Note: Standard shear tab (single plate) per AISC. Weld must be sized for eccentricity to bolt line. Ductility limit of w <= 5/8*tp ensures plate yields before weld fractures.

Reference

AISC Steel Construction Manual 15th Ed. - Single Plate Connections Two-sided fillet welds to column flange/web Direct shear: fv = Vu / (2*Lp) Eccentric moment: M = Vu * a (a = distance to bolt line) Combined: f_max = sqrt(fv^2 + fb^2) Ductility check: w <= 5/8*tp per AISC convention
