Design of lifting lugs
MecaLug Pro offers the same features of the base version of the software of analyzing a single lug or trunnions, but MecaLug Pro has the added benefit of being able to apply those lugs to a lifting system and analyze what loads would be seen by the crane, cable, and lugs. Making it an all-in-one lifting design software.
Design of lifting lugs
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.
