Welded Stud in bending

[shacked]

So I came up with a connection for a stairway handrail post and now I am having difficulty with the calculations. See attached sketch.

My 1st thought would be to determine the baseplate thickness that is welded into the post, then determine the welded stud diameter in bending. This is where I am a little hesitant, since the only listed yield stress for bolts are for F1554 anchor bolts.

I realize that bolts for structural connections shouldn't be designed to resist bending, but I believe that this is a special case since the failure would not cause a catastrophic failure, especially if the bolt is over sized.

Also, what guidelines would I use for the allowable bending since everything associated with AISC 360 is related to shapes and not fasteners in bending?

What say you?

The bolt develops the tension from rail post bending equal to the distance from the centreline of the bolt to the edge of the post base. The post base has flexure equal to the force on the bolt to the face of the post.

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?

Aside from the heresy that is welding bolts, design the bolt for resisting the equivalent prying tensile load.

Take moment at end of channel. Determine bolt tensile force to resist moment. Design channel accordingly. Also consider edge distance of bolt from end of channel.
