Engineer Sees Evidence Of Extreme Temperatures In WTC Steel...

Are this guys credentials up to snuff? Does he understand what he sees? Does he sound credible? Link below:

1. I read, saw the the thermate and closed the tab again n/t

2. Dr. Abolhassan Astaneh-Asl

http://www.ce.berkeley.edu/~astaneh/1-Research/wtc/documents/astaneh-testimony%20congress-march%206%20final.pdf

That's his testimony before Congress on March 6, 2002. And they say there were no investigations of 9/11 besides the Commission!

Please read through that and let us know if he supports controlled demolition or not. Thanks.

3. He believes that fires caused the collapse

So yes, he is credible.

From the conclusion of his paper WORLD TRADE CENTER COLLAPSE, FIELD
INVESTIGATIONS AND ANALYSES

The collapse of the towers was most likely due to the intense fire initiated by the jet fuel of the planes and continued due to burning of the building contents.

5. "He agrees with me. So yes, he is credible"

Lol! In OCTland that's all it takes.

7. And of course we know that truthers never do that. nt

4. I've never understood why CT'ers fail to comprehend

that the fires in the WTC prior to collapse are completely different than the subsequent fires in the rubble pile.

6. What is extreme? Has he numbers or just opinions?

[hack89]

8. He has science

read posts 2 and 3. Google his name.

9. Not totally clear, but some quotes make it look like he thinks steel vaporized before the collapse.

In this quote from a New York Times article, it seems like Dr. Astaneh-Asl is saying he can tell that part of this particular I-beam had vaporized before the collapse:

One piece Dr. Astaneh-Asl saw was a charred horizontal I-beam from 7 World Trade Center, a 47-story skyscraper that collapsed from fire eight hours after the attacks. The beam, so named because its cross-section looks like a capital I, had clearly endured searing temperatures. Parts of the flat top of the I, once five-eighths of an inch thick, had vaporized.

Less clear was whether the beam had been charred after the collapse, as it lay in the pile of burning rubble, or whether it had been engulfed in the fire that led to the building's collapse, which would provide a more telling clue.

The answer lay in the beam's twisted shape. As weight pushed down, the center portion had buckled outward.

''This tells me it buckled while it was attached to the column,'' not as it fell, Dr. Astaneh-Asl said, adding, ''It had burned first, then buckled.''

http://www.nytimes.com/2001/10/02/science/scarred-steel-holds-clues-and-remedies.html

Here is an article where the reporter's paraphrase would seem to say that Dr. Astaneh-Asl thinks he saw other pieces of steel that were as hot as 2000 degrees, prior to the collapse:

To support his theory, he cites the way the steel has been bent at several connection points that once joined the floors to the vertical columns. If the internal supporting columns had collapsed upon impact, he says, the connection points would show cracks, because the damage would have been done while the steel was cold. Instead, he describes the connections as being smoothly warped: "If you remember the Salvador Dalí paintings with the clocks that are kind of melted -- it's kind of like that. That could only happen if you get steel yellow hot or white hot -- perhaps around 2,000 degrees."

10. The severe buckling would seem to rule out nano-thermate

as the cause - it would make a clear cut in the steel. The buckling indicates prolonged exposure to heat - the thermate would have been consumed in seconds.

Interesting stuff. The doctor has some good science to back up NIST.

11. I thought NIST only found evidence for a couple of hundred degrees

[hack89]

12. I suspect that comment was taken out of context

from some NIST report and presented as an absolute conclusion.

Dr. Abolhassan Astaneh-Asl was part of the WTC investigation from the beginning and spent a lot of time looking at a lot of debris. He definitely is not a Truther. His conclusion definitely support the NIST studies even though he was not part of the NIST investigation.

13. And other quotes make it clear that Astaneh-Asl finds it all consistent with simple collapse. n/t
