Design of Steel Members for Shear per AISC 360-16 §G
How does ideCAD calculate steel members' shear strength according to AISC 360-16?
The shear strength of steel elements is calculated automatically according to AISC 360-16.
Symbols
E = Modulus of elasticity of steel = 29,000 ksi (200 000 MPa)
Fy = Specified minimum yield stress
h = clear distance between flanges less the fillet at each flange, in. (mm)
Vn = Nominal shear strength, kips (N)
tw = thickness of web, in. (mm)
λw = Limiting width-to-thickness parameter
In design per share, it is assumed that shear force is completely carried by the web, no interaction between bending and shear occurs, yield stress in shear is,

The design shear strength =
The allowable shear strength =
The nominal shear strength, Vn, shall be determined depending on the slenderness defined by (h/tw) according to the limit state of shear yielding and shear buckling.
If
satisfies shear-yielding controls.
If
satisfies, shear buckling controls.
