Weld Design - Corner Joint for Beam Hangers

[JoelTXCive]

I need to design some beam hangers for a 4x8 wood beam. The beam hanger will be welded to the side of a rectangular HSS section. (see attached example)

Our loading is about 1 kip per hanger from the attached wood beam.

The hanger will be constructed from 1/4" plate. Our hanger is is for a wood deck that is near salt water so everything will be galvanized and painted after fabrication.

I'm fine doing the all the fillet weld designs for the hangers, but i'm unsure of the best way to do the corner joints at the base of the hanger.

There seems to be too many options, and I cannot find good design examples. (I looked in the AISC design examples and AISC Design Guide 21 on Welding.)

With our light loading, I think a CJP would be overkill, but I'm not sure if I need a PJP butt welded corner joint; or maybe I can use Open corner joint of some sort with fillet welds? The open corner double fillet weld seems easy to design.

Any thoughts on which type I should select? Or suggestions where I can find some design examples?

Thank you.

For a 1 kip load I'd just use a single inside fillet weld on the inside closed corner or a single outside fillet on an open corner.
