Exception: Continuity plates less than or equal to 3/8 in. (10 mm) shall be permitted to be welded to column flanges using double-sided fillet welds. The required strength of the fillet welds shall not be less than $F_{y} A_{c}$, where $A_{c}$ is defined as the contact areas between the continuity plate and the column flanges that have attached beam flanges and $F_{y}$ is defined as the specified minimum yield stress of the continuity plate.
