Summary

 
This paper investigates stress-strain state of hull with longitudinal and transverse stiffeners under compression due to flexible lines (straps). Architecturally, two hull variants have been studied: rectangular with roundings at bilges and cylindrical. The problem was solved as per well-known analytical expressions, whereas stress-strain parameters of “hullstrap” system, depending on strap stiffness and presence of “loose” contact with the strap and the plating, were updated in ANSYS and LS-DYNA software packages. The study yielded the following data: stress-strain parameters of plating taking into account longitudinal and transverse stiffeners; loading patterns for separate hull elements (plate, stiffener) depending on strap stiffness; and loading patterns for separate hull elements in case of “loose” contact with straps in the areas of finite length.
