In reply to the discussion: 9/11 Physics: "You Can't Use Common Sense" [View all]AZCat
(8,345 posts)23. I don't think I agree with your assessment.
The assumption about the top piece and the bottom piece instantaneously impacting is in favor of collapse arrest, in my opinion, because it increases the bottom portion's ability to resist the force as that force is spread across the entire impact face. A non-simultaneous impact would result in force being applied to individual members in the bottom part in succession rather than concert, and therefore would increase the chances of failure and collapse continuation because it is much easier to overload a single structural member than it is to overload several.
