That might happen at the east end but not the rest of the building where the core started down a split second before the exterior columns. You are grasping at straws.
In the NIST model, the exterior columns were intact until the core started pulling them down, then they buckled. i.e. no FFA.
Hogwash. The core could not make the resistance of the exterior columns go to zero instantly. As the engineering forum told Chris, the resistance reduction would be small at first.
I have read all the double talk.
The exterior columns are buckling in the NIST model and providing resistance as Sunder said. The NIST model does not fall at FFA. You refuse to deal with this fact.
Have you come to grips yet with the difference between "average" and "instantaneous" as it applies to acceleration, Chris?
