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

ϕ_w : Angle, in deg, between the stiffener or primary supporting member web and the attached plating, see Figure 14. ϕ_w is to be taken equal to 90 deg if the angle is greater than or equal to 75 deg.

_bdg : Effective bending span, in m, as defined in [1.1.2] for stiffeners and [1.1.6] for primary supporting members.

_shr : Effective shear span, in m, as defined in [1.1.3] for stiffeners and [1.1.7] for primary supporting members.

: Full length of stiffener or of primary supporting member, in m, between their supports.

s : Stiffener spacing, in mm, as defined in [1.2].

S : Primary supporting member spacing, in m, as defined in [1.2].

a : Length, in mm, of EPP as defined in [2.1.1].

b : Breadth, in mm, of EPP as defined in [2.1.1].

h_stf : Stiffener height, including the face plate, in mm.

t_p : Net thickness of attached plate, in mm.

t_w : Net web thickness, in mm. For bulb profiles, see [1.4.1].

b_f : Breadth of flange, in mm, see Ch 3, Sec 2, Figure 2. For bulb profiles, see [1.4.1].

t_f : Net thickness of flange, in mm.

PSM : Primary Supporting Member.

EPP : Elementary Plate Panel.

LCP : Load Calculation Point.
