Look at page 6-57, section I 5.4. Strength of Channel Shear Connectors. I
can't find where channel shear connectors are precluded. I do see that they
aren't specifically listed in the reference in section 5.b. I don't know
why you couldn't use the same reduction factor as for studs in a formed
steel deck using the strength of the channel connectors.
