Corrugated Bulkhead - Section Modulus
Section modulus of a unit corrugation in a vertical corrugated cargo-hold bulkhead - the primary scantling check per CSR-BC Part 1.
Corrugation depth
606.2mm
Section modulus per corrugation
6,807.2cm³
Formula, assumptions, and limits
Double-sided. Add shedder plates at base for tanker/chemical cargoes. Shear-area check separate (web thickness vs transverse shear).
