The hull internal structure is made up of several elements. There are three main types:
1. vertical longitudinal members (keel longitudinals)
2. horizontal longitudinal members (stringers, breasthooks, and you might include decks)
3. transverse members (frames, beams, floors)
It is hard to keep track of things because one type of member can be composed of subcomponents and members can flow into a different type of member.
A frame can include floors (the part under the deck) and beams but beams and floors do not have to be part of a frame.
Stringers flow into breasthooks and torpedo bulkheads. So part of a torpedo bulkhead could be called a stringer.
Furthermore, the members are not solid structures. Support structures flow and intersect in three dimension so many members have to be intercostal. The general rule is that vertical longitudinal members take precedence over transverse members that take place of horizontal longitudinal members.
Unlike a model ship, the hull shell was built first and the structural members were erected behind the shell. The shell was largely, if not entirely, self supporting.
Here is an image showing the underlying structure going by what the plans call things. The frames are in red. Note that the framing stops at the third deck within the citadel. There are webs at some frame locations that effectively extend the frames up to the second or main deck. Some of these have beams that go all the way across creating a full height frame. However, many of the frames do not have extensions above the third deck in this area. Apparently, the designers were relying on the stiffness and strength of the side armor for support here.
