Note: Directional strength increase per AISC J2.4b allows higher capacity for transverse welds (theta=90 deg gives 1.5x increase). Two-sided weld assumed for length calculation.

Reference

AISC 360 Chapter J2: Fillet weld strength: phi*Rn = 0.75 * 0.6 * FEXX * 0.707 * w Directional strength increase: (1.0 + 0.50 * sin^1.5(theta)) Min weld size: Table J2.4 (based on thicker part joined) Max weld size: thinner part thickness - 1/16" (if t >= 1/4")
