I-Shaped Members and Channels Shear Design per AISC 360-16 with ideCAD

How does ideCAD calculate I-shaped members and Channels' shear strength according to AISC 360-16?


  • The shear strength of I-shaped members and channels is calculated automatically according to AISC 360-16.


Symbols

Aw = area of web, dtw, in.2 (mm2)
Cv1 = Web shear 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)
tw = thickness of web, in. (mm)
λw = Limiting width-to-thickness parameter


The nominal shear strength, Vn, for I-shaped members and channels is calculated as shown below.

For webs of rolled I-shaped members with

The web shear strength coefficient, Cv, is calculated as shown below for all other I-shaped members and channels.

The web shear plate shear buckling coefficient, kv, is calculated as shown below for all other I-shaped members and channels.
