Gypsum is a covering only. It does not bear loads at all.
Gypsum Construction Handbook
its drywall basically. Gypsum was the wall covering on the inside and in some areas most likely on the outside walls of the elevator shafts and or stairwell walls. I have gypsum nearly the same specs in my office. They do not bear loads. The loads are carried by the frame work and inner wall supports.
In the case of the WTC towers, they were a inner wall covering as well. Whether it was in an elevator shaft or an office wall, they served the same purpose. The steel underneath and behind those gypsum coverings were what carried the load.
I never said they carried loads. The gypsum planking was placed between the concrete slabs of the floors and between cross members using channels that they fit into on the top and bottom, just like you see in this photo:

That is gypsum planking BETWEEN the horizontal channels. They also used the gypsum planking to surround the columns in addition to sometimes using fireproofing.
LOL, well then what the hell are you arguing with me about?
I think we got a wrong idea about what one another was saying somewhere along the line...
For my end I am sorry if something I said gave you the wrong impression. I was just responding to your post to me. My bad, I just assumed from your response you were implying the gypsum made the shafts....

Nah. I was just making a comment on the fact that from what I have seen, there was no concrete other than the floors in the towers and that the shafts and walls were comprised of gypsum planks placed between the concrete floors and horizontal steel members.
No worries.
