Hi,
I am simply thinking of the factor ns in the calculation of resistance limit in AISC J.3.8 slip-critical bolt for high strength bolts.
As one of the factor for determining the value R, ns or number of slip planes (in some articles it is mentioned as equal to shear planes), is a significant factor considering in some connection where it has multiple connected members overlapping one another, for example, the value will of R be huge. Is there a limitation in which the value of the resulted R is limited?, due to the fact that slip resistance should not exceed tension resistance of the bolt itself.
I have attached a capture of my simple comparison for a single M20 bolt in relation with the question above. To picture the case, if we have ns=3 then the value of R from allowable slip failure will be bigger than allowable tension of bolt.
