I'm curious as to how others design lifting lugs. I am using AISC D.5 and J.7. The lug I am designing appears to be governed by bearing strength using AISC Eq J7-1 Rn = 1.8FyApb. But I also found reference to ASME-BTH-1-2008 Eq 3-54 where the bearing capacity is P=0.63Fy(Dpin)t which is a big difference, 1.8Fy vs 0.63Fy. I don't have the actual ASME document.
Also a co-worker attended an AISC seminar on Practical Connection Designby Larry Muir and it was mentioned that AISC D.5 should not be used for lifting lugs.
