Connection structures between longitudinals and floor structures (i.e. slot structure) are one of the most fundamental structural elements in ships. The authors have developed a new type slot (APPLE SLOT) for the above connection structure, and already reported non-linear behaviors of the floor structure with the new type slot under a pure compressive load. In this paper, the authors have investigated the elasto-plastic large deflection behavior of the floor structure with the slots under "combined" loads, using non-linear FEM analyses and large structural model experiments. As results, characteristics of the behavior of the structure are revealed and the accuacy of non-linear FEM analysis under "combined" loads is verified.
