Most detailed scientific papers for and against controlled demolition

[Dave Rogers]

Or anyone have a link to previous progressive collapses in steel structured buildings that have occurred in a similar fashion?

I think it's fairly safe to say that it's highly unlikely that any steel structured building has collapsed in a similar fashion to WTC7 while being filmed, so there won't be anything to compare with the velocity curve. In general there appears to have been a vanishingly small amount of study of the time dependence of the velocity of falling buildings as a function of cause of collapse, which means that it's very difficult to derive any useful information from the data. Of course, this totally invalidates the vast majority of truth movement claims that the collapse velocity indicates a specific mode of initiation.

Some studies have been made, and results shown on this forum, of the collapse curves for explosive demolitions. However, at most they can only illustrate that the collapse mode doesn't rule out explosive demolition; since the audible record effectively rules it out anyway, that's not a particularly helpful result.

Dave, do you have a link to any of the CD velocity curves? I can't remember seeing one.

 

[Dave Rogers]

Dave, do you have a link to any of the CD velocity curves? I can't remember seeing one.

I think einsteen, who has since deregistered as a member, posted some smear-o-grams of WTC1, WTC2 and WTC7, but I don't remember in which threads. I never seem to get anywhere with it, but if you possess the mystical powers required to make the forum search function actually do something useful, you could try searching by username.

Judging from the lack of people linking to any papers that show plausible evidence for a controlled demolition of some sort Im forced to conclude that there probably exist none. So far ive found most of the papers written in the journal for 9/11 studies laughable and sort of aimless, assuming a conspiracy and trying to prove it, not just looking at the evidence. They seem to choose the facts they want and ignore the bigger picture.

WTC7 is still a bit odd in my opinion. Anyone have a link to the velocity curve for WTC7's collapse? Or anyone have a link to previous progressive collapses in steel structured buildings that have occurred in a similar fashion?

How did you conclude it was odd without looking at the velocity curve?

Ahhh...the ole "it doesn't look right" argument.

It's on slide 64 of that tedious report you said you read. The one that gave you all those suspicions you listed.

Yes unfortunately it is a common thing to focus on segments rather than the whole event. No doubt the collapse of 7 WTC was "shocking" and indeed looks very similar to a CD but there is just no solid evidence that points that way. CD believers always tend to say there was a considerable amount of charges used but there is no visual or auditory evidence to back this except a faint boom in the north face NIST video ... which could easily be explained as the floors starting to fall out.

WTC7 is still a bit odd in my opinion.

I agree but odd doesn't prove conspiracy.

Anyone have a link to the velocity curve for WTC7's collapse?

I am sorry I don't and there is nothing to compare it to if we did ... that i know of.

Or anyone have a link to previous progressive collapses in steel structured buildings that have occurred in a similar fashion?

I can't think of one but that isn't suspicious to me either

 

[dtugg]

Or anyone have a link to previous progressive collapses in steel structured buildings that have occurred in a similar fashion?

No other steel similar steel structure endured what WTC7 did (huge multi-story fires that burned for several hours without being fought at all).

 

[Zeuzzz]

Ahhh...the ole "it doesn't look right" argument.

Yes. Exactly.

I'm not quite sure how to respond to these odd snippets ... how else do u judge something other than looking at the video evidence and forming an opinion?

 

[WildCat]

Yes. Exactly.

I'm not quite sure how to respond to these odd snippets ... how else do u judge something other than looking at the video evidence and forming an opinion?

Can you quantify "it doesn't look right"?

Just what would you expect to happen?

 

[carlitos]

Yes. Exactly.

Some people read the NIST reports. Some people even provided a link to them in this very topic.

Margaret Thatcher to be piloting the plane that was artificially computer animated by FOX news to make it look like Al-Queda had destroyed the towers when in fact it was Bill Oddy sending a huge swarm of badgers under the Atlantics secret CIA built underground tunnels which gnawed through the foundations of the twin towers causing a collapse nearly identical to a controlled demolition.

Happy now?

It's their list of articles attempting to portray "scientific consensus" regarding the progressive collapse theory of the WTC, as espoused by NIST and Bazant. The briefest perusal shows that 90% of it is fluff. Not that the articles aren't scientific or peer-reviewed. It's just that very few of them are actual discussions and confirmations of the collapse scenario supposedly supported by the "vast majority" of the world's scientists.

Hence, it is seen that the flame temperature of fuel (1727oC) melted the steel columns (melting temperature of steel is approximately 1570oC). Even if the temperature was half the flame temperature, the steel would creep rapidly, losing its strength, resulting in buckling. When one floor collapsed, the weight of the floors above created an instantaneous ‘pancake effect’, each floor collapsing on the floor below.

That the World Trade Center Towers withstood the impact loads of commercial aircrafts on September 11, 2001, was not surprising for structural engineers. However, very few in the profession expected the collapse of the towers during the fires that followed.

in direct contradiction to Bazant, who said that no structural engineers should be surprised by the towers' "inevitable" collapses.


Collapse of towers as applied to September 11 events Cherepanov, G.P. 2008 Materials Science 44 (4), pp. 489-499:

The subject of the paper is the collapse of towers and highscrapers, particularly, the collapse of the World Trade Center towers in New York on September 11, 2001. The deduced equations of progressive collapse are used to refute the generally accepted opinion of experts about progressive collapse of the WTC towers in the free-fall regime, which is the official version of the US government. It is proved that progressive collapse is much slower than free fall. The critical floors where collapses started from are estimated using the well-established fact of the free-fall time of all WTC collapses. To this end, the most comprehensive “hybrid” analysis is advanced taking into account that collapses could start on several floors simultaneously, not on one floor as suggested before. According to this “hybrid” model, at the first stage, several floors collapsed simultaneously as a result of fracture waves causing a dust cloud and, at the second stage, the lower part of tower being intact in the first stage collapsed in the regime of progressive failure. Five different collapse types are studied, including the fastest and slowest collapses, and then the hybrid mode is examined with initial collapse of several floors followed by the “domino-effect” of the remaining floors. It is established that the floors where the WTC collapses started from were located significantly lower than the floors hit by the terrorists and subjected to fire. This conclusion confirms the same former result obtained by using the simple official theory of pure progressive collapse.

- Yes, the buildings held up well to the airplane impacts. What does this have to do with anything?

Yes with all the fake debunkers and fake truthers around it gets difficult to see who is on what side.

It seems to me that you are a fake truther. Why else would you show a list of papers when not one of the authors has signed our petition. You are just trying to embarrass us

 

[ergo]

Bedunkers have a petition? Do share!

 

[grandmastershek]

Yes. Exactly.

I'm not quite sure how to respond to these odd snippets ... how else do u judge something other than looking at the video evidence and forming an opinion?

By examining all the evidence and not deferring to my own personal incredulity.

Bedunkers have a petition? Do share!

No...we deal in logic and evidence. You guys like making irrelevant lists.
