None of this (in the link here) applies to toroidal space stations. The torus shape referred to in the link is maintained by its spin and its self-gravity. People live on the outside of it, and atmosphere is held in the same way that Earth holds atmosphere, by gravity.
A space station that rotates for artificial gravity is completely different. In fact, its gravity is so little that it doesn't matter for any of the structural engineering. It can be completely neglected. The difference in mass between the two proposals is huge, by a factor of like 10^12.
