Which was the point of my post, second response to the OP, where I stated:I don't see how any of this invalidates the main thrust of the NIST findings. It appears that there was small movements that NIST did not include but, how does this actually show they "got it wrong"? As far as I can tell all of these smaller movements seem to be related to the larger events that NIST used to shape their findings.
Maybe M Tom or femr2 could help clarify how all of this is important. If it's just to add to the knowledge base that's cool, if you think it's a "gotcha", I think you need to dig much deeper.
Whether it was "perimeter led" or "core led" does not change the overall picture that a weakened impact zone dropped the top block and from that point "global collapse was inevitable"....
4) The load redistribution events build up into a cascading sequence which weakens the impact and damage zone.
5) The damage reaches the point where there is insufficient remaining strength to support the "top block".
6) The impact zone ceases to support the Top Block.
However the concern that many members have, looking ahead a few steps, is that a "core led collapse" could make it easier to claim that the core was cut by demolition devices.
The practice that both Major_Tom and femr2 adopt in their posting, that of insisting on step by step exposing of their logic and not foreshadowing what is down the path, lends further support to those who see the path inevitably leading to claims of demolition.
I have commented previously on the discussion tactics and the inevitability that any attempt to sneak in a CD scenario will run into major barriers.
So let the "progressive revelation" tactics continue.
I also subscribe to "I don't see how any of this invalidates the main thrust of the NIST findings."
