I've always wondered why those were there

I always assumed it was to strengthen the flimsy metal #-o

They are, at least in some cases.

The fuel tanks themselves can be supported by their internal pressure, but the sections between tanks need a little extra help. Check out some decent cutaway diagrams of a Saturn V, for instance, and you will notice that in each stage the corrugated sections are those that do not form the extrnal section of a fuel tank.

On the history channel this weekend ("Save our History" I think) they had a show about the restoration of A-18. They were standing in one of the sections between the tanks to show the corrosion. The ribs were intact, but the skin behind it was pretty much gone. That tells me structure.
