You have been placed in moderation due to excessive off topic posts.Bentham, you seem to be so pre-occupied with saying everything is too complex to figure out, that you failed to realize that I said the severe deformation of the east wall exterior columns would have to occur in a natural scenario when the east interior comes down.
The NIST model shows this deformation because they are pretending it is natural and removing the east interior. In reality, the east interior is not gone and that is why we don't see the exterior deformation as shown in the NIST model. I am speaking of the buckling of the columns at the top in their model, which Mick didn't seem to think could happen as he thought the fact that it was a tube would make a difference. I explained to him that the tube was quite wide and the north and south walls would not have much of an effect on most of the columns of the east wall.
The lack of east exterior wall deformation high in the building in the real collapse is because the east side interior did not collapse the way NIST claims. That is a fairy tale and the structural behavior proves it. I haven't seen anyone who supports the NIST WTC 7 report conclusions have an answer for it.
I also want to complain about how long it takes for my posts to appear. The last one took about 12 hours. I can't deal with that and then respond quickly. This site was not like that before and this large wait time is a real drag on the discussion.
