Ok course but again, quantify the 'complex" events to account for the rapid descents. You again are making assumptions, like NIST did that collapse was a foregone conclusion, without taking into account the complex mass involved.
Again you give a simple answer that defies explanation. Of course you say "The upper section hit the floors and sheared the connections." Your highlighted section is not giving the answer.
You still fail to consider that the time required for all of these failures would not be in the 12-15 second range, You fail to account for the 2 masses colliding and that when this happens there would be a noticeable jolt, and hesitation as ech and every subsequent connection is overcome.
And you still fail to explain this by posting a totally non explanation from NIST!?
It is you who has been saying that the NIST report is correct and yet you post nothing but assumptions and repeat the NIST flawed theory?
It discusses estimated, conservative loads asshole! It does not explain how the **** these loads were able to overcome the equal, and opposite resistive loads by the lower, in the short collapse time!
Bullshit, this is their assumption based on a guess, with no figures to substantiate it.
You want to insist that 2 1/4 mile long towers fell in such short collapse times because of localized failure due because of an unsubstantiated guess that fireproofing was dialoged, because they did a test of this theory with a ******* shotgun?
Thus causing the rapid collapses? You're a ******* loon, and when I ask you to post how you come to this conclusion besides all the speculative guessing that NIST did, you post even more speculative guess work!! Brilliant!
I've already explained this before. Now it's up to you to validate that unprotected steel the likes that are used in buildings like the WTC and others , can explode into themselves in just short of FF acceleration, and maybe you can explain why NIST themselves mentioned that the failed towers fell "essentially at FF"?
Read my answer to you attempt at being evasive.
It explains nothing!
That's right localized failyre, that has not come close to being proven that it would automatically lead to a complete and total failure, with "essentially FF" (NIST)
Localized failure that had to advance a collapse sequence through the rest of the undamaged lower, more robust structure.
No asshole, I asked you to consider what I mentioned, and to show where NIST considers it as well, and you have failed!
Again justify how this automatically means total building collapse in such rapid times. Why do you not account for the mass of the lower? Where are your NIST calculations?
So how long should it take for these angle/floor truss connections to fail? And why did the lower building not halt the collapse fronts?
And depending on the size (mass) of said football player, it might take a few tries to bust through the ******* door you idiot!
Tell me, would it be faster to go through an open door then a closed one?
Can you, or this football player walk through the closed door in the same amount of time as if it was ******* open?
Think about that you ******* moron!
This is my ******* point. Things take time, these buildings had tons of ******* heavy steel components, and concrete. Now you actually believe it logical to assume that like the analogy you presented above, that a smaller damaged mass, will overcome the larger one with all these connections in the short amount of time witnessed?
Explain how this is so, but in your explanation do not fail to consider the mass of resistance below the collapse front like you've been doing.
Again the buildings were designed to withstand the impacts of airliners. They did. Even NIST admitted they did a good job of that, and base their collapse initiation on the ******* fires that they have not been able to explain, the intense heat that IS necessary to overcome steels properties.
This is no game I am stating historical facts, and use the buildings designers own statements, and NIST report against your failed logic, that is not based on any real world facts.
Yeah idiot...do you not understand this concept, Is it not prudent to do?
STRUCTUREmag - Structural Engineering Magazine, Tradeshow: Fireproofing Steel Structures
So you can take your "conduction" bullshit and try it elsewhere. You need to learn a few things before parroting your garbage from other sources that have no clue what they are talking about.
Yeah, they fireproof steel in case OTHER things catch fire.
No where has a building fire been so hot as to cause a total 12-15 second global collapse of a hirise....NO WHERE!Office fires do not approach the heat required to cause this kind of damage that will leave 1500 degree rubble piles underneath them.
Go ahead and post a link to where you have seen this, and I'll post the Cardington Fire Tests Results. You are a mammoth idiot
How about one of my examples?
Take a semi truck and trailer. Stack it up vertically.... Now take VW and hoist it up 12 feet
above the cab, so it gets a running start like NIST has said the WTC tops had...
Do you think the semi will be crushed all the way down in mere seconds?
Actually replace the VW with an identical semi truck and do the same thing.. Do you still expect the lower semi truck to just be squished, and the top one have so much PE that it will totally pulverize the lower one? In mere seconds???
I don't know how ******* retarded you really are, but the answer to most rational and intuitive people would be NO! Absolutely not.
But yet this is the flawed thinking that you present.
The lower did not just consist of the damned truss/angle supports in a few spots. This is but a small part of the entire ******* building.
Fire takes time to damage steel to it's failure point, even if loaded, it takes time. We can expect to see its slow demise, and start to creep, then expect to see it fail towards
that part.
Each subsequent lower floor, complete with those angle/supports presented another obstacle to the failed, falling part. **** common sense will tell anyone with the capacity to think, that these "collapses" should have taken much longer then what was observed.
