I have before; it's all on the right hand side of the Architects and Engineers for 9/11 truth page:

There are also some that make it unusual for a CD. However, these unusual characteristics can still be accounted for by simply setting up an unusual CD.
what is the nature of this unusual CD and how does it differ from a "normal" CD?
Normal CDs start at the bottom, as happened in the case of WTC 7. In the twin towers, however, it started in the plane crash zones. The alternative theory argument is that this was done in order to make it appear to the average citizen that the planes and the resulting fires brought down the building instead of the truth; that they were brought down by CD.
The characteristics for a CD that the WTC collapses displayed can be found here:
in cases like this a person must find their own evidence, not rely on someone elses "word for it".
I know of no serious debater here who refuses to quote certain authorities; whether it be from NIST or Ryan Mackey for the official story side or on Steven Jones, Architects and Engineers for 9/11 Truth, David Griffin, Jim Hoffman and others for the alternate story side. Now, can you find anything that you disagree with in their list? And if so, what and why do you disagree with it?
It also exhibited none of the characteristics of destruction by fire:
1. Slow onset with large visible deformations
2. Asymmetrical collapse which follows the path of least resistance (laws of conservation of momentum would cause a falling, to the side most damaged by the fires)
3. Evidence of fire temperatures capable of softening steel
Finally, high-rise buildings with much larger, hotter, and longer lasting fires have never “collapsed”.
i'm not sure about 1 but:
2. the videos taken on 9-11 does indeed show the tops of the towers leaning to one side right before the collapse.
Only one; and yes, you're right it was leaning, something that can certainly happen in CDs (in fact, it is very hard to have a building collapse straight down even in CDs); but you didn't get a huge section of the building crashing down to the ground because it was pulverized in mid air.
almost one entire side of one of the WTC towers was still standing after the collapse.
For what, a second or 2? If memory serves, demolitions at times are not completely successful; sometimes explosives have to be put in again (and this time the conditions are much more dangerous). I'm sure that a side of the framework standing for a second or 2 is well within tolerance levels for a very successful CD.
3. do you doubt that jet fuel temperatures are sufficient to soften steel?
Perhaps in a sustained burn. But Kevin Ryan sums it up quite well in my view:
****************************************
"This story just does not add up," Ryan wrote in his e-mail to Frank Gayle, deputy chief of the institute's metallurgy division, who is playing a prominent role in the agency investigation. "If steel from those buildings did soften or melt, I'm sure we can all agree that this was certainly not due to jet fuel fires of any kind, let alone the briefly burning fires in those towers."

finally, the buildings you mention were essentially girders with floors and walls attached.
the WTC buildings was of a different construction altogether.
Yes, the WTC buildings were of a stronger contruction.
watch and compare the videos, trust your eyes scott
One's eyes can tell us certain facts. But the brain has to interpret those facts and ascertain others from it. To do this, it frequently needs certain knowledge, knowledge that I would argue you may not yet have...
