Abstract
The buckling strength of irregular shaped members of offshore structures is evaluated by a design guide and numerical methods in this study. The buckling strength of members of offshore structures is calculated by using DNV-RP-C201 which is established for idealized plate structures. Because of irregularity of members, the buckling behavior calculated by the design guide is different from the real behavior. The result is compared with the buckling strength by classical finite element model using the commercial software ABAQUS in order to check the applicability of the guide. We carried out this studies with three different approaches: (1) the arc-length method, (2) the static stabilizing method with artificial damping for local instability. We also give a well-known buckling problem of circular cylindrical shell under axial compression.
