Line load across an HSS tube

Does anyone have a handy solution for a load applied by a plate across an HSS section, where the buckling of the tube wall may likely occur. This would take account of the radiused corners.

The actual application is a 1" cap plate welded to a W column and the HSS beam is welded to this cap plate to develop a small moment. The moment force being treated as a line load across the HSS beam at the edge of the cap plate.

Thanks...

Oh just one wall loaded axially. If you have access to AISC Design Examples V14.1, There is an example (K.11) for Cont. Beam over HSS column that includes a local check of the HSS sidewalls for yielding and crippling. Same limit states as Table K1.2 from AISC 360-10

Coincidentally, the STI webinar, currently watching handles this exact type of problem. Thanks...
