Designing a Combination Section
Designing a Combination Section
(OP)
I am designing a S12x40.8 beam that needs a C10x20 placed on top to form a combination section. I would like to show a stitch weld to attach the two sections together. How do I calculate the size and length of the weld to assure the combination section will act as a single beam? I have looked in several books and can not find any answer

I guess this is a motor driven trolley, in such case, I will use bolted connection rather than weld.

And, yes, VQ/Ib is your equation of choice to find the shear flow. You will not find any tables in AISC publications for this type of connection, although you will find combination section tables. The 9th edition has your specific combination on page 1-83, but you have to calculate the interstitial shear for the connection and design it yourself.
