NOMENCLATURE FOR MEMBER PROPERTIES AND DIMENSIONS:

A = Cross-sectional area of member (in.^2)

d = Overall depth of member, parallel to X-axis (in.)

tw = Thickness of web of member (in.)

bf= Width of flange of member (in.)

tf= Thickness of flange of member (in.)T = Distance between fillets for wide-flange or channel shape (in.) = d-2*k

k = Distance from outer face of flange to web toe of fillet (in.)

k1 = Distance from web centerline to flange toe of fillet (in.)

gage = Standard gage (bolt spacing) for member (in.)

rt = Radius of gyration of compression flange plus 1/3 of compression web area, taken about an axis in plane of web (in.)

d/Af= Ratio of of total depth of member to area of compression flange of member = d/(bf*tf)

Ix = Moment of inertia of member taken about X-axis (in.^4)

Sx = Elastic section modulus of member taken about X-axis (in.^3)

rx = Radius of gyration of member taken about X-axis (in.) = SQRT(Ix/A)

Iy = Moment of inertia of member taken about Y-axis (in.^4)

Sy = Elastic section modulus of member taken about Y-axis (in.^3)

ry = Radius of gyration of member taken about Y-axis (in.) = SQRT(Iy/A)

Zx = Plastic section modulus of member taken about X-axis (in.^3)

Zy = Plastic section modulus of member taken about Y-axis (in.^3)

J = Torsional constant of member (in.^4)

Cw = Warping constant (in.^6)

a = Torsional property, a = SQRT(E*Cw/G*J)

E = Modulus of elasticity of steel = 29,000 ksi

G = Shear modulus of elasticity of steel = 11,200 ksi

Wno = Normalized warping function at a point at the flange edge (in.^2)

Sw = Warping statical moment at a point on the cross section (in.^4)Qf= Statical moment for a point in the flange directly above the vertical edge of the web (in.^3)

Qw = Statical moment at the mid-depth of the section (in.^3)

x(bar) = Distance from outside face of web of channel shape to Y-axis (in.)

eo = Horizontal distance from the outer edge of a channel web to its shear center (in.) = (approx.) t f*(d-tf)^2*(bf-tw/2)^2/(4*Ix)-tw/2
