5.3.2 Symbols
The following symbols apply in this Section:

AL = shear area of longitudinal members
As = total area of stiffeners in width Sw, as shown in Figure 5.8 for orthotropic steel decks
AT = shear area of transverse members

B = bridge width

G = shear modulus

IL = longitudinal moment of inertia of a grillage member

IT = transverse moment of inertia of a grillage member

JG = torsional inertia of a beam
JL = longitudinal torsional inertia of a grillage member
JT = transverse torsional inertia of a grillage member

S = centre-to-centre spacing of longitudinal girders of a deck-on-girder bridge, m; centre-to-centre spacing of circular voids of a voided slab bridge, m; centre-to-centre spacing of spines of a multi-spine bridge, m

SL = width of a slab or deck associated to longitudinal members in grillage analysis

ST = width of a slab or a deck associated to transverse members in grillage analysis

t = overall thickness of a slab

ts = thickness of the slabs of rectangular voided-slab bridges

tv = depth of circular or rectangular void in voided slabs

tw = thickness of webs in rectangular voided slabs
t1 = slab thickness at the exterior edge of a tapered slab; thickness of the top slab of rectangular
voided-slab bridges
t2 = slab thickness of a tapered slab at the edge of the flange of the exterior girder; thickness of the
bottom slab of rectangular voided-slab bridges

Vy = maximum intensity of transverse vertical shear in shear-connected beam bridges in
Clause 5.7.4.1
W = the maximum axle load of the CL-625 Truck (175 kN)
