Please provide the quote or page from an engineer that says that photo shows what you say it shows.
Given the fact that you've screwed up so MANY photo interpretations, you can't be trusted as the only source to make said claim about that photo.
Who else agrees with you?
See chapter 2.1 for the passage where the structural engineer who is certified in 12 states identifies the concrete core.
Now explain where the "floor" fell from if you try to presnt it as such.
I don't see Domel's analysis of that photo in his paper saying that the photo contains a concrete wall like you say it does. Who backs your analysis of that photo other than yourself? As I have shown before and you've admitted, you make WAY too many mistakes when analyzing photos and what they supposedly show. WAY TOO MANY.
So who else analyzed that photo other than you and reached the same conclusion that it shows a concrete wall?
No other analysis of this photo other than your own eh Chris? That means it's bogus because YOU can't be trusted to make a correct assessment.
