This thread isn't looking for what initiated collapse, or what transfer trusses and core columns were doing.@Joe Hill Presumable the structural failures could be initiated by destroying key components and initiating a run away progressive failure. So for example the support for TT1 if disabled...
We are asking if there's any way controlled demolition caused the east part of the perimeter frame to fall over at it's onset.
We know the perimeter frame was standing in a visibly static position, then lurched over at the instant the west penthouse initiated it's descent. Does that look like controlled demolition? How could controlled demolition make the structure move like that?
