So now I have two ways to look at the right side of the equation from my first post;
EQ2) Pn/1.67 ≥ 0.6DL + 0.6WL
1) ASCE 7 Commentary - No factor of safety added. 0.6 added to bring ASD in line with LRFD.
2) IBC - 0.6 factor added to ensure a only 2/3 DL used to resist overturning (they call...
Interestingly I see this note in the link that PhamEng just posted.
If we are limiting something to 2/3 it's actual value then, I would argue, this is a FOS.

Thanks for the feedback.
@Chris3eb - I had never read or heard what you highlighted regarding the 0.6D being similar to 0.6W in that the 0.6 was used to bring it in line with strength design. I'm not sure that it changes the argument for the increase to 0.6 if...
So, this has probably been talked to death over the years but I can't find a thread that discusses this question fully. Should an engineer combine material factor of safety's (Ω in AISI, AISC, etc) with Building Code environmental load factors (ASCE 7-16, Section 2.4 ASD)?
Say I'm designing a...
