SILVA-CAMPILLO, Arturo; SUAREZ-BERMEJO, Juan Carlos  and  HERREROS-SIERRA, Miguel Ángel. Evaluation and structural analysis of the torsion box of a 2400 TEU container ship. Ingeniería Mecánica [online]. 2022, vol.25, n.3, pp. 64-71.  Epub Dec 20, 2022. ISSN 1815-5944.

The aim of this study was to evaluate by means of numerical analysis the structure of the torsion box of a 2400 TEU feeder container ship, from the establishment of the fatigue limit state and the ultimate limit state along its perimeter. By using the fatigue limit state and different geometrical alternatives, relative to the local dimensions of the torsion box, the degree of influence of these is obtained in the determination of the fatigue life relative to nine possible arrangements of the structural detail, made up of the intersection of the longitudinal reinforcement and the bulwarks. In terms of the ultimate limit state, the influence of the geometrical modifications on the establishment of the values referring to the local buckling stresses, the shear stresses induced by the vertical and horizontal shear forces and the tangential warping stresses is determined.

Keywords : torsion box; container ship; structural strength; shear stress.
