AISC Section J10.8 - additional stiffener requirements

I have been reading through the limit states for transverse stiffeners. I am attempting to formulate a design strategy for stiffening column base plates to avoid using extremely thick plates when the moment gets large. I have come to the conclusion that, because the stiffener is welded to both the base plate and the column, the moment will transfer through the welds along the face of the column resulting in a force couple that acts on the extreme ends of the stiffener welded to the column. I am attempting to understand if because of this, that it would be necessary to check the column for the possible inclusion of transverse stiffeners to avoid the limit state failures in section J10 of the AISC spec. I am also attempting to interpret the additional requirements, particularly how to calculate the forces transferred through the welds attached to the flange and web of the column. I would appreciate any insight into this problem. Thanks!
