CHS Moment Connection

[IH1980]

Easy one for somebody I reckon:

I have a chs which cantilevers out from a flat plate. It is fully welded to the plate with a fillet weld around its perimeter. How do I calculate the moment capacity of this connection? I have done 'what I think' is right, but it has now become the critical location which limits the load capacity so I need to check my method. I have a fixed weld size and the known weld transverse capacity.

In "Design of Weldments" by Blodgett, he has an example for a fillet weld about a round section to a flat plate. See 6.3-14 in the book. It takes a small amount of modification because the example has stiffeners, but you should get the gist of it.

Side note. If anyone is looking to pick up books by Blodgett, they are very reasonable through Lincoln Electric.
