Some Misunderstandings Related to WTC Collapse Analysis

[Jeffrey Orling]

The measurements show the North Tower continued to accelerate and gain velocity.

It is not apples and oranges to compare the Balzac-Vitry building to the North Tower in the sense that if a solid item hits another solid item in an impact, and causes it to accelerate, the impacting object has to decelerate (slow down). Isaac Newton showed us this a while back. In reality, the North Tower should have decelerated even more before any natural failure would occur because it was a stronger structure.

This works for me. It's a powerful argument.

The WTC towers were not a stronger structures... what collapsed over 10 - 14 seconds was the FLOORS which were likely weaker than a typical office floor system. No columns were crushed and they could have been twice as strong with the same floors and the collapse time would have been the same... it was a runaway floor collapse and had nothing to do with the columns.
