'What about building 7'?

Not open for further replies.
The funny thing is how it got from being painted on the beams to falling on cars all over. NWO needs to work on their adhesives...

Didn't Chris Sarns say it was in the ceiling tiles ? Maybe it was in the gypsum board ?

That was Jim Hoffman iirc. Something like 2 million ceiling tiles rigged with nanothermite explosives (or something) and wireless detonators.

You cannot make this up :)

eta: Yep

The best thing is that it doesn't need a heat source to ignite, just contact with car paint.

What is it exactly that you're expecting me to respond to?


This:

"The top of the columns at floor 16 were fixed in the global x- and y- directions, to prevent lateral displacements..."

Note, only the top and bottoms were fixed in the x- and y- directions, the rest of the columns could move in all directions.

Where does it say top AND bottom?
They were free in the z axis.

Just before the bit that I quoted.

…Here, let me read out p484 NCSTAR 1-9 for ya:

"Displacement Boundary Conditions

The column nodes at the base of the 16 story model were fully fixed to model the rigidity of the grillage and foundation (Chapter 2). The top of the columns at Floor 16 were fixed in the global x- and ydirections, to prevent lateral displacements, and were free in the global z-direction, to allow vertical displacement of the columns in response to gravity loads and thermal expansion. The purpose of the ANSYS model was to simulate the accumulation of local damages and failures up to the initiation of overall global collapse due to fire. The building was not expected to displace significantly in the x- and y-directions outside of the floors with no fire and there was no interaction between adjacent columns for relatively small motions in the z-direction, due to limited load re-distribution mechanisms."​

No other Displacement Boundary Conditions are mentioned, and since they explicitly state those for the bottom and the top of the 16-story assembly, I am sure you will agree with what I implied initially: the 16-story FEA model DOES reflect the deformations and displacements in all directions that reality necessarily must have seen - on all floors except the very top and the very bottom. It would help your credibility to admit that the model does indeed reflect movement of all nodes on all the relevant floors (5-13 at least) in all spatial directions. If you go on denying or ignoring this FACT, this would serve to further undermine your credibility.


Oystein was also keen for you to respond.

I don't agree at all that all the nodes and connections in the model experienced movement in all directions that reality would have seen. If that were the case, the floor beam would have broken its connection at the east end also and NISTs original 5.5" claim would have lost the best part of an inch.
Surely you aren't asserting that in reality this connection wouldn't fail?
 
Um. No. Just no. You do not need to cut both the hot and neutral, just the hot and have contact with a ground path .............................


Small nit pick. The neutral will also create arcing if it's broken and connected to a load. Under load it carries to same amount of current as the hot. ;)
 
There is no chance that the WTC 7 electrical power system was designed so that the generators could have been able to come on when power was intentionally cut off.

Don't you ever get tired of being wrong? What makes you think electrical power was shut off to building 7 prior to the tower collapses?

If it was, that really throws a wrench into Barry Jennings account.

Perhaps you misunderstand, Gerry. I'm merely drawing your attention to posts requiring your response. You've responded, so now other interested parties in this thread can respond to you, and I can observe and see whether it plays out in a similar manner to the way it usually does.

Personally, I don't give a monkey's about the minutiae. I'm interested in the motives and methods of truthers*, not in the piddling trivia they choose to focus on.



*Mark F posted this in the Niels Harrit thread, and it's worth reproducing here:

The emphasis on Building 7 came about after the utter failure to convince the public of CD at the Twin Towers, missiles at the Pentagon and switched/shot down planes at Shanksville. Building 7 is the CT's Alamo.

The evidences for what happened to the Towers, at the Pentagon and at Shanksville are all pretty open, obvious and abundant. Building 7 however was a structure few people who did not work there or live nearby would have heard of or cared about, and because no one was killed/injured there and it was (understandably) overshadowed by other events 7 was largely ignored.

There is nothing CT loves more than a vacuum and the lack of information and interest in Building 7 created a wonderful void the CT community could fill with their own narrative.

What continues to confound me is reading the comments from what appear to be intelligent people who are educated and believe that 9/11 was an inside job, that the towers were all taken down with CD and other fantastical beliefs. I realize that there is a distrust of gov because of the constant spinning and PR... and some outright lying.... such as the WMDs in Iraq. But how does not dismiss the fact that the US policies have given rise in many places and cases to insurgencies and what amounts to "blow back" and 9/11 was the mother of all blow back and it was entirely possibly. These people argue that it is impossible for the NSS not to have known the attack was coming, not to be able to stop in in progress, that it was impossible to fly the planes as they were into the targets that they hit and so on. Intelligent people simply acting like irrational idiots. It's science denial... and the inside job conspiracy makes no sense not to mention that not a single person has leaked yet this inside job must have involved hundreds if not thousands of actors in a completely un rehearsed never before done operation of the complexity that would boggle the mind. Ironically it was a very low tech attack that our bloated NSS was unable to do a thing about... and we have been living with a false sense of "security".
 
This was your claim,

p484 NCSTAR 1-9
Only failure modes in the East side of the building were modeled and the columns in the model were fixed in the x-y axis to prevent any lateral displacement.

This is the counter claim,


Seriously? :eye-poppi Did you hope I would not open the report and read for myself??



Seriously??? :eek::eek:You really can't read, can you? Here, let me read out p484 NCSTAR 1-9 for ya:

And your response was,

Surely you aren't asserting that in reality this connection wouldn't fail?

So do you still think the columns in the model were fixed in the x- and y- directions along their entire height?
 
He can't see the difference between "bottom totally fixed and top fixed in x-y, others free" and "they were all fixed x-y".

He has just seen some words and has leaped to a false conclusion.
 
First, the likelihood of the circumstances needed for resistive conductive items being randomly connected to a hot wire and conductive path to ground on ten different floors is exceedingly low, and now you need the generators to come on when we know power was intentionally cut in WTC 7 a half hour before the North Tower collapsed.

.

the LAN cable is a ground conductive path to ground. The chassis of the circuit borads is a conductive path to ground, a telephone line is a conducdive path to ground (oh that one could have told the squirrel that immolated himself jumping from the power lines hot(where he was safe to the telephone line just below the power line, on the street in front of my ex's parents house. We saw it happen and also heard the telephone chime,,, once, then it was dead along with the squirrel).

In 2001 there still would have been CRT monitors on office desks. CRTs routinely used 20KV supplies on the screen and smashing one was quite capable of starting a fire.

Then there is the hot material from WTC 1 which no one has shown any reason to believe could not reach WTC7.

However, in our countries it is quite within one's right to believe whatever fiction one wishes to believe, including thermite dust raining down and igniting office and vehicle fires and arson spooks entering office buildings.

You have missed the context of my question.
You had previously claimed "Only failure modes in the East side of the building were modeled and the columns in the model were fixed in the x-y axis to prevent any lateral displacement", referencing p484 NCSTAR 1-9. I pointed out that your own reference explains that the columns were fixed in x- and y-directions only on top and bottom, and free to move in x- and y-directions everywhere in between, and that we can thus expect that all nodes in between WOULD move in x- and y- (and also z-) directions as fires heated elements differentially.

I said that this would happen in the NIST model as well as in reality.

I merely wanted you to acknowledge explicitly that all nodes between top and bottom were free to move laterally, both in the NIST model and in reality. You seem to previously have denied that, for example, col 79 at the 13th floor level might have moved laterally in the model and/or in reality.
Since we do not know how far that node had moved east (we only know that it jhad moved east in the model) we cannot know whether 5.5" of expansion of the beam framing into the girder nearest to col 79 would have sufficed to make the girder walk off - but NIST tells us it did walk off. By acknowledging that the node was free to move laterally, which includes the possibility of it moving more than 3/4", you'd remove your claim that walk-off was impossible.



Now you make additional claim about how other nodes would react to other stresses - we can look into that later. Please answer my question, first, in context:
http://www.internationalskeptics.com/forums/showthread.php?p=10519838#post10519838



I had also asked you:


Are you involved in the FEA project announced by AE911Truth as part of their "ambitious agenda for 2015"? If so, in what capacity? If not, do you know who is leading this effort, who is participating?
 
There is no chance that the WTC 7 electrical power system was designed so that the generators could have been able to come on when power was intentionally cut off.

That power shutoff system, and when the generators would and would not come on line, would have been tested when the building was being certified for occupancy.

Naturally you can cite the requirements for this?

I know where you pulled this from........:rolleyes:

The Gen-sets would not know the difference between an intentional loss or otherwise. They would need to be manually switched.

I'll gladly retract this if you show some proof of your statement.

I'll wait................
 
Ok I'm confused.

How did the gypsum dust put out or prevent the fires in WTC 7 almost 350 feet away but allow vehicles almost right beside the buildings to burn? :confused:

A few months ago I bought a thermocoupleWP on Ebay, not because I needed one but because I've always wanted one and it was dirt cheap.

We also have a wood stove. This was glowing (not flaming) nicely when we went to bed around midnight. Just now - 12 hours later - it seemed totally out, but I discovered glowing embers when I scooped out surplus ash.

The thermocouple measured the temperature of one of those embers at nearly 500°C

The intensity and sheer mass of the WTC1 fires, and the lack of time to cool, would certainly ensure that any hot remains from the N side fire zone would be way above the auto ignition temperature of paper.

Are you saying you actually think the north side of the North Tower where poor Edna Cintron was standing in the hole was still that hot when the building collapsed? If so, it doesn't sound like you have thought this through very thoroughly.
