Abstract (eng): | The current thesis investigates a cruise ship structural concept which enables to use large interchangeable modules for interior outfitting. The structure has non-longitudinal-load carrying accommodation decks and a narrow deckhouse. The hull-deckhouse interaction and performance of the proposed structure under vertical bending is determined and compared to a conventional cruise ship structure which has internal longitudinal bulkheads for carrying the shear forces in the superstructure. The investigation is conducted by implementing Finite Element Method. The results indicate that the removal of the decks from the conventional cruise ship structure does not change the nature of the hull-deckhouse interaction. The responses of the compared structures were strongly affected by shear lag hull-deckhouse interaction induced secondary effects. It is also shown that the proposed structure can achieve the same stiffness under vertical bending as the conventional cruise ship structure while achieving smaller weight and the height of the vertical centre of gravity of the steel structure. The investigation assures that even at the early design phase, the Finite Element Method is the only reliable way to evaluate the response of the modern cruise ship structures. |
