Weak-Axis Shear Design in Doubly Symmetric and Singly Symmetric Shapes per AISC 360-16 with ideCAD

How does ideCAD calculate the shear strength of weak axis in doubly symmetric and singly symmetric shapes according to AISC 360-16?

• The weak axis shear strength is calculated automatically according to AISC 360-16.

Symbols

A_g = gross cross-sectional area of the member, in.² (mm²)
b_f = width of flange, in. (mm)
C_v2 = web shear buckling strength coefficient.
E = Modulus of elasticity of steel = 29,000 ksi (200 000 MPa)
F_y = specified minimum yield stress of the type of steel being used, ksi (MPa)
V_n = Nominal shear strength, kips (N)
t_f = thickness of flange, in. (mm)

The nominal shear strength, V_n, for doubly and singly symmetric shapes loaded in the weak axis is calculated as shown below.

The nominal shear strength, V_n, for rectangular HSS, box sections, and other singly and doubly symmetric members is calculated as shown below.
