A Structural Reevaluation of the Collapse of World Trade Center 7

[Jefe's Dope]

This should prove interesting. The thread that is.

The principal conclusion of our study is that fire did not cause the collapse of WTC 7 on 9/11, contrary to the conclusions of NIST and private engineering firms that studied the collapse. The secondary conclusion of our study is that the collapse of WTC 7 was a global failure involving the near-simultaneous failure of every column in the building.

Saw that. Not new news to us tin hat wearers. There was a clip of Pres Bush saying they had to take down WTC 7 that was quickly scrubbed from all sources. Also, the buying and insurance claim on the bldg. is simply astronomical. Follow the $$$.

Anyway, would be awesome if we could find those scum responsible and hang them.

It is our conclusion that the collapse of WTC 7 was a global failure involving the near-
simultaneous failure of all columns in the building and not a progressive collapse involving the sequential failure of columns throughout the building.
Despite simulating a number of hypothetical scenarios, we were unable to identify any progressive sequence of failures that could have taken place on September 11, 2001, and caused a total collapse of the building, let alone the observed straight-down collapse with approximately 2.5 seconds of free fall and minimal differential movement of the exterior.

Pretty damning.

Although I have not vetted the sources nor the commission.

The steel members gave under the burning of 20,000+ gallons of Jet-A (up to 1500deg), something no engineer imagined, and the floors pancaked.

Why it has to be a conspiracy beyond Alqueda fanatics is something for you and your therapist to discuss.

Bldg 7 was melted by jet fuel?

You'd have to hang the founders and rulers of an entire Nation/State. The hijackers were just manipulated tools.

With two out of three names listed on the cover page being Chinese (I think), makes me wonder how much of the funding for this came from across the ocean. WTC 7 has always been a little perplexing though.

Because that bunch of nit wits didnt have the brains to plan and pull it off by them selves. As rtb mentioned 'Building 7". It just fell down by itself, I suppose.

As a structral engineer who does forensic studies of building failures everyday, this conclusion is not acceptable or possible. .."was a global failure involving the near-simultaneous failure of every column in the building." A building fails one member at a time until the remaining structure is overloaded. Member failures sequences may happen quickly but something has to fail first that start the global failure.

Not to punch holes in this report, since it took 4 years, but there is only one registered structural engineer in the authors list, the first person, and the 2nd is a bridge engineer and the 3rd isn't even a registered professional engineer.

Plus understand this is building 7. The shortest of the 3 buildings to collapse. This is not the 2 tall towers.

 

[HMRamateur]

I remember watching the news when I was younger, and they had claimed that building 7 was actually scheduled for demolition that day, that's why it fell without being hit. I always thought that was weird that they would say that, and in a way that was basically like saying "this is the reason, don't worry about this building anymore". This was on the news the same day as the attack as well.

Always wondered why they would claim that.

 

[brianf]

wondering (not judging)..

The people that believe that WT7 was a controlled demo is that because:

you believe 9/11 was a inside /govt/cia etc set up

wt7 was a scapegoat for $

if so what would that building cover up that could not be taken care of a few days before.

I don’t think there were causalities from 7 collapse. which means they only destroyed "material" but the secretes were still able to get out via human leaks

Thanks

 

[Maggot]

Here's a little known, or at least seldom allowed to be published, tidbit. The fellow who owned the WTC's collected 3 Billion dollars insurance. Then, he tried to sue United and American airlines for an additional 3 Billion. Guess what his name was.

Isn’t that the point of the article? Aren’t you agreeing with them that something’s fishy?

I am disagreeing with the structural failure mode of this new paper. Thier conclusion is not valid in a scientific study response.
Gibbs rule 39. There is no such thing as a coincidence.
All the columns failing at the same time would have to be a coincidence. They must pin point one member that failed first then the next then the next.... not 71 columns at the same time. All these columns failing at the same time is soooo statistically unlikely I cannot accept it.

It’s almost like they are saying it was a controlled explosion (done on purpose) and didn’t just happen all by its lonesome.

Would make sense. If the building was scheduled for demo (needs verified it was sheduled) that day or week what better way to get the government to pay for the cleanup.

That’s the whole point of the study. They don’t agree with the accepted causation. Slowly and surely it’s sinking in.
Glad to have you.

We continue to bow to their kings, send them billions of dollars for oil, and then take an bit of that money back so they can buy fancy weapons and destabilize the region.

Absolutely nothing. But we are holding their hands through killing everyone in Yemen right now

Just like that video of the firefighters running down the street and yelling “they’re going to blow it”?

I’m not a structural engineer, nor do I play one on tv, but I’m willing to bet that you could watch 100 videos of buildings being imploded and you would not see a bit of difference when #7 was imploded....I mean umm

Well, any illusions I may have had that Muslim Arabs can build and sustain a Republican style government were lost decades ago. There seems to be two options: friendish petro-dictator, or Islamofascist crazies trying to kill us. Looking for the good guy is what got us into trouble. They’re all villains. Support the leader who doesn’t want to attack us. He’s the only one who can beat down all his people who do.

So, it isn’t kewl to be a 9/11 conspiracy theorist about the twin towers anymore? BUT, being a building #7 conspiracy theorist is where it’s at?
This is just as much bullshit as wearing masks is dangerous....the CDC requires everyone to wear masks. Yes the government lies, and for retarded reasons, because it’s full of idiots (just like out here).

Oh man, there's was some stupidity out of University of Alaska about wtc7. It was just as much bullshit as this is.

Next step in this is someone's about to tell me that a missile hit the Pentagon.

The nose of the plane went through the window of my former XO‘s (Cpt. Dolan) office. My girlfriend down the street from The Pentagon, at WSB, watched the plane come in and hit.

all joking aside, i still wondering about these questions, i posted yesterday

if we believe the collapse was caused by demo (right or wrong)...what could that mean other then the govt may have lied to us about demoing a building etc

 

[FS1]

Conspiracies abound. I personally will remain skeptical of anything Govt tells me until I see people swinging from ropes for the Coup against our President. Until then nothing is real and anything is possible.

It saddens me to have to think like that. But I am a product of the current environment. You argue over potential truths that will possibly never be known.

thats to many layers of tin foil lol

Watch the videos. They look the same to me. No way all the steel melted at the same time and if it didnt then the top would have tilted and fell to one side, not straight down. But believe what you wish, trust your government, they know whats best for you.

Talk to me about the modulus of steel and the stress strain curve dependent on temperature, then let's discuss live loads, dead loads, and impact loading.

We can also talk about designed failure paths too.

Feel free to reference sections out of the AISC Manual of Steel Construction: Load and Resistance Factor Design Manual, and then i can follow along at home. Thanks.

 

[brianf]

100 stories tall, 1 city block wide is not the same as 25 stories

then add in the planes which i hope we all agree hit the buildings

toss in the exterior of the towers were the load beating structures as well not just a facade like all those videos

there has to a limit on this thread lol

im really trying but my day job is under control for the morning

secondary business is making headway, although its at a snails pace lol

i think 9/11 gets me going because of its proximity to where i live and knowing 2 people who were port authority cops

the corona virus gets me because everyone wants to play Monday morning QB (we all do its human nature)

if i had time i would make a daily agree or disagree thread with what the govt has done with wuhan

force everyone to answer the new questions everyday like the president/govt has to...no days off

then tree diagram it out with statistics and models and see if they would have faired better

i did this in college for my economics minor, was really funny to watch people start down the rabbit hole and not get out

remember reading the "choose your own adventure books as kids"

i bet most of the posters are the ones who would go back and choose differently if they didnt like outcome...not the way it works in real life


i must say, this thread has stayed cordial and on OP path so its enjoyable to play around
