Symbols

For symbols not defined in this section, refer to Ch 1, Sec 4.

P : Pressure applied on the considered superstructure side or deck, in kN/m2
  • P = PD for external decks,
  • P = Pdl for unexposed deck,
  • P = PSI for superstructure side.

PD : Lateral pressure for exposed decks, in kN/m2, as defined in Ch 4, Sec 5, [2] and in Ch 4, Sec 5, [4.2].

Pdl : Lateral pressure for unexposed decks, in kN/m2, as defined in Ch 4, Sec 6, [5].

PSI : Lateral pressure for superstructure side, in kN/m2, as defined in Ch 4, Sec 5, [4.3].

PFB : Lateral pressure for side shell plating, in kN/m2, affected by bow impact requirements according to Ch 4, Sec 5, [3.3.1].

PA : External pressure for end bulkheads of superstructure and deckhouse walls, in kN/m2 according to Ch 4, Sec 5, [4.4.1].

bdg : Effective bending span, in m, as defined in Ch 3, Sec 7.

shr : Effective shear span, in m, as defined in Ch 3, Sec 7.

c : Coefficient taken as:
  • c = 0.75 for beams, girders and transverses which are simply supported in one or both ends.
  • c = 0.55 in other cases.
