Let's see...

I have had Heiwa admit that a buidling will still stand even if all but one structural support were removed, regardless of the load bearing capacity of that support.

I also recall Terral (I've seen a few posts of his pop up on CTSTDT) insisting that heat transfer throughout a metal structure instantaneously to all points. So that in order to heat the steel in one area (like, say, above a fire) to any degree, the whole structure will have to heat up with it.

Jammonius is too easy...

Not only does NIST have to prove that this is what happened, they also have to prove that the fires got hot enough and burned long enough in the necessary locations.

I'm not saying their hypothesis is impossible, but if you wish to close the case on WTC 7, not requiring some extraordinary physical evidence to back up this hypothesis is just plain stupid.

Ever talked to a firefighter? I,ve seen several concrete blocks walls fail because of steel trusses expanding.

Well, that is mostly true Red. Most fires in steel framed structures do cause some thermal expansion. BUT, it is minimal at best. Maybe a few cm. at the most. And usually not over large areas.

Now, the SFRM in 7WTC was rated for about 2 hours. This gives plenty of time for evacuations and for the firefighters to extinguish the fire. Now, when that fire is allowed to burn uncontrolled for 7 hours (3.5 Xs it's rated protection time) what do you expect to happen?

Just about any office fire will get hot enough to cause thermal expansion. Hell, a hot day in Florida causes thermal expansion in steel and concrete too.

Why is this such a suprise? Thermal expansion is deadly to steel framed structures. This has been known for years.

I wonder if Dave will pounce on you for mostly agreeing and essentially phrasing it the same way I did, namely: "Most fires in steel framed structures do cause some thermal expansion." This is what I stated I simply suspected.

Also, you've proven to be one of the more calm and civil posters I've encountered here, so we can have a productive discussion absent the invenctive, regardless of your unfortunate baseball loyalties.

I don't think I can restate it any more possible ways that I'm not contesting whether thermal expansion occurred in WTC 7, I'm questioning whether it resulted in what NIST said, since as you pointed out, thermal expansion happens in fires, why did it bring the bldg down in this one, since it's never brought a steel framed high rise down before?

My final point on this is that you are suggesting that the fires burned for 7 hours, do you actually think it burned in one location for that long? Of course it didn't so why suggest that the fires burned twice their rating, when the fire had to move around the floors to consume more fuel?

Just to get this clear:

Do you suspect that some fires in steel framed structures do not cause any thermal expansion?

Or do you suppose that all fires in steel framed structures do cause some thermal expansion?

Seymour Butz · 15th July 2010, 08:57 AM

Because of the rare combination of long span floors, unfought fires,a composite floor system the didn't have the studs at that location, and connections that weren't designed to deal with thermal expansion.

It's all in the NIST report.

Quote:

Of course it didn't so why suggest that the fires burned twice their rating, when the fire had to move around the floors to consume more fuel?

NIST used a rather sophisticated sytem of programs (FDS and FIS, IIRC) to predict the steel/concrete temps. This takes into account all factors like fire location and duration in any location as it moved about the floor, SFRM insulation, office compartmentization, etc.

If you have a better way of predicting the floor steel and concrete temps than what NIST used, feel free to present it.

Why do you assume that after an hour or two of fire, when all fuel is consumed the floor returns to ambient in minutes and not hours, many hours?

Can we say "heat soak"? Of course we can. Maybe you can't.

I suppose RedIbis is right about one thing: this is also untrue. All fires in all structures cause thermal expansion. Other than some extremely exotic materials, any form of heating of any kind of structure causes thermal expansion. The belief among truthers that thermal expansion was made up by NIST is one of the most bizarre developments in the sorry saga of 9/11 truth.

CORed · 15th July 2010, 09:38 AM

Replying to OP here. There is so much in the truther world that is mind-boggling in its stupidity that it is difficult to choose, but I'm going to have to go with Jammonius refering to the plane in the videos as a "shadow thingy". Of course, the whole thread where he cited videos of the planes hitting the towers as evidence that no plane hit the towers was one of the most astounding exercises in self-debunking I have ever seen.

grandmastershek · 15th July 2010, 09:41 AM

too many to list.

but my fav is a guy i know in real life. it's been 10 months and he still thinks free fall is a speed. and just when he thought he had it, he started saying "accelerated free fall"; as if there is an unaccelerated free fall. now he's just back to calling it free fall speed.

9/11 Chewy Defense · 15th July 2010, 10:13 AM

That "No Planes" were involved, but thousands managed see & hear the planes with their eyes & ears.

That "holograms" were used to disguise "missiles".

That Flight 93 was "shot down" near Shanksville, PA. (I live 20 miles North of the town & Flt. 93 wasn't "shot down". At Johnstown Airport, we only got Apache Helicopters & even they wouldn't have brought down Flt. 93, due to the fact that they fly slow to catch a plane going 500 mph. Beat that Truthers!)

You all know the rest!

Dave, Dave, Dave, semantics and strawmen are no way to have a civil discussion. Who said that NIST made up thermal expansion?

What's being questioned (I can't believe how many times I have to say this) is that thermal expansion causes column collapse and then column collapse causes global collapse.

But I can see why you want to avoid defending these unsupported claims.

Do you have an alternative theory that explains all the known facts as well as the NIST model, and is better supported?

We're dying to hear it!

If you don't have any such theory, is it then fair to say that your personal incredulity about the NIST model is no better supported than the model itself?

You could start by understanding what NIST said, not what you think they said. For starters, they didn't claim that the failure of a column initiated the collapse of WTC7.

You have no more way of knowing how NIST calculated the failure modes as anyone else. It's not available to you, so you must take it as a matter of faith.

Yet again you have proved you have not even read the WTC7 report. This is too funny.

Grizzly Bear · 15th July 2010, 02:35 PM

Isn't there also something referred to as flash point, or ignition point which establishes a minimum temperature at which materials begin to, and sustain combustion? Something similar to the whole issue of why windows shatter in many building fires...

NIST explicitly describes the failure mode.

Yes, also know as their ignition point. All flammable materials have an ignition point. Suprisingly, paper has one of the highest of common materials. Plastic in general light at a lower temp than paper.

Suprising? Yes. True though.

I once called into a conspiracy theorist radio show because they were getting all cocky about how they're right and the skeptics are wrong. By far the dumbest thing I heard was another caller who said that someone ran a test where they dropped a bowling ball through all these sheets of glass and timed it, and apparently it was longer than the time it took for the twin towers to collapse, so doesn't that prove a conspiracy? And the two hosts, after hearing the question, were totally on board with it. Comparing the collapse of one of the most intricately-designed buildings in the world with a bowling ball breaking through glass. I believe this is where I say lol.

I have an anecdote from the other side just for the balance.

This one always makes me laugh. It was about how small the fires really were in the Towers. I dropped a little bait by remarking that 'those fires could have been knocked down with two lines' Of course they puffed up their feathers and piled in saying how ridiculous that was and that the fires were massive. Grizzly was frantically waving his arms and warning them in the background to no avail ? I guess the PM's were flying too. Sigh....I really enjoyed hitting them between the eyes with the live audio of the fire chief on the 78th floor saying that ' there were only two isolated pockets of fire that they could knock down with two lines'

Grizzly seemed to get really mad when I said 'Good fishing today, eh Grizzly ' or words to that effect. There have been many such memorable occasions.

Thermal expansion PLUS the fact that the yield strength of steel drops off dramatically at elevated temperatures. Over 800c it is reduced by 90%.

Hehe

That one is pretty high on my list of truther stupidities.
I mean truthers misconstruing a statement about local conditions (78th floor, well below impact zone and the several floors that were heavily engulfed in massive fires) as being representative of overall conditions.

Dave Rogers · 16th July 2010, 05:46 AM

Ah yes, the classic truther stupidity of assuming that Oreo Palmer could see every floor of the South Tower from inside the 78th floor, and that his report that there were two isolated pockets of fire on the 78th floor therefore meant that there were no other fires on the 79th, 80th, 81st, 82nd,....

Poor bill smith, poster-boy for the Dunning-Kroeger effect. Even when he tries to be clever he ends up making himself look stupid.

NIST used a rather sophisticated sytem of programs (FDS and FIS, IIRC) to predict the steel/concrete temps. This takes into account all factors like fire location and duration in any location as it moved about the floor, SFRM insulation, office compartmentization, etc. If you have a better way of predicting the floor steel and concrete temps than what NIST used, feel free to present it.

BigAl Philosopher Join Date: Jun 2007 Posts: 5,397	Originally Posted by RedIbis My final point on this is that you are suggesting that the fires burned for 7 hours, do you actually think it burned in one location for that long? Of course it didn't so why suggest that the fires burned twice their rating, when the fire had to move around the floors to consume more fuel? Why do you assume that after an hour or two of fire, when all fuel is consumed the floor returns to ambient in minutes and not hours, many hours? Can we say "heat soak"? Of course we can. Maybe you can't.

Most fires in steel framed structures do cause some thermal expansion. BUT, it is minimal at best. Maybe a few cm. at the most. And usually not over large areas. I suppose RedIbis is right about one thing: this is also untrue. All fires in all structures cause thermal expansion. Other than some extremely exotic materials, any form of heating of any kind of structure causes thermal expansion. The belief among truthers that thermal expansion was made up by NIST is one of the most bizarre developments in the sorry saga of 9/11 truth. Dave

There is so much in the truther world that is mind-boggling in its stupidity that it is difficult to choose, but I'm going to have to go with Jammonius refering to the plane in the videos as a "shadow thingy". Of course, the whole thread where he cited videos of the planes hitting the towers as evidence that no plane hit the towers was one of the most astounding exercises in self-debunking I have ever seen.

That "holograms" were used to disguise "missiles". That Flight 93 was "shot down" near Shanksville, PA. (I live 20 miles North of the town & Flt. 93 wasn't "shot down". At Johnstown Airport, we only got Apache Helicopters & even they wouldn't have brought down Flt. 93, due to the fact that they fly slow to catch a plane going 500 mph. Beat that Truthers!) You all know the rest!

Dave Dave, Dave, Dave, semantics and strawmen are no way to have a civil discussion. Who said that NIST made up thermal expansion? What's being questioned (I can't believe how many times I have to say this) is that thermal expansion causes column collapse and then column collapse causes global collapse. But I can see why you want to avoid defending these unsupported claims.

We're dying to hear it! If you don't have any such theory, is it then fair to say that your personal incredulity about the NIST model is no better supported than the model itself?

For starters, they didn't claim that the failure of a column initiated the collapse of WTC7.

Grizzly Bear このマスクによっ Join Date: May 2008 Posts: 7,792	Isn't there also something referred to as flash point, or ignition point which establishes a minimum temperature at which materials begin to, and sustain combustion? Something similar to the whole issue of why windows shatter in many building fires...

Suprisingly, paper has one of the highest of common materials. Plastic in general light at a lower temp than paper. Suprising? Yes. True though. http://www.economypoint.org/i/ignition-temperature.html Here is a neat little link I love to use. http://webbook.nist.gov/

chippy Muse Join Date: Nov 2006 Posts: 521	I once called into a conspiracy theorist radio show because they were getting all cocky about how they're right and the skeptics are wrong. By far the dumbest thing I heard was another caller who said that someone ran a test where they dropped a bowling ball through all these sheets of glass and timed it, and apparently it was longer than the time it took for the twin towers to collapse, so doesn't that prove a conspiracy? And the two hosts, after hearing the question, were totally on board with it. Comparing the collapse of one of the most intricately-designed buildings in the world with a bowling ball breaking through glass. I believe this is where I say lol.

bill smith Philosopher Join Date: Feb 2009 Posts: 8,408	I have an anecdote from the other side just for the balance. This one always makes me laugh. It was about how small the fires really were in the Towers. I dropped a little bait by remarking that 'those fires could have been knocked down with two lines' Of course they puffed up their feathers and piled in saying how ridiculous that was and that the fires were massive. Grizzly was frantically waving his arms and warning them in the background to no avail ? I guess the PM's were flying too. Sigh....I really enjoyed hitting them between the eyes with the live audio of the fire chief on the 78th floor saying that ' there were only two isolated pockets of fire that they could knock down with two lines' Grizzly seemed to get really mad when I said 'Good fishing today, eh Grizzly ' or words to that effect. There have been many such memorable occasions.

Over 800c it is reduced by 90%.

I mean truthers misconstruing a statement about local conditions (78th floor, well below impact zone and the several floors that were heavily engulfed in massive fires) as being representative of overall conditions.

Dave Rogers Bandaged ice that stampedes inexpensively through a scribbled morning waving necessary ankles Join Date: Jan 2007 Location: Cair Paravel, according to XKCD Posts: 28,323	Ah yes, the classic truther stupidity of assuming that Oreo Palmer could see every floor of the South Tower from inside the 78th floor, and that his report that there were two isolated pockets of fire on the 78th floor therefore meant that there were no other fires on the 79th, 80th, 81st, 82nd,.... Poor bill smith, poster-boy for the Dunning-Kroeger effect. Even when he tries to be clever he ends up making himself look stupid. Dave
