If you look at the bottom image on page 8 you will see a cross section of a perimeter column with some decent detail.

A few things come to mind when looking at the image that are pertinent to the collapse theories that float around here.

1. The space between the aluminum facade and the box beam is filled with vermiculite. According to some sources there was 8 million pounds of vermiculite in the towers. Also, I think it is interesting that having a cavity filled with vermiculite in each perimeter box column explains all sorts of dust "phenomena" that CT'er like to make hay of.

2. Another thing of interest is the connection of the aluminum facade (note the use of the word facade) to the box beam. There seems to be only a small conact area, just enough to attached the facade to the beam. The point being that the facade was just that, a facade, and was not intented to provide structural support. Which flys in the face of the posted "article" (amazingly this happens all the time) pretense the the WTC was getting weaker everyday. So weak it needed to be demolished.
