Some Misunderstandings Related to WTC Collapse Analysis

[Jeffrey Orling]

\

Just so others know, I explained this in detail to Jeffrey in an e-mail exchange a couple of years ago when he sent me his cartoons. He apparently doesn't understand or doesn't want to change what he has and is still trying to sell.

No Tony you simply said I was wrong and it was a several months ago less than a year. Do I have to post the email. Stop lying and who cares what the "others" think... I know what you said and I don't want to stop to that level. Go find another engineer aside from your partner to say that the hat trusses couldn't transfer loads to the facade from the core.

Jeffrey,

There is no way an entire 36 foot length could fail at one time with beams framing into the columns at every story. There was very little damage to the 97th floor core columns also and little to the core overall in WTC 1.

The failure was not over three stories it was at the 98th floor and went across the building on that floor in a 250 millisecond time frame. In my opinion, it would be nothing short of magic if this was a natural event.

The hat truss was not capable of transferring the core loads to the perimeter as it was not three stories deep over to the perimeter, as I thought you were saying earlier, which it would have to be to transfer those kinds of loads. The outriggers were simply A-frames beyond the core.

I can certainly prove that the A-frame outriggers could not have transferred a 12 story core gravity load to the perimeter columns.
