USUAL GAGES FOR ANGLES (inches) Leg 9 8 7 6 5 4 3-1/2 3 2-1/2 2 1-3/4 1-1/2 1-3/8 1-1/4 1 g 5 4-1/2 4 3-1/2 3 2-1/2 2 1-3/4 1-3/8 1-1/8 1 7/8 7/8 3/4 5/8 g1 3 3 2-1/2 2-1/4 2 g2 3 3 3 2-1/2 1-3/4 For an angle, the gage "g" shown is the distance from the back of the member to the bolt in the angle leg, when only one row of bolts is present. For angle legs >= 5", the potential for two rows of bolts exists. Thus, the gage "g1" is analogous to "g" for the other angle leg, and gage "g2" is the spacing between the first and second row of bolts. (See illustration and table in AISC 9th Ed. ASD Manual page 1-52.)

Q21

The wall thickness, 't', is the actual value, not the nominal wall thickness.

B24

The 'T' distance shown is the nominal "detailing" value, and not the "design" value. T = d(nom)-2*k(det).

B25

The 'k' distance shown is the "design" value, and not the nominal "detailing" value.

E26

For a channel, the "gage" shown is the distance from the back (web) of the member to the bolt in the flange.

B27

The "gage" shown is the spacing between the bolts in the flange. The "halve-gage" is taken each side of the member centerline. When a gage is displayed as a set of three numbers such as: (3) 5-1/2 (3) it refers to 4 rows of bolts with 3 "gages" or spacings = 3", 5-1/2", and 3" in this case.

N29

The radius of gyration for the minor (Y) axis, 'ry', with a 0" gap between back-to-back of angle legs.

N30

The radius of gyration for the minor (Y) axis, 'ry', with a 3/8" gap between back-to-back of angle legs.

N31

The radius of gyration for the minor (Y) axis, 'ry', with a 3/4" gap between back-to-back of angle legs.

H34

Torsional property, 'a', is determined as follows: a = SQRT(E*Cw/G*J) where: E = 29,000 ksi (Elastic Modulus) G = 11,200 ksi (Shear Modulus)

N45

Cross-sectional area, 'A', is determined as follows: A = b*t

N46

X-axis moment of inertia, 'Ix', is determined as follows: Ix = b*t^3/12

Q46

The wall thickness, 't', is the actual value, not the nominal wall thickness.

N47

X-axis section modulus, 'Sx', is determined as follows: Sx = b*t^2/6

N48

X-axis radius of gyration, 'rx', is determined as follows: rx = t/SQRT(12)

N49

Y-axis moment of inertia, 'Iy', is determined as follows: Iy = t*b^3/12

N50

Y-axis section modulus, 'Sy', is determined as follows: Sy = t*b^2/6

N51

Y-axis radius of gyration, 'ry', is determined as follows: ry = b/SQRT(12)

N52

Torsional constant, 'J', is determined as follows: J = b*t/12*(b^2+t^2)
