Some Misunderstandings Related to WTC Collapse Analysis

[Jeffrey Orling]

Very good explanation... much more logical than truther CD nonsense. I would point out that the columns virtually post initiation show that the "failed" or came apart... at their connection splices which were not aligned with the the floor system. The 36' length columns had connections at about 4' above the floor slab. The splce was simply to keep the two columns aligned and offered very little resistence to lateral motion. That was accomplished by the three floors and the bracing that supported them above the splice.

When the floors were stripped away in the collapse and floow of the floor mass down through the areas BETWEEN the columns which Albert refers to as a structure void (and is correct)...this left the columns with no lateral bracing and the strength of a column is determined in part by its unbraced length. So the floor stripping led to column weakening and then buckling and fracturing of the splices and the core columns came apart like pick up sticks. Not a single bit of evidence of explosives dismembering the frame.

But then again you'd have had to have studied the debris and the columns lying there to understand this... and know how the frame was erected... and how the bracing was attached and where... and so on and so on... or

You can listen to people who have no idea about any of the above but spout junk which sounds like science. And you believe it because it fits your need and preconcieved beliefs.
