A NOTE ON THE APPLICATION OF MULTIPLE INPUT SPECTRUM THEORY TO COMBINE WAVE INDUCED STRESSES

The wave induced stresses in the ship structure are not solely dependent on a single type of loading. The most common example is the longitudinal stress at the deck edge due to bending. Because there is normally structural symmetry about the centerplane of the ship, quasi-static bending loads are most conveniently resolved into vertical and horizontal bending. The superposition of component stresses to yield a combined total stress is as basic and ordinary an approach in structural mechanics as it is in hydro-mechanics and rigid body dynamics. There are two complicating factors in the superposition of wave induced component stresses. The first is that the component loads which produce the component stresses are functions of time. The second factor is that the ultimate origin of wave induced loads (the waves themselves) must be considered to be random. Within the framework of the general assumptions which are ordinarily made about wave induced loads and elastic structural behavior, it is possible (to a point) to organize the problem of combined wave induced stresses into forms which are not unreasonable for application. This is the purpose of the present note.
