a whole section collapsed. I'm surprised you've not claimed that was an inside job, as, after all, we all know that fuel burning can't cause something to collapse.

Answer 7

The WTC buildings collapsed because the impact of the planes paralyzed the foundations in the midsection that brought down the top of the building to crushed downwards.

Answer 8

A fuel tanker just recently crashed and burst into flames out in California. It was on an overpass and the over pass collapsed...it melted....steel and all...heat...Gosh!

Answer 9

Experts have already compared the WTC to the bridge collapse in Oakland, as being the same reason for both collapse

Answer 10

its always amusing when someone with absolutely ZERO knowledge of steel makes statements about steels strength at cetain temperatures.

this question has been answered at least 10,000 times. do a question search.

trust me on this, i have no reason to lie, the fire was plenty hot enough for the steel to fail ( it didnt have to melt) under the load that it was supporting.

at 1100 degrees F. structural steel loses 72% of it's strength. melting point is over 2000 degrees F.

Answer 11

Christ! That report must have been written by "scholars" from the clinton school of public fuc/k/e/r/y!!! The fact that ANYONE with a slice of brain more advanced than a clinton or a gore-we're talking the stick I throw to my dog in the yard-would even consider this garbage as even remotely worth anything but a passing glance-speaks volumes for the state of education in this country!!!
