Objectives A Roll-on/Roll-off(Ro-Ro)ship is a modern ship type with high technology and high added value. Due to the specification of its structure, a consensus on buckling and fatigue checking for Ro-Ro ships has not been reached among the different classification societies of the world.
Methods On the basis of analyzing the structural characteristics of Ro-Ro ships, the present study considers the direct calculation of buckling strength, advanced buckling analysis and fatigue analysis of a selected section of a large Ro-Ro ship. The calculations are conducted on the basis of self-developed software from the SJTU KSHIP Project. The pretreatment of buckling and fatigue assessment are established in accordance with the DNV standard "Strength Analysis of Hull Structure of Roll-on/Roll-off Ships and Car Carriers", and the related CCS rules.
Results The calculated buckling strength, advanced buckling strength and fatigue strength of the target cabin meet the requirements of the related rules.
Conclusions The contents of this paper have a certain reference value for the related structural analysis of Ro-Ro ships.
