Abstract

Corrugated bulkheads are
widely used in ship and offshore structures giving higher load carrying
capacity compared to the flat plates. As a case study this paper attempts to investigate
the effect of rounded corners on corrugated bulkheads with respect to buckling
strength. Non-linear finite element analysis using ABAQUS is utilized. Rounded
and sharp comers are being compared for a typical geometry with three different
plate-thicknesses in order to find out if the rounded corners give additional
strength and therefore can be used to reduce the flange-width. It is shown that
the linear buckling load is larger for round cornered bulkheads. However, the
ultimate strength is smaller than for a similar bulkhead with sharp comers. The
results and insights derived from the present work are drawn.
