Thank you! that's the article I was looking for:

Contractors building the Superdome also found that it required efforts and techniques that were a bit out of the ordinary, especially in the construction of its roof. For this building, the largest clear span steel structure in the world (as attested to by the new Guinness Book of World Records) is literally held together by its roof. In its flying - saucer-shaped design , the walls of the Superdome literally hang (for want of more descriptive term) from the roof, with the force vectors at foundation level pointing away from the center.

Roof, structurally, is not the same as roof cover. My understanding is that a small portion of the cover has come off, but have not heard that the roof supporting structure has been damaged.

Disclaimer: I am not an engineer.

Thanks for the correction. But keep in mind that the parts that are "failing" are essentially "sprayed on", and are not themselves structural in any way.
