NIST's Fraudulent Report on the Collapse of WTC7 on 9/11 [W:2152,2510]

oz assumption is not the same in implied assertion.

yes I constantly have to correct debunkers, real pain in the ass.


in the land of oz if you disagree with oz assumption its non sense in the land of oz.

Why dont you explain to everyone the well known debunker version of burden of proof. you know for the record.

Don't feel alone. Ozeco's logic escapes me also. He insists that there cannot be a missing jolt in the North Tower, saying I am looking for it when the time for it to happen has passed. Bear in mind that I am looking for it at first floor impact, and the measurements of the Verinage demolitions in France show the deceleration we say should be there in a natural collapse. See https://www.youtube.com/watch?v=NiHeCjZlkr8&feature=kp

He also insists that the discovery of the pertinent structural features omitted in the NIST WTC 7 report collapse initiation analysis doesn't matter, as we can't know what the situation of the structure inside the building was, implying that the columns had moved etc. In other words, he supports the NIST fire did it theory without question and does not see a need to hold them accountable for omitting structural features which would have made their theory impossible.

What Ozeco is saying in both of these situations, where serious problems have been shown with the fire did it natural collapse theories for WTC 1 and WTC 7, does not make any sense. However, he continues to say it with no concern about the clear illogic of the argument he is making and actually places himself high on the list with regard to being logical relative to others. Just amazing.

Jeffrey Orling's logic is often similar. He somehow believes he can get a symmetric collapse of WTC 7 from an asymmetric failure of transfer trusses, that the structural feature omissions in the NIST WTC 7 report are not important, and that the missing jolt in the North Tower has no significance.

The illogical arguments used by these two, and others defending the "fire did it" theories, remind me of the adjectives Dan Rather used after seeing WTC 7's collapse "amazing, incredible, pick your word". I think if it was in their interest these guys would deny the sun is hot.

Tony your unwillingness or inability to follow simple logical reasoning is well established.

He insists that there cannot be a missing jolt in the North Tower, saying I am looking for it when the time for it to happen has passed...
Correct - that is your central error. With the proviso that I refer to the big jolt caused by a large falling object "landing" on something - your false starting assumption derived from your misapplication of Bazant's assumptions from Bazant & Zhou 2001-2. There would undoubtedly be many small jolts. The one you looked for could not exist for the simple reason that your starting premise - falling top block - is taken from an abstract model and does not represent what really happened in the actual event(s). You are not alone - many debunkers also are befuddled like you by false application of Bazantian assertions AND, unlike me, affeared of disagreeing with Bazant (or misuse of Bazant) despite the crime of lèse majesté having been removed from the statute Books. :lol:
Bear in mind that I am looking for it at first floor impact,...
Yes. Another perspective of the same error. You do not comprehend the essentially 3D nature of the cascade failure which comprised the "collapse initiation stage". Many debunker side researchers also fall for the trap. Look to the thousands of words wasted discussing "axial contact" and "tilt". When the simple reality is that for tilt to exist the opportunity for axial contact is gone. BTW "Missing Jolt" is merely a subset of the generic "axial contact" nonsense.
and the measurements of the Verinage demolitions in France show the deceleration we say should be there in a natural collapse.
your confusion is well documented across the internet:
The discussion is not about Verinage in France AND you seem to have the truther meme that there is some inherent difference between "natural collapse" and "CD initiated collapse". There ain't. Detailed explanations published several times. Drop your faith in false truther memes and put your engineering thinking into gear Tony. It ain't rocket science (either metaphorically or literally. ;))

Now you descend to misrepresentation:
He also insists that the discovery of the pertinent structural features omitted in the NIST WTC 7 report collapse initiation analysis doesn't matter,[SUP]1[/SUP] as we can't know what the situation of the structure inside the building was, implying that the columns had moved etc.[SUP]2[/SUP] In other words, he supports the NIST fire did it theory without question[SUP]3[/SUP] and does not see a need to hold them accountable for omitting structural features which would have made their theory impossible[SUP]4[/SUP] .
Four claims there Tony which are almost certainly deliberate lies - you have been correctly advised many times.
1 False. I have said that you have not shown that they do matter. And it is your burden of proof to support YOUR claim. NOT my burden to prove you wrong.
2 False - same comment as above. The argument has moved on but that starting assumption AFAIK still has not been addressed.
3 False and a common truther lie of false generalisation. I never rely on NIST arguments. Have not done so from my first days on the internet. Specifically to avoid truther tricks of "switching objectives". Bottom line for WTC7 is that there is sufficient evidence to explain the central locus of collapse initiation in the vicinity of Col 79. And your claims incorporate several dishonesties about the place of Girder Walkoff within that overall setting. Other posters here and elsewhere have identified those dishonesties. You have not corrected them. Until you do your claims re WTC7 remain unproven.
4 You cannot know what my attitude would be until and if you ever prove (i) That NIST was wrong; AND (ii) that it mattered.
What Ozeco is saying in both of these situations, where serious problems have been shown with the fire did it natural collapse theories for WTC 1 and WTC 7, does not make any sense.
No matter how many times you deliberately repeat that untruth it remains untrue. Serious problems have not been shown. You may fool gullible people Tony. You will not fool me -- or will not fool me unless you lift your game of deception several grades. And I doubt even then.
However, he continues to say it with no concern about the clear illogic of the argument he is making.
Claim is moot because the initial premise "clear illogic" is wrong.
Just amazing.
Stop being easily amazed. Start thinking like an engineer.

Jeffrey Orling's logic is often similar. He somehow believes he can get a symmetric collapse of WTC 7 from an asymmetric failure of transfer trusses, that the structural feature omissions in the NIST WTC 7 report are not important, and that the missing jolt in the North Tower has no significance.

I could carve up these leading lies by innuendo but I'll leave SanderO to look after his own. Your persistent false attribution of dishonesty on those who can out reason your nonsense does you no credit. I will not descend into the gutter with you.

Whatever is meant by "symmetrical collapse" hardly is significant. For one we can all see that there were distortions in the facade, the EPH and WPH preceded the descent of the curtain wall and attached moment frame. Over time these movements alone show a sequence and it's not a
symmetrical form. The movement moves from East to West and the curtain comes down and it developed a kink at around column 45 north of interior column line 73.

The debris was NOT confined to the building foot print but extended north across the street destroyed Fitterman Hall which had so much damage it had to be demolished.

The building's movement in the "release" phase ABSOLUTELY show a progress from East to West... hardly the sort of symmetry you suggest. This progression which occurred very rapidly... caused all mass/structure above to drop straight down... as it had lost axial coupling to the foundation... like kinking one leg out from a standing person carrying a heavy load who will likely fall down... especially if the remaining leg can support the entire load.

The rapid progression of failure propagated AWAY from the initial failure which appears to have been under the EPH (first section of the building to lose axial coupling to the foundation. As in a truss bridge failure... when a single member fails the failure propagates away from the initial member or joint which failed. This progression is rapid and the rate increases. The failure of the load transfer structures DID propagate to the perimeter which supported the moment frame of the facade and the attached curtain wall. Most of the north part of this moment frame was supported on cantilevers ans when they were displace there was nothing below to resist. The east and west sides of the perimeter had only 3 columns each directly coupled to the foundation. The rest of the columns above where on sloped columns of the wind shear braced frame.... these folded and failed to act like the bridges they were easily enabling the braced frame above to drop the 8 stories and then begin "crush up" from impact with the ground.

The building mass was about 250,000 tons and there was no lateral forces to influence the overwhelming downward force of gravity... so the entire mass came pretty much straight down... but not over the entire footprint at once!

The collapse resembles a CD because all CDs resemble a collapse... they all fall straight down. Ain't that a bitch!

So then there's no reason why a CD is ever required. Just set a building on fire and it should collapse pretty much straight down and globally after a few hours (7 or more?). It's cheaper than rigging it for a CD. And the precedent for this, besides the WTC collapses is ....?????? Still waiting for just one example, anywhere, any steel frame building of any reasonable height, anytime in history, any global collapse, anything close to what you describe for WTC7, doesn't even have to be anything close to free fall. Note I even allowed for as much flexibility as possible. The link please Mr. Expert? I'll stand corrected and change my mind about all 3 collapses if you can produce just one valid example.

but thats a lie as we can plainly see by the iron

thats a 90 degree tilt therefore still retains some axial loading abilities


the collision of 2 objects have to have a resulting jolt unless you are trying to defy ole newton again.

Show us a nice example of a collapse that looks like a demolition.


now you are going full debunker grammar nazi as well?

symmetrical collapse means it did not TIP OVER

how many more times does that have to be explained to you.
 
The discussion is not about Verinage in France AND you seem to have the truther meme that there is some inherent difference between "natural collapse" and "CD initiated collapse". There ain't. Detailed explanations published several times. Drop your faith in false truther memes and put your engineering thinking into gear Tony. It ain't rocket science (either metaphorically or literally. )

lets see your clips oz, show us the difference and stop gishing us with lip masterbation.

we are all waiting for your proof oz
 
It is. You aren't. Or more strictly your pretence that you do not understand (a) Scientific method OR para-legal procedure; AND (b) burden of proof is old hat. Most of us here have seen you repeat these silly distortions many times.
No matter how many times you repeat that nonense it will remain nonsense.
Implied assertion fails because conditional premise is false.

OOOOPSIE OZ DODGED ANOTHER ONE!


oz assumption is not the same in implied assertion.

yes I constantly have to correct debunkers, real pain in the ass.


in the land of oz if you disagree with oz assumption its non sense in the land of oz.

Why dont you explain to everyone the well known debunker version of burden of proof. you know for the record.


Explain burden of proof to us oz how does it work in the land of oz? then how does it compare to a us court?
 
What SanderO (Jeffrey Orling) either doesn't want to admit or fails to realize is, that it is just the interior which fails in the center and then quickly outward (as evidenced by the west penthouse failing east to west), and that this is how implosions are done.

The interior started failing in its center a split second before the outer core columns to apply an inward pressure. The east penthouse failure was a separate and distinct event high in the building, as evidenced by the east exterior not being deformed, no white dust emanating from the windows on the east side until the exterior came down, daylight only being visible in the top story windows, and a shock wave going from top to bottom.

If the failure had been an actual east to west interior progression the east side exterior columns would have been folding up first the way they do in the NIST model below.

NIST WTC 7 model exterior deformation.webp

In reality this did not happen. The entire exterior began falling simultaneously. The only explanation for it is the failure of eight stories of core columns starting in its center and pulling the exterior in on all faces causing a symmetrical exterior collapse and free fall over eight stories. That is why the demolition industry calls it an implosion, since the center is dropped slightly earlier to apply pressure to keep it together while it is falling.

Yes, fire has a long established reputation for destroying things. Steel performs poorly in fire which is why in high-rise structures so much effort goes into protecting the steel from heat - to allow the structure to remain stable long enough for occupants to evacuate and fire suppression efforts to commence. But fire is messy as we saw on 9/11/2001 where the burning 7 World Trade Center caused a cessation of rescue/recovery efforts in its vicinity, completely blocked 4 major streets for weeks, did hundreds of millions of dollars in damage to the Verizon Building and caused the total loss of Fiterman Hall.

So Tony, what caused the East Penthouse to fall?
 
FTFY

The specific error of logic is a false dichotomy based on a false generalisation.

The "opposite" of black is "not black" AND if it is "not black" does not prove it is "white" although "white" falls within the "set" of options. (or in this case "range" - it is a spread of possibilities - not a set of discrete values.)

"Elementary Logic For Truthers 000.5"


PS Tony Sz makes the same error of logic with this bit:
What SanderO ...either doesn't want to admit or fails to realize is, that it is just the interior which fails in the center and then quickly outward (as evidenced by the west penthouse failing east to west), and that this is how implosions are done.
EXCEPT that, in addition, he also frames it as a "lie by innuendo".

Fire has never caused a steel framed grid like superstructure, like that shown of WTC 7 below, to collapse through itself.

WTC 7 steel frame.webp

There is no chance WTC 7 came down due to a natural progressive east to west interior collapse as it would require hundreds of connections to break each second. The east to west collapse could not happen that fast naturally.

The North Tower itself had a large fire from the 11th to 19th floors in 1975 and there wasn't any fireproofing and nothing happened that would even remotely signify a collapse could occur.

I really have to wonder about those who claim that fire could have done what occurred to the three WTC buildings that came down on Sept. 11, 2001.

Right so again, if fire has such a reputation for destroying things and steel performs so poorly in fire, why ever bother with a CD, which takes weeks of planning and preparation and is quite costly? Why not just pour jet fuel into a building and set it on fire, no planning or preparation required and it should allegedly take just 7 hours for it to all come down in seconds? And I'm still waiting for that example that I also asked you to provide but you keep ducking, just like all the other defenders of the OCT. Why don't you just admit there is no such thing, it's that easy?
 
The east penthouse was eccentrically located in the northeast corner and contained heavy equipment, so it was brought into the building proper for stability prior to the full building being brought down.

So a bunch of heavy equipment falling adds stability?

Why was this additional stability necessary?
What arrested the fall of this equipment?
What about the heavy equipment in the West Penthouse?
Why isn't the fall of the EPH included as anything more than an incidental afterthought in your 24x8 free-fall symmetrical collapse scenario?
Doesn't the fact the EPH came down first, followed by the core, followed by the curtain wall by definition make the collapse of 7 World Trade not symmetrical? By my count that is 3 distinct stages.

There is no example of a building constructed like 7 World Trade Center and suffering damage like that suffered by 7 World Trade Center. Therefore there is no direct comparison. Uncontrolled high-rise fires in completely steel-framed, open-floor plan buildings are exceedingly rare - as I think we all would agree they should be. I can give plenty of examples of steel structures failing in fire but you have chosen to artificially define the terms in such a way as to pretend you win the argument rather than to determine the impact of fire on steel structures in the real world.

It doesn't sound like you understand what the term eccentrically located means, how it could cause a freefalling 400 foot tall upper section to rotate, and how bringing it down inside the building proper changed the dynamics. The success of the demolition needed the upper section to remain vertical during most of its fall.

The west penthouse was centered.

The symmetry was due to the symmetrical nature of the fall of the full building proper which included the core and immediately following, the exterior, as the core pulled it inward and down. The east penthouse fall was a separate and distinct event.

Almost every high rise over 40 stories built since the late 1960's is an open floor core and exterior type of construction and a number of them have had serious fires, including the North Tower (in 1975), with no indication whatsoever that they would collapse to the ground. This type of construction was first set forth by Fazular Khan in the early 1960's. See Fazlur Khan - Wikipedia, the free encyclopedia
