Single Angles, Tees, Rectangular HSS, Box sections, and other Singly and Doubly Symmetric Members' Shear Design per AISC 360-16 with ideCAD

How does ideCAD calculate single angles, tees, rectangular HSS, box sections, and other singly and doubly symmetric members' shear strength according to AISC 360-16?

Symbols

A_w = Shear area
A_g = gross cross-sectional area of the member, in.² (mm²)
b = width of the leg resisting the shear force or depth of the tee stem, 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)
h = clear distance between flanges less the fillet at each flange, in. (mm)
V_n = Nominal shear strength, kips (N)
t = thickness of angle leg or tee stem, in. (mm)
λ_w = Limiting width-to-thickness parameter

The nominal shear strength, V_n, for single angles and tees 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.

and

The nominal shear strength, V_n, for round HSS is calculated as shown below.
