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)
F_y = Specified minimum yield stress
h = clear distance between flanges less the fillet at each flange, in. (mm)
V_n = Nominal shear strength, kips (N)
t_w = thickness of web, in. (mm)
λ_w = 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, V_n, shall be determined depending on the slenderness defined by (h/t_w) according to the limit state of shear yielding and shear buckling.

• If satisfies shear-yielding controls.

• If satisfies, shear buckling controls.
