Method & assumptions
- Throat thickness te = 0.707·w (for equal-leg fillet).
- φRw per unit length = φ·Fnw·te; φ = 0.75; Fnw = 0.6·FEXX·(1.0 + 0.50·sin¹·⁵θ) (J2-5).
- Base metal shear rupture per length = φ·0.6·Fu·t; φ = 0.75. Controls if base metal is thinner than ~1.41·w (rule of thumb).
- Use lower of (weld) and (base metal) capacities.
- For full strength of base metal (Type J2): wmin based on AISC J2.2b plate thickness table (not handled here).
