Thanks for the tips and yes hokie66 that was my thought process as well. I know the top bolts in the end plate of the W10 are not doing anything with the moment transfer, but I thought they could even be used as erection bolts to get the W10 in place before the W4s are installed. Stiffener plate...
I'm trying to design a beam-thru-beam connection for a cantilevered canopy beam on the front of a building. I'm trying to frame a W4x13 (cantilever beam) and W10 into opposite sides of a W16x31 beam.
I've seen some similar connection detail approaches in a previous thread on here...
