awww come on truthseeker..... did you never have a mecanno set as a kid?
These buildings are constructed...they are put together using relatively small pieces, in fact very small pieces relative to the overall structure.
As you know, the columns are not one continous piece of steel stretching from the ground to the roof...they are many lengths of steel bolted and welded together. But those joints, as you know, can also be the weakest part of the fabrication and so, when the column as a whole is stressed, those joints are the things that will snap.
The concrete was only 4 inches thick. As you know, that is so thin that it couldn't even support it's own weight and had to be supported on a metal deck which itself was supported on the floor trusses.
Imagine what happens to that thin concrete if you take away 50% of the floor trusses.........BANG! concrete snaps
The beauty of the wtc tower construction was it's way of creating maximum office space by avoiding the conventional steel frame design with all those pesky columns getting in the way of the MD's desk, and, as you know, instead it was constructed like a tube...or a tube within a tube.
As you know, conventional steel frame structures distribute the supported loads over the frame throughout the building. This can be quite neat because, as you know, the frame members can be spaced quite a distance apart and we can have big areas of glass or other funky cladding materials on the external face of the building. But, as you know, the wtc towers had this tube of closely spaced columns around the perimeter, which reduced the ability to have massive glass areas. But, as you know, this wasn't a problem because the height of the building was going to make large glass areas rather unnerving to some of the occupants.
But then, you knew all that already.
