Visible explosions in WTC7.The video you did not know exists...

Well maybe you get me wrong... I don't have a problem with the fact that it fell but with how suddenly it happened, many hours after it got hit by the North Tower, in 7 seconds and only after it cracked by itself from top to bottom before it fell as we see in the video. The building softens in front of our eyes and only then falls.

 

You're going to have to try again: WTC7 was not a tube construction.

 

It was actually. If not, then you tell me what it was and I shall show examples of fires in similar ones nevertheless. The truth is... there's been fires in all kinds of buildings. Some had to be demolished because repairs were too expensive but none collapsed by themselves. That's a fact that can be verified times and again.

 

So now I have to do your research for you? No ...

By the way: in the fire at Meridian plaza, all the steel portions of the building collapsed. Whoops.

 

You claimed WTC7 was not a tube structure. Asking me to prove what you said? Go ahead... prove what you said.

There were some local failures but overall the building retained its shape and continued standing. What do you mean by 'all the steel portions'? Define that. How can a building that looses 'all its steel portions' still be standing? The Meridian Plaza remained standing ffs.

 

Nope: you claimed the buildings were similar. Prove it.

The top portion of Meridian was steel. It completely collapsed.
The bottom portion was steel encased in concrete. That portion remained standing. The part that resembled WTC7? Gone.

 

Here's the positioning of columns in Building 7:



You clearly see a core made up by columns centered in the middle and a group of outer columns. A fcking tube structure by definition.

Where did you find that?

The building before the fire:



The building after the fire:





I don't see a fcking difference. Do you?

 

The top of the Meridian plaza was steel frame construction the bottom parts 'still standing' were steel re-enforced concrete...NOT steel framed.

 

I don't see how Meridian Plaza changed its shape after the fire:



The top of it is the same.

 

http://911research.wtc7.net/wtc/background/wtc7.html (truther site)

<WTC7> was of an entirely different architectural style than the other six buildings.

 

Windsor Madrid,sorry

 

Now we have a debunker quoting a truther site, just to try to prove me wrong! A premiere on the 9/11 forum! Guys you gotta have a look at this one...

But despite being a truther I didn't quote that site, even though it too says that WTC7 had core columns and perimeter columns so in other words a tube...

WTC7 was a tube structure, as even that site confirms. The 'architectural style' is something different than the structural style. The structural style was the same as in the Twin Towers and used the same load bearing method. Also the same type as the ones I showed earlier. They had fires, but none ever collapsed except Building 7.

So as requested by you, I showed you other buildings of the same structural type as WTC7 that had extensive fires but didn't collapse. So just as I said earlier, Building 7 is the only steel framed building in history to have collapsed because of fire, even though there were others of its type that had worse fires.

 

It sure was.

 

Again,it WASN'T just because of fire,why can't you accept the building was structurally damaged as well?

NOT in the way you're thinking,RWF

 

NIST says it's because of fire. So you believe NIST is wrong? They say it all started from a single column.

Whatever structural damage it received, there was a sudden uniform collapse after many hours. The lower sections showed no resistance as it went downwards. If the damage to the building caused by debris was not uniform then why was there such a uniform global collapse? Why do we see the building implode by itself before it starts the descent?

 

You keep making up your own 'facts' without sources. None of what you've posted is based in reality.

 

WTC1 and WTC2. There were no similar buildings to those three but here we are, another truther that doesn't know anything about the unique construction of the buildings. Go figure.

 

You sure? There were and still are. Post #175.

Ok, so the buildings that burned did not burn in reality? The collapse was uniform. Reality shows it in the videos. So were the cracked facades on all sides and the blown windows.

 

The NIST has always maintained that fire and strucural damage doomed WTC 7,besides for a study you don't think is true,you have no problem cherrypicking from it.

 

What study?

 

I see,It's going to be like that,now.

 

It's going to be like you TELL ME NOW WHICH ONE. Because I don't know what website you're talking about. What website?

 

So you think the ENTIRE WTC structure collapsed in 7 seconds? And Suddenly? Let's get you to take your blinders off for a moment.

Structural creaking, visible damage from the collapse of the Twin Towers, a visible bulge in the southwest corner, they even put a transit on the building.

And then you want to say the ENTIRE WTC7 structure collapsed in 7 seconds? What about the east penthouse that fell into the building prior to the roofline starting to descend? Why do you and others ALWAYS ignore these facts in order to come up with "in 6 or 7 seconds, the ENTIRE structure collpased"?

 

A few questions for you...

1. Is the term "tube in tube" the only characteristic you are applying to these buildings to deem them similar or did you actually research the construction of each?

That being said, please show me which of the buildings you posted above have the same characteristics as WTC7:

2. Which of the above structures was built upon and used an existing structure's (Con Ed substation) components?
3. Which of the above structures had cantilevered transfer girders as shown in the picture below?
4. Which of the above structures had 3 main truss assemblies (Trusses 1, 2, and 3, shown below)?

5. Which of the above structures were trapezoidal in shape and had an offset core which created longer floor spans between exterior and core columns on the north and east sides and shorter floor spans on the south and west sides?
6. Which of the above structures had a lateral load resisting system that comprised the exterior moment frame with a perimeter belt truss at Floors 22 through 24?
7. Which of the structures above had a perimeter belt truss between Floors 5 and 7, diaphragms at Floors 5 and 7 that transferred lateral wind loads to the core columns, and bracing in the core below Floor 7 that transferred lateral loads to the foundation? This system was not able to provide a secondary load path for gravity loads.
8. Which of the above structures, above floor 7, had no bracing, or other load redistribution mechanism, to transfer gravity loads between interior columns? The floor framing, which was the only load path between columns, could not redistribute loads between columns because the shear connections from the interior floor beams to columns were only designed for transferring vertical shear loads.
9. Which of the above structure's fires burned uncontested, without firefighters trying to put the fires out?

Are we to assume that your "tube in tube" moniker is all that it takes to make structures similar and to assumes that the outcome of an uncontested fire should have the same exact results for all structures you apply that "tube in tube" moniker to?

Not spinning anything. I didn't 'QUOTE' any website. And he can't answer which one.
