And of course he needs to prove that a mechanism exists that can survive an aircraft impact and massive fire for an hour and still leave the explosives viable.
In the slo-mo, you can see the right wall of the top section break completely loose after having dropped less than it's own length; from then on, it descends at free fall acceleration. It reaches the ground first, but barely ahead of the internal collapse front.
The core and the left wall zig-zag down with some delay after all floors have rushed down, while the right wall is pushed outwards by falling floors, and its lower habe topples over.
This simple model shows a number of features of the real WTC collapses:
- Floors falling ahead of columns
- Floors collapsing with an acceleration not far from g
- Wall peeling and toppling outwards
- Core failing last

You ignore lots of things, and here are a number of them.
Bazant wrote a series of papers. We have discussed four of them at length in this forum. Of these four, the first one was the one that NIST used as reference, and the second one is the one that talks about crush directions.
The first paper doesn't directly apply to the real collapse either. Bazant's strategy was: if it fails under the most favourable condition for it not to fail, it fails under any conditions.
Then he proves that it would fail even under the most favourable condition, and rests his case. He doesn't need to contemplate the real collapse case, because it's included under the any.
That's what NIST agreed with. NIST wasn't concerned with crush direction.
If it existed you would post it just to prove that it does exist, and I am wrong. You would never pass up the chance to prove I'm wrong.You've not searched for the experiment I posted.
Are welders engineers?Nist does explain collapse, it's right here:

Cascade failure? Is this your clever way of saying "pancake collapse"? That theory has already been abandoned.And just as you asked for: It describes the cascade failure that occurred after collapse initiation.
Just ranting, eh?
We know enough. Engineers have designed buildings the world over using the findings from NIST.
The 9/11 CR wasn't tasked with technical stuff.
Your rantings don't change anything. The truth is what it is.
The pancake theory was abandoned. There is no point discussing it.No it hasn't. FEMA presented a pancake theory of collapse initiation. NIST dismissed that theory. FEMA also presented a pancake theory of collapse progression. That one is still in vigour.
ETA: NIST even makes a quick mention to floors pancaking in NCSTAR1, when they analyse the failure modes in the recovered steel.
Reversing the burden of proof. Your claim, your burden.Did anyone bother doing an experiment to try to confirm their theories?

Proposal for an experiment to prove Cole wrong, Tomorrow when I have time, I will drop my 4 pound shop hammer, on a Mountain Due can.
Then I will Drop My 8 pound short handle sledge hammer on an identical can.
According to Cole and FF the motion and damage to the can should be exactly the same, since energy values and Scale do not matter.
What do you think the results will be?
NIST was supposed to investigate the collapses. They had the burden to investigate. They made claims. They have the burden of proof to prove those claims. In some cases, they have failed to provide the necessary proof.Reversing the burden of proof. Your claim, your burden.

What exactly did you mean when you claimed you never proposed CD and were embarrassed when your claims of CD were highlighted right here?
I am actually curious as to why you thought you would get away with that attempted dissemblance.
Are welders engineers?
Where is the peer review of the paper you have submitted?
Will the directions of net forces be similar? Yes. Will the accelerations be similar? Yes. Will the direction of net force be similar? Yes.Force will double with the 8 pound.
I asked for a peer review of the welder paper. Have you submitted that?Are crackpots forensic analysts?

My first and last post in this thread.
Really?
Did anyone bother doing an experiment to try to confirm their theories?
Do they need to talk about the hijackers? No. Do they need to talk about flight 93 or the Pentagon? No.AE911 doesn't even acknowledge half of 9/11.
They don't even talk about 50% of it.
Unreal.
Of all the absurd statements you've made, that may be the most laughable.
Are you saying my rantings are the truth? OK. Cool
It is true that engineers use findings from NIST, but doesn't mean their WTC7 investigation was complete or accurate.
Do you mean did anyone build a 94 story building and then drop a 12 story building on top of it?
