Good day,
I am currently facing some doubts when it comes to designing a lug subject to an out of plane load.
Though lugs should be designed to be in line with the applied load, this is not always the case since fabrication and installation tolerances play a significant role.
It is also widely recommended by diverse design codes to consider a 5% side load acting on the inner part of the Shackle’s bow.
My specific concern relates to the check of the hole bearing capacity.
Following AISC’s Specification for Structural Steel Buildings, Chapter J7, it is possible to get formula to check the bearing capacity of the hole.
But this formula seems to be independent from the angle of the resultant load.
Hence my question is:
Are the formulae provided in Chapter J7 applicable for a case of a lug subject to an offset out of plane load (and consequent bending moment)?
If not, which shall be the considerations made?
Thanks in advance for any help on this subject.
