How were WTC core columns separated at the weld planes?

Max Photon, upon reading the previous posts I am not sure in which direction this thread is moving. Are we focusing on your original question:

How were WTC core columns separated at the weld planes?

It would seem to me that the question itself would go right over the heads of many of those reading. Judging by some of the comments, many people seem to be unaware that these columns were indeed separated along their original welds as can be seen in collections of photos of the rubble.

So many people commenting seem to be unaware as to how to refer to the photo collections publicly available to look for themselves at the ends of the core box column segments as they lie in the rubble. It is as if they have no capacity to look at the ends of these columns by themselves, but instead must refer to a government report for information on the subject.

I simply mentioned the 2 simple verifiable facts listed below and provided links to photo collections containing ample photos with which anyone can see these very columns for themselves. The facts were:

1) The large, large majority of core box column sections seen in the rubble are totally straight.

2) The large, large majority of core box column sections seen in the rubble have squared-off ends with clean breaks that are right along the original weld surfaces.


Consider the following responses.

This will turn the engineering world upside down!

I merely pointed out 2 observable and verifiable geometrical facts applicable to most every core box column we can see in the photos of the rubble. If you just look at these photos yourselves, these geometrical features are really hard to miss.

So why does rwgwinn talk about discovering something? Odd.


Consider the response of Gravy to statement #1:

I can't verify that, since

A) I haven't done a survey of those that are visible in photographs. Have you?

B) I don't know what portion of the total number of core column pieces are shown in their entirety in the photographs, with enough detail to make even preliminary damage/failure mode assessments. Do you?


Yes I have. It is difficult to post results here because I am not yet allowed to post pictures. It would take you a whole 20 minutes with the photos provided to get some preliminary, rough results by yourself. The numbers are so lopsided that it will become apparent to you rather quickly that the 2 statements are indeed correct.

It is as if Gravy would be incapable of using his own eyes to look at these pictures all by himself and forming views without "experts" telling him what he should see.

cmcaulif comments:

who knows if that is what he is actually claiming,

as if these 2 simple observable and verifiable facts are merely "claims" by me.

Max, he, too seems unable to simply look at collections of pictures all by himself.


So, Max. How, in your opinion, should we proceed to investigate your basic question about how the core column sections were separated from one another?

And, Max, how do you expect many of these people commenting to contribute intelligently to the conversation if they are incapable of looking at and grouping photos of the ends of these very columns as they lay in the rubble?

I fear since no expert seemed to explicitly address the core box column-to-column connections, with nobody to quote, many of the posters will find themselves at a total loss as to how we can study them.

No!

We asked you -- and I asked you very clearly -- why you think this indicates anything unusual.

You said in your first post that it was indicative of explosives (but edited it out after Gravy called you on it; tsk, tsk). This is wrong. Since then, you've very coyly avoided any answer whatsoever.

Of course, your site includes all kinds of nutty speculation about explosives... so why the evasion? Why edit out the phrase "apparent bomb damage" from your initial post? Why avoid the question?

You and Max should get along just fine, if this aversion to articulating your ideas is your typical behavior.

Well, it's possible -- I will give him some credit for attempting a hypothesis on his site, which is rarely if ever seen -- but he also seems to be trying to incorporate Max's ravings into his own story. Pretty strange behavior.

It also doesn't excuse him for his determined resistance to simple questions.
 
cmcaulif comments:

LOL, did I not agree with your simple observable and verifiable facts that you are alluding to here, and link to more photos of unbuckled columns failed at the splice?

Its pretty clear you think the obvious is true, and contrary to what you think, no one disagrees with the observed failure modes, what is unclear is why you think the observed failures should be considered unusual. You have been asked to explain your position several times and have not done so, so I honestly still don't know what you are claiming.

You are wrong. You have been repeatedly asked to justify the claims you make on your website. You have not attempted to do so.

Judging by some of the comments, many people seem to be unaware that these columns were indeed separated along their original welds as can be seen in collections of photos of the rubble.
You have repeatedly been asked why, in a collapse, the core columns should not have separated at their weakest points.

Please answer the question.


1) The large, large majority of core box column sections seen in the rubble are totally straight.

2) The large, large majority of core box column sections seen in the rubble have squared-off ends with clean breaks that are right along the original weld surfaces.
Your claim may be true, but you have provided no data to support it. I asked if you knew what percentage of the columns visible in the photos are of the whole. Do you know? Then simply present your data.

Yes I have. It is difficult to post results here because I am not yet allowed to post pictures.
We've all seen the pictures ad nauseum. Do not post them. If you have quantitive data to present, please present it now.


It is as if Gravy would be incapable of using his own eyes to look at these pictures all by himself and forming views without "experts" telling him what he should see.
My eyes are fine. I ask you again, so that you can't say you didn't see the question:

In a collapse, would the core columns likely separate at their weakest points? Yes or no?

as if these 2 simple observable and verifiable facts are merely "claims" by me.
Let's say you're right. In what way would that support your claim of "apparent explosive use?" Please include all blast effects that would be expected to be found on the steel according to the type of explosive you believe was used. If you can't do that, then your hypothesis is fatally flawed. If you think you can do it, then back your claims with verifiable evidence and science. For example, present close-up photos of structural steel similarly damaged by the type of explosives you think were used. Present studies and expert opinions that back your claims. Your speculation comes from ignorance and is easily refutable. Reality will not adjust to you. You'll have to accommodate it. This is a great place to start that process. You may not be aware that you've already dealt with experts here.

You have not distinguished yourself from the dime-a-dozen conspiracists we see all the time, who argue from ignorance. If you think you can step up and defend your position with relevant facts, then get to it. If not, then you must reconsider your position.

Clear enough, Major Tom?
 
No!

Ground control to Major Tom: don't go drifting off on us.

You said in your first post that it was indicative of explosives (but edited it out after Gravy called you on it; tsk, tsk). This is wrong. Since then, you've very coyly avoided any answer whatsoever.
I don't know if he edited the "apparent explosives use" out. In my response to his first post I was quoting his website. If that phrase appeared in his post, I didn't see it.
 
It looks like Max may have ran screaming from yet another thread.
I don't see any response after his cry of rule 11.

Mark, you've summed up the twoofers' problem very succinctly. They must reconsider their position, which is...

That a gigantic, mathematically impossible cabal originating in the inner circle of the Bush administration...

A cabal that spans several branches of government, including the military, and various private industries...

Blew up the Twin Towers of the World Trade Center and part of the Pentagon...

Using either imaginary beam weapons that won't exist on this planet for decades or commercial airliners obtained, through unknown means, with the cooperation of the Boeing Corporation and the relevant airline companies...

For the purpose of starting wars with Afghanistan and Iraq (although the cabal decided not to make any of the fictitious hijackers Afghanis or Iraqis)...

In order NOT to build a gas pipeline through Afganistan and NOT to steal oil from Iraq (has anyone ever figured out how to "steal" oil from an entire country?)...

Wars that had the effect of transforming Republican majorities in both houses of the U.S. Congress into Democratic majorities and leaving Bush the lamest of lame-duck Presidents.

This hopeless farrago of sheer idiocy is their "position." The "conspiracy" is an interminable shaggy dog story stumbling on in search of a punchline. The most unprecedented crime in history turns out to have had no discernible motive.

And we bother to debate them on the minutiae of their house of cards?!
 
You have repeatedly been asked why, in a collapse, the core columns should not have separated at their weakest points.

Please answer the question.

That's something I never understood. I've never even asked myself the question as to why they would break at those points. It seems so, so obvious to anyone with a basic knowledge in... er... well... ANYTHING, that I really don't understand why anybody would have a problem with it.

Oh, well.

Oh, well.
It's strange isn't it, that a failure mode would incorporate the weakest points of a structure :rolleyes:

What alot of the troofers don't understand is basic metallurgy or engineering. I love the term "heat-stress". I have never heard a metallurgist or stress engineer ever use this "term". I have 10 years plus experience and 7 of those in metallurgical failure investigation and I've never used it let alone heard of it. Now stress caused by heating (eg: phase transformation, increase in volume etc) does occur but not in the context that it is being used by the OP. I love the ignorant trying to sound "scientificky" but all they do is show their ignorance by making up terms. :)

Failure along welds caused by shear stress often looks very smooth. It's nothing out of the ordinary if you understand what you are looking at and why.

Around Here, We often usethe phrase "Thermal stress", which is well-known as shorthand for "Stress due to differential expansion and contraction under various thermal transition conditions" which is a bit of a mouthful...

This is especially true if the welds are just tacck welds to hold things in alignment while you put in the fishplates and bolts...

Thermal stress is the term I'm used to hearing often as well, although I seem to recall some of my profs. in Uni using "heat induced stress" back in the '70's

Gotta google "fishplate". Is that what you'd call a "mending plate" in carpentry?
 
Max disclosure

Hi everyone,

Before continuing with this thread's discussion, I thought I would briefly describe my relationship to Major Tom, in the spirit of full disclosure.

After doing some 911 investigation of my own, I joined STJ911 earlier this year, to discuss the notion of thermite having multiple uses on 911. I focused on the perimeter system, and spend zero time on the core.

My ideas found zero support at STJ911.


Major Tom was already at STJ911 before I arrived. I believe he was trying to point out to Jones and the Cutters that there was no evidence of thermite-cut core columns, and that MColombo's main point that all the core columns were separated at the weld planes should have been sufficient to extinguish that notion. I don't think Major Tom got very far.


Anyway, just shortly before I got thrown out of STJ911, I believe some of my MILDEC ideas, and some of the perimeter heat-weakening ideas caught Major Tom's attention.

The day after I got tossed I set up my crappy little site (sorry Universe).

Shortly after, Major Tom independently set up his site to present photographic evidence.

I email him occasionally to give him input on making his site more usable.

I gave him permission to post some of my emails - for example, how to download video from the internet, and view it frame by frame.

Major Tom also links to my site.


That's really the extent of it.

Our ideas are completely independent of each other's, and in fact, I am not very clear on Major Tom's positions, so I do not even know what overlap exists, or the major differences.

But we shall see!


Welcome Major Tom. Nice to have you aboard.


Cheers everyone,

Max

The core question on the core question

So, Max. How, in your opinion, should we proceed to investigate your basic question about how the core column sections were separated from one another?


We need to answer:

How strong were the welds?


Max


* * *
 
Max asks: How strong were the welds?

Core box column segments are seen in photos of the rubble in lengths of 36 feet, more or less, or multiples thereof.

For example, you will see many sections that are about 36 ft., you will see some that are about 72 (2x36) ft, more or less, and you will see a few that are 108 ft (3x36).

This is because many of these box column-to-column welds held very, very well. They held so well that you won't even know there is a weld in the column unless you know where to look.

Some of these were great welds: For example, many people are aware that to the west of the North Tower, in the rubble, there are these core box columns that are driven into the ground like lances, just sticking into the ground. You'll see some in the picture at the following link

h t tp://w ww.sharpprintinginc.com/911/index.php?module=photoalbum&PHPWS_Album_id=1&PHPWS_Photo_op=view&PHPWS_Photo_id=337

Do you see the largest core box column section sticking out of the earth like a javelin at the bottom of the picture?

That piece is actually 3 core box column sections held together by excellent welds. You would never know that these are welded pieces unless you know how to spot it. And please notice that after being hurled like a javelin and sticking into the ground like it did, it is totally straight.

Max, these are tough little puppies.

If I could post pictures I could show some examples of welds that held so well you would never know it is actually a weld unless you know where to look.

Max, please look at the photo a the link below.

h t tp://w w w.s harpprintinginc.com/911/index.php?module=photoalbum&PHPWS_Album_id=16&PHPWS_Photo_op=view&PHPWS_Photo_id=27

This is a photo looking down onto the North Tower "spire". Do you see the pair of core columns falling away to the left? Do you see how their ends are trailing smoke? A general estimation is that the smoking ends were original from the 50th to 60th floors, well away from the original fires.

So why do you think they are trailing smoke?

A note to cmcaulif: Your right. I stand corrected.
 
With all total welds in the core and human nature being what it is. What percentage of all those welds would be good and what percentage would be not so good?
