Specific details of overall trans-verse strength calculations for ocean dry-cargo one-hold vessels
The advent of one-hold ocean dry-cargo vessels called for the analysis of their stress-strained state taking into account interactions with hatch covers. An approximate method of structural analysis under overall transverse bending of these vessels is justified. Results of the analysis for one of these vessels are in satisfactory agreement with benchmark results obtained by finite element method (FEM) both for plate representation (ISPA software) and rod representation (FEM-94 software). Summation of stresses is found to be required in the base section of deck stringer and web frame elements in mid-hold area, also it is required to control the highly stressed state of buttresses at hatch-side coamings and ensure local strength of hatch cover fixing details
