Ship structure deals with the supporting members which maintain hull strength, oppose hull deformation, and transfer stress in a ship. Typically, this refers to steel or aluminum construction, as opposed to wood or composites.
Classification society rules will provided minimum values for section modulus, area, thickness, etc. for various structural members through standard calculations. These often tedious calculations provide a relatively quick way to produce a ships scantlings, however as they are somewhat generic, the tendency is to produce an overbuilt (and thus over-heavy) ship. An alternative is to submit finite element analysis results.
