Eccentric load perpendicular to faying surface of weld group

[cepe01]

I am stumped on this eccentric load on weld group. Say you have a flat bar welded to a table and the bar cantilevers out like a diving board. This is a weld group in bending correct? If so can I use fb = Pe c/I ? (similar as laid out in this guide

http://www.bgstructuralengineering.com/BGSCM13/BGSCM005/BGSCM00502.htm)

If so how do I calculate the moment of inertia of a square or rectangular shaped weld?

I find plenty of examples of force acting in plane with the weld group or with eccentricity normal to faying surface but do not find any with eccentric force acting perpendicular to faying surface.

the steel manual provides the general formulas for moment of inertia of a line weld combining the results for each line of the box by the parallel axis theorem will give you the weld group moment of inertia.
