Threshold Value of Stiffener Bending Rigidity of Transverse Densely Stiffened Plate Under Pure Shear

Abstract

Abstract: Side shells of bulk carriers composed of transverse densely stiffened plate are subjected to large inplane shearing forces, however stiffener bending rigidity is designed not according to shearing force but according to lateral pressure based on IACS common structural rules for bulk carriers. So it is necessary to investigate the threshold value of stiffener bending rigidity for the stiffened plate under shearing loads. Pure shear buckling strength and ultimate strength of transverse densely stiffened plates with different stiffener bending rigidities were investigated. Then the two kinds of stiffener bending rigidity threshold values were identified respectively when the two kinds of strength of stiffened plate reach the material shear yield limit, which were compared with the calculating value based on AASHTO specifications. The result indicates that the stiffener bending rigidity should be decided by ultimate strength analysis.

Key words: transverse densely stiffened plate, pure shear, elastic buckling strength, ultimate strength, threshold value of dimensionless stiffener bending rigidity
