I'm not sure of the technical term for a sudden collapse. Every so often there's a news story here about somebody who'se back deck fell off their house during a party, killing or severely injuring people. Up to the point the deck didn't fall, it seemed to be normal. Then all of a sudden, in the blink of an eye, the entire deck drops to the ground after some sort of critical point is reached

Nick,
You're showing a picture of the explosion from the time the plane hit the building, and you want me to think that the fire was that intense? That ball of fire quickly dissipated after impact...
Can you prove to me that the fire picture is the same tower as the one with the hole and the women standing there?
There were 2 towers hit and even so, you believe that fire took down the building in 1 hour? I don't, we can clearly agree to disagree on that issue.
And also, While there was a fire, it doesn't really compare with the Madrid fire in fire density, which makes a huge different and is highly relevant.
About your camouflaged personal attacks, I am not misinformed, i am just not gullible to think that the fire in the picture you posted would result in the global collapse of the building in 1 hour time lapse. (Again, we can agree to disagree.)
And about your argument that because the velocity of the plane caused the tower to globally collapse... You must realize that the plane hit the corner of the building mostly missing the center core steel and so the damage is mostly cosmetic and does not affect the overall structural integrity of the whole building....
The world trade center was designed a way that if a plane crashes into it, it's like a pencil piercing a spider web, the impact of one area of the tower does not dictate the force being transfered to the whole building but just that isolated area alone.
So again, we can just agree to disagree, and stop arguing about this because you made up your mind about it and i made up my mind about it and this will just go in pointless circles.

Show me another building that was the same exact design and suffered the same exact damage as that one and didn't collapse. You can't do it. It just doesn't work that way. And you are claiming to be a Civil Engineer?
Oh really? Take that same chair and instead of hacking at the leg try using fire. That's what we are talking about. Would the steel legs all of a sudden just give way with no resistance? Nope, they would bend and deform more slowly than freefall.
OK, let's use fire. At some point the fire is going to weaken that leg and the leg will give and the chair will suddenly fall over. Choose any source you want to take out the support. It doesn't matter. The result will be the same. Of course in the case of the WTC it was not fire alone that brought the building down.
And there you go with the cliche "freefall" claim. It didn't free fall. It was like it essentially fell at free fall, but it didn't Why do you guys keep making this stuff up?
What caused the freefall "drop" of the cap in the first place? It should not have dropped, it should have slumped.
Once again, no freefall. Or if there was freefall, then explain how the debris fell faster than freefall? How did the debris manage to defy the laws of physics? And NO, it would NOT have slumped.
Care to see my credentials? Just because YOU don't understand physics, material science, statics, dynamics, finite element analysis etc. does not prove that what the government has fed you is correct.
You clearly are not being honest. You should understand the most basic principles of engineering which you have shown not to. And the fact that you have to use such cliche lines like "what the government feeds me" etc. I am saying that I think you are a fraud. Or at the very most you are twisting your credentials to mislead people into thinking that you understand structural engineering. You use absolutely NO scientific method in your claims or thinking. You have shown that you clearly have a far fetched understanding of physics that even someone with no expertise can understand.
Please provide some calculations, computer models, steel frame fire tests etc. that support your theory. Because going by 100+ years of known physics, the Cardington steel fire tests (pre-9/11) and even NIST's fire tests and computer simulations prove these hundreds of engineers wrong. Just because you don't understand engineering principles does not make them right.

it is my opinion that there is indeed a grand conspiracy here.
it is my opinion that both towers were destroyed by a lot more than 2 jetliners.
it is also my opnion that building 7 was blown.
the difference between the first two statements and the third is that that the third statement has not one single shred of evidence to support that it was not a controlled demolition.

The weight of the upper towers had to be transferred to the support columns that remained in place after the planes struck the building.
This is nothing like a pencil piercing a spider web because there was a tremendous amount of weight pushing down on the remaining beams.

I guess what I'm going to have to do is when I recieve my PE stamp, I'll stamp a page and sign it for you. Then you can look up my PE number and verify that I am a structural engineer. Would this be acceptable to you or would you ignore it like you've ignored my transcripts?
Crap, I ment to quote this post and not edit it.

Prove I'm not. I have posted my transcripts before. If that is not enough for you, I'll be getting my PE sometime this year and will gladly give you my PE number to be verified.
If he was, he would not be asking questions the way he is asking them.
So, engineers are to be all knowing and can't ask questions?
But I guess since he is listed as a civil engineer on a web site that has no verification process at all, it must be true.
You could easily verify the ones that have PE listed by their name. You can look up anyone who is a PE and verify they are real. Go to the state's board for professional engineers website and look up their name. Soon, you'll be able to do the same with me.
You're telling me that a civil engineer is suggesting that a it's odd that a failed support on a building could cause a sudden collapse instead of slowly falling? I mean that alone should be a red light for you.
No, you are taking what I'm saying wrong or misrepresenting what I'm saying on purpose. Which is it?
A steel column will not buckle all at once from heat. It will bend and deform more slowly than a sudden free fall. And when I say slowly, I don't mean like mollases like you are trying to make it seem.
And, the whole point was to say that the calculations of the cap falling at freefall are eroneous because the cap wouldn't have fallen freefall 12 feet. It should have slumped slower into the rest of the building.
In conclusion:
I DON'T TAKE KINDLY TO BEING CALLED A LIAR!!!!!!!!!!!!

All those calculations and computer models are available to the public in the NIST reports. All done by hundreds of scientists and engineers. And basically you are saying that they don't understand physics and engineering. NIST fire tests do NOT prove the engineers wrong, it proves them completely right. Who are you kidding here????
You think you can tout some credentials and then claim everyone is wrong. It's BS. I am sorry, but enough is enough. Essentailly what you want us to believe is that all the worlds engineers are all incompetent and the 60 engineers on this web site are the only ones who understand engineering. And the criteria for this web site is that you simply have a web browser.

While you may not be "gullible" as you put it, you also do not seem to be well informed, or well educated in terms of the science necessary to even comment one way or another on what caused the collapse.

And there you go again with not reading what I'm saying. Freefall in this sense DOES NOT mean speed. It means with no resistance.
I know this. And you are saying there was no resistance are you not? That of course is simply not true. And no one ever claimed there was no resistance. But as the weight of the top of the building increases with each added floor, the resistance to weight ratio widens as it gets lower and lower. Thus essentially the farther the building falls the less resistance. Well, not so much the resistance changing as the force increasing.
Once again, yes freefall.
So then explain to us how the debris fell faster than freefall speeds? You're saying that there was no resistance so the building fell straight down. Yet the debris outside the building absolutely had no resistance and fell even faster. So if there was no resistance to the building, how did the building fall slower? Was this magic that caused it to fall slower? Or was it magic that caused the debris to fall faster? Two parts of the building with no resistance (according to you) falling at two different speeds. Please explain.
Please point out my misunderstandings. Or better yet, get any engineer that you believe to be an engineer and bring it on.
Well I would start with the 225 engineers that you are claiming are all wrong. Then how about all the others in the world who should clearly be able to see that those engineers are all wrong and don't say anything about it or point out their faults. One misunderstanding is this claim that if a steel column is weakened by fire, that that column will start the collapse and that because it's just weakened that somehow the whole building should just cave in on that column. When instead the load is actually redistributed to the remaining supports to compensate for the weakened one. This misunderstanding that that weakened column is suddenly just snapping because it's too hot. Hey, you're the expert so you say. But so are the other experts.
Piss off. I don't know what more I can do to prove to you I have a BS in engineering with emphasis on structural.
I am not here to prove or disprove your credentials. YOU are the one who has brought them up to enforce your points of view. YOU are the one pushing them not me. And if you are going to use your claims of credentials to push your points, then I have to question your credentials as I question your points.
But hey, Judy has a PHD in physics and that doesn't stop her from making these claims about space beams and microwaves "dustifying" material. The entire rest of the physics world can do nothing but laugh at her claims, but she has credentials. her credentials don't make her right.
If you didn't keep pushing your credentials as eveidence you are right, then they wouldn't be in the point of argument. But YOU brought it into the discussion, not me. And the whole real point of this thread is about a web site touting engineers credentials from a web site that has absolutely no verification process. YOU touted your name being on that web site showing you have credentials. The web site is clearly a fraud even if you aren't. And I am not meaning to say you yourself are a fruad (but the web sit certainly is), but I think you are abusing your credentials (assuming they are true).
Twisting my credentials? How do I twist credentials when I have a BS in civil engineering. Have shown my transcripts with all the structural classes I've taken etc.
See the above reply as it pretty much addresses this as well.
Show me where i have used unscientific thinking.
A couple paragraphs above show some examples. A perfect example though is you making the statement about no other building ever collapsing this way without a controlled demolition. This here is by far the biggest red flag as to your credibility. What true engineer would make such a claim? A true engineer would understand that you can't simply base all rules of engineering on one building. You can't say that because of how one building works, they must all work the same way. Leaving out scientific method is the way you completely ignored the fact that the building was severely damaged and that his wasn't just a fire. The fact that no other building has been exposed to these circumstances.
So, the Cardington tests showed that fire can collapse steel framed buildings? NIST didn't have to tweek their computer models for them to work? Who are you trying to kid?
Another example of your misunderstandings. You keep touting that the buildings collapsed from only fire. You claim the NIST papers prove the engineers wrong, but had you read the NIST papers you would know it wasn't fire. And for the record, fire alone has indeed caused steel buildings and structures in the past to collapse. With no structural damage.
And as for tweaking the models, do you have a suggestion for testing the variables that day? Should they rebuild the towers and then destroy them for testing? They HAVE to tweak the computer models because they have to test all the possible variables. It's IMPOSSIBLE to know what they were inside the building. This is scientific method. And you attacking that scientific method is another example of your lack of scientific method. Perhaps your method would to just skip all research and claim bombs brought down the building. Forget the fact that there isn't a single shred of physical evidence to support that.
I'm not saying all the engineers in the world are wrong. How can all these engineers know what they are talking about without ever seeing the construction documents?

First, quit trying to piss me off to get another warn. If transcripts and a PE number are not good enough for you then you are not even worth the time to speak with.

Please point out my fallacy using engineering basics. Do you know that a buckled column still has some strength to it? It would give freeking resistance. That resistance is not calculated in calculations where people claim that the cap had such and such energy. The cap would not have fallen 12 feet freefall with no resistance. Period.
