Implementing the rotational restraint effects of surrounding support members into plate buckling strength design
Plate buckling is a primary criterion for plated-structural design. In current structural design practice, the edges of plate elements are assumed to be simply supported. In reality, however, the plate edges are supported by longitudinal stiffeners and transverse frames, and thus there are some degrees of rotational restraints along the plate edges that are neither zero nor infinite but rather dependent on the torsional rigidity of the support members. The objective of this paper is to develop a method for implementing the rotational restraint effects into the plate buckling strength design. It aims to minimise the structural weight while maximising the plate buckling strength. In this paper, the buckling strength of plate elements subjected to compressive loads is calculated using design formulations. Examples are shown for the buckling strength design of steel plates in a Very Large Crude Carrier class tanker and a naval ship, demonstrating that the structural weight can be reduced by implementing the rotational restraint effects while meeting the plate buckling strength requirements associated with the structural safety design criteria.
