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.
