# 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?

• The shear strength of single angles and tees is calculated automatically according to AISC 360-16.

• The shear strength of rectangular HSS, box sections, and other singly and doubly symmetric members is calculated automatically according to AISC 360-16.

Symbols

Aw = Shear area
Ag = 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)
Cv2 = web shear buckling strength coefficient.
E = Modulus of elasticity of steel = 29,000 ksi (200 000 MPa)
Fy = 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)
Vn = Nominal shear strength, kips (N)
t = thickness of angle leg or tee stem, in. (mm)
λw = Limiting width-to-thickness parameter

The nominal shear strength, Vn, for single angles and tees is calculated as shown below.

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

and

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