CJP Groove Weld Question

[kylesito]

I am analyzing an existing assembly. The situation is that I have two plates butting each other above the top flange of a beam with a complete joint penetration groove weld specified to splice the two plates together (9/32" gap between them).

My question, does the groove weld effectively bond all three elements (two plates plus top flange) or just the two plates? My objective is trying to determine whether this weld is sufficient in transfering horizontal shear from bending of the element into the top plates.

This may be fairly simple but, surprisngly enough, I have not encountered many situations in my career which call for CJP groove welds and this is not something I have considered before.

The transverse splice would not transfer enough load to take any credit for. Longitudinal (in the beam direction) welds would do that more effectively; flanged beams are often reinforced in this manner. Structural design codes have rules for the calculations.
