I stay anonymous because I once had a kook try to threaten me in real life.
Some bozo was able to figure out who / where I was and threaten to contact my "employer" for posting on a message board during working hours because I had made him look foolish , (too bad for him, I was a owner / partner ) when that failed he threatened to libel the company to leave a "permanent black mark on the internet"

Ahhhhh.......then you arent doing things right. Take a leaf out of Gage's book. Get ya self out there. Lose ya wife. Come out of the closset and put ya real name forward. Screw ya job and credibility because you can earn £100'sK per annum for spewing *****. Plenty of idiots who lap it up. You can never go back to your real job though. Especially if your an architect. Who the **** would employ your services ever again. Need to keep spewing ***** for a living.

Or ya could just remain anon and take the piss instead.
 
Chris7,

No, no. List the names please.

Great response, Chris.

Hypocritical, illiterate & deceitful.

Allow me to explain in clear, measured tones that comply with the MA.

1. Hypocritical
One page ago, you had your panties in a bunch about a couple of posts between Animal & I, insisting "May I interrupt this conversation and bring this thread back to the topic? The 5 1/2 inch girder WALK-OFF in the NIST theory …"

Now ergo tosses out Troll-droppings, and do you respond in kind to him? No, you don't. Because you think that there is some hay to be made, you join in with a wall of irrelevant, off-topic, quote-mined text.

When you have a different set of rules for yourself than for others whenever you find it convenient, that's called "being a hypocrite".

I am sure that you'd agree...

2. Illiterate (in this case, "innumerate")

He said he bet I couldn't name ONE NAME.

I gave you 300% more than that in 6 words & 3 commas.

3. Deceitful

You imply that James Quintiere's name doesn't belongs on that list. And you highlight selective words that suits your fantasies.

You attempt to leverage his reputation as a respected engineer, at the same time as you routinely denigrate the significance of having any engineering expertise to interpret these events. (Sorry, my bad. This belongs under "Hypocritical" above.)

But you pull out this wall o' text, full of irrelevancies & outdated facts in order to DECEPTIVELY imply that Quintiere is on the "truther side" of this issue.

Allow me to substantiate my assertions:

Irrelevancies:
Quintiere said:
"Little did I realize that the NIST heart was not in it, and its efforts would not be proactive, but reclusive.

This is Dr. Quintiere's inexperience talking. These investigations are always reclusive while they are in process.

The "reclusive" part ended when they released their 10,000 page document explaining their analysis, methods, justifications & conclusions in exacting detail.

Outdated facts:
You are quoting a comment that he made in 2005, while the investigation was incomplete.

Quintiere said:
While NIST had public hearings during the course of discharging their findings, they were limited to 5-minute presentations by the public, and no response to submitted questions or comments.

Now NIST has had many presentations to the public, and numerous responses to submitted questions & comments.

So his objections on this matter have been resolved.

That is an example of Dr. Q's outdated facts.

For an example of YOUR outdated facts:
It's now 2012 & all the reports have been released. And yet, deceptive quote-mines from 2005 is the best you have to offer of Dr. Q's objections…?!

Pretty lame.

Deception:

Dr. Q's REAL conclusions, even at that time:
Quintiere said:
Conclusions

I contend that the NIST analysis used a fuel load that was too low and
their fire durations are consequently too short…

An alternative hypothesis with the insulated trusses at the root cause appears to have more support … [and] puts the blame on the insufficiency of the truss insulation. Something NIST says was not an issue.

Missed the part about what this has to do with WTC7. (Oh yeah. "Nothing".)
Missed the part about "bombs in the buildings", Chris.

I do NOT miss the part about the fact that you have produced not one single quote from Dr. Q which he supports the "truther stance".

Total lack of respect for and adherence to Rule 12 noted.

JREF MA said:
Rule 12
This rule does not apply only to direct insults and attacks (which are often also a breach of Rule 0) but is intended to ensure discussion stays focussed on the topic at hand and not on the Members involved.

My comment didn't violate Rule 12 in the slightest.

I cast no aspersions at Tony, the individual.
I denigrated HIS RESPONSE as "incompetent".

And then proved that it was.

I denigrated as "stupid" his argument that the size of the building played any role in "how fast it fell".

And then proved that his argument was exactly stupid.

I think that you need to read Rule 12 again.

That is an erroneous interpretation of the data that only the fanatically faithful on this forum support.

LOL.

The data is the data.

If you want to argue with the data, be my guest. Thus far, you've made not one single argument against my analysis.

And you're not going to make any argument against it. Because you aren't capable of making an argument against it. That is clearly beyond your technical skill, as proven by the fact that you've not attempted to make a single argument against it.

Your chosen path on the matter, simply repeating that it is wrong, over & over with zero supporting argument, is simply childish.

Are "childish repetitions" the best that you have to offer?

Real engineers give their real names and credentials. You are just an anonomous poster and not an engineer - except in your own mind.

What was that "Rule 12" injunction again?
"… to ensure discussion stays focussed on the topic at hand and not on the Members involved."

Hmmm, we may have another example under "hypocrisy"…

BTW, I've given my name & verified credentials to several people here that I thought could be trusted with that information.

You didn't make the list.

Neither did Tony.

Sorry.

TFK can't even cite himself, because anonymous engineers don't count. I am continually amazed that a working mechanical engineer, as he claims to be, has as much time as he seems to have to post here and elsewhere.

Tony:
A couple of years ago you agreed (I believe you were going to debate Tom) that if I could verify his credentials that would be acceptable to you. As you know, Tom did in-fact send me his information that I was easily able to verify.

I have no intention of getting into a pissing contest about this but, I can assure you, Tom is who/what he says he is. His posts, actually should tell you that.

This line of defense is not in anyway helping your case.

Anyone with any real understanding of them knows rocket and jet engines don't push against anything external to propel themselves. They push against the internal pressure wall while the exhaust is just to let the forward component of the pressure dominate without being countered.

If rockets didn't work like that they wouldn't work in space. The only difference with the jet engine is it uses atmospheric oxygen for combustion.

You may understand these trivial issues, but your explanations suck.

1. "... rockets & jet engines ..."

"THEY push against the internal pressure wall ..."

Jet engines don't have an internal "pressure wall" (the front wall, opposite the exhaust). Kinda gets in the way of air entering the turbine.

"... while the exhaust is just to let the forward component of the pressure dominate without being countered."

"Exhaust is just to let the forward pressure dominate..."??

Oh, yeah, and that other trivial little point: "without the exhaust, it don't work."

The only difference with the jet engine is it uses atmospheric oxygen for combustion.

"... oh yeah, and jet engines don't have that pressure wall that I identified as the seminal reason why rockets work."

Chris7,

Shades of Chandler's glaringly erroneous physics statement...

No, this is the only data on buckling that I know of.

And this statement, this statement right here, is EXACTLY your problem.

See if you can figure it out...

Bazant does not say ...

A direct extension of the problem above.

You depend completely on your (all too fallible) interpretation of what other people say. You have absolutely zero skills of your own to understand or skeptically critique the statements of other people.

Because, in every aspect of these discussions, the statements that you read from some unverified source, written by some unvetted person, is always "the only data that you know of".

So you actively, intentionally reject the data by the MOST expert people (NIST & the 100 engineers from academia & industry who participated), & instead choose to believe the LEAST qualified people: people who have zero expertise in the specific subjects under discussion.

Bazant does not say how much the fracturing would affect the resistance curve and he does not suggest that it could suddenly go to zero.

He did not say, so you have no tools to figure out what the right answer is.

Except to ask & uncritically accept & then repeat as your own personal gospel "what Tony says".

The exterior columns were typically W14x500. The flanges ares 17" wide and 3.5" thick. The Web is 2.19" thick and the column is 19" high.

19" high?

You really want to go with that?
 
Sure it was.

It is interesting that you and NIST have the interior completely collapsing on the east side first and then moving westward, but the east side exterior columns don't collapse until the entire interior is going, with the reason given that all of the the exterior columns were then unsupported and slender.

Why would the east side exterior have to wait for the west if they were already unsupported and slender seconds before?

You can not possibly be serious that this is either:

1. an accurate version of NIST's statements on the issue, or

2. some sort of mystery.

Can you, Tony?
 
No mention of what this thread is about for 3 pages. When faced with the logic and math that show the NIST theory is impossible the faithful change the subject.

The walk-off that is critical to the NIST collapse scenario is impossible because the sagging would shorten the floor beams more that they would expand lengthwise at 650oC. The thermal elongation would never exceed 4 3/4" [rounded off]. Prove this wrong or admit that it is true.

The formula for expansion is in the expansion spreadsheet:

The formula for sagging is in Tony's first post:
"The equation used to determine shortening is the same as that used by Zdenek Bazant in his 2002 paper where he uses u = L x (1 - COS of theta).

Here it would be Shortening = full length of beam x (1 - COS of the angle of sag)."

I had my own crazy stalker, who started leaving messages on my home town board to the effect that "did you know you have a traitor / gubbamint shill living in your midst?"

I have my own tech start up company (in addition to working for anoher start up). I approached my board of directors with this issue. "What happens if we start getting bombarded by truthers".

There was zero waffle on the issue. You can NOT bring this sort of distraction down on a start up company. Anyone looking at the company (to partner with or acquire) will back off just because of the controversy.

And especially because of the insanity, unreasoning quality of the participants.

Whenever Tony can't answer the arguments, he resorts to "I've told everyone who I am, but you remain anonymous" card.

It's the only card in his deck.

Why don't you stay out of it.

You haven't the knowledge to make an informed statement.

Allow me to illustrate: Without running back to him, in other words IMMEDIATELY explain where he gets the angle "theta".

I STRONGLY suspect that I know EXACTLY how Tony generated this table.

And if that is true, I know of a half dozen errors in his analysis. Mostly having to do with using linear, as opposed to non-linear, analysis.

Don't worry. That's just "gibberish to you".
 
+3 minutes. No response yet

Clocks ticking, C7.

Explain source of Theta please.
 
+9 minutes. No response yet

Clocks ticking, C7.

Explain source of Theta please.



PS. Or simply tell the truth & say, "I haven't the SLIGHTEST clue how he figures out "theta".

Don't worry. That's just "gibberish to you".

With a composite floor, sag cannot be determined (and is likely minimal) since the shear bolts would provide support even if the concrete has fractured and or the bolts yielded. There is also a lot of other miscellaneous construction that could have prevented sag in the floor beams. But facts do not get in the way of troofers on a mission.
 
+30 minutes. No response.

Clock stopped, C7.

Thanks for the demonstration, Chris.

It went exactly as I predicted (to myself).

Chris, you did notice that Tony added recently about 1.6" of additional movement of the seat with respect to the end of the girder, didn't you?

That would make this spreadsheet out of date. (In additional to, as yet unverified by anyone.)

Tony knows exactly where his numbers came from.

It's been 2 days since I asked him to lay out his analysis. He hasn't done anything yet.

Does it bother you in the slightest that he's not willing to explain his methods?

Nah, didn't think so.

But it bothers me.
 
tfk, Address the point.

My points have been made explicitly.

1. You stated above that Tony had listed his equations.

2. You are wrong, because his answer depends on the undefined quantity "theta".

3. If you are going to jump into a conversation about the equations, you should have the minimalist amount of knowledge about the issues.

4. So I asked you where he got theta.

5. You went silent.

6. Still no response from you as to how he calculated theta.

Now you're asking me to "address my point"???

If all the above isn't crystal clear to you, then you don't belong in merely the discussion, you don't belong in the building.

Is my new point clear enough for you now?
