# Weak-Axis Shear Design in Doubly Symmetric and Singly Symmetric Shapes per AISC 360-16 with ideCAD

**How does ideCAD calculate the shear strength of weak axis in doubly symmetric and singly symmetric shapes according to AISC 360-16?**

The weak axis shear strength is calculated automatically according to

**AISC 360-16**.

**Symbols**

**A _{g}**

**=**gross cross-sectional area of the member, in.

^{2}(mm

^{2})

**b**_{f}**=**width of flange, in. (mm)

**C**_{v2}**=**web shear buckling strength coefficient.

**E****=**Modulus of elasticity of steel = 29,000 ksi (200 000 MPa)

**F**_{y}**=**specified minimum yield stress of the type of steel being used, ksi (MPa)

*= Nominal shear strength, kips (N)*

**V**_{n }*= thickness of flange, in. (mm)*

**t**_{f}The nominal shear strength, *V _{n}*, for doubly and singly symmetric shapes loaded in the weak axis is calculated as shown below.

The nominal shear strength, *V _{n}*, for rectangular HSS, box sections, and other singly and doubly symmetric members is calculated as shown below.
