Moment connections between beams of different depths 1

[Ipetu]

A W8x18 beam and a W14x22 beam frame into the opposite sides of a W10x16 bream in a moment connection. The challenge in this type of configuration is that the W8 is 2" shallower than the W10 and the W14 is 4" deeper than the W10. Any ideas on making this work are appreciated.

For the W8x18 to W10x16 connection factored forces to be resisted are 33 ft-kips moment and 21 kips shear. For the W14x22 to W10x16 connection the factored forces to be resisted are 33 ft-kips moment and 31 kips shear.

I would definitely go with the bolted flange plates at beam tops. I don't necessarily feel comfortable with the connectegr's plates almost halfway through the W14.. But like the overall idea.

Maybe an angle bolted at the W10 bottom flange and welded to W14? what do you think connectegr?

shear plate - shear connection. fillet weld (at beams) and field bolt (at W10 flange) the angles. bolt the top moment plate. is that possible to erect that kind of configuration? eww...

I can't picture the orientation of the angle you mention. Field fillet welds of the flanges would require overhead welds.
