Abstract

The main portion of ship’s structure is usually composed of stiffened plates. Under various loads applied to a ship, such as those due to cargo, buoyancy and waves, these stiffened plates are subjected to combined in plane and lateral loads. Longitudinal stiffeners attached to the plates may significantly increase the overall buckling loads of the resultant stiffened structures. In this work, eigen-buckling responses for a series of rectangular perfectly flat plates and longitudinally stiffened plates subjected to in plane axial forces for different depth of stiffeners are derived by finite element approach using general purpose software (ANSYS). Finally stiffener arrangements are explained in explicit form based on the results of numerical investigations of the non-linear behaviour of plates and stiffened plates.
