Note: Whitmore effective width uses 30-degree dispersion angle per AISC. Also check gusset plate for compression buckling (use Whitmore width with KL/r from average of 3 fold lines).

Reference

AISC Steel Construction Manual - Gusset Plate Design Whitmore section width: Lw = 2*L*tan(30) + member width Uniform Force Method: distributes brace force to beam and column Fillet weld: phi*Rn = 0.75*0.6*FEXX*0.707*w per inch Gusset checks: Whitmore yielding, buckling, block shear
