AISC J3.6: 
The following is for calculating required unthreaded area of a bolt or threaded part
in a bearing connection.
This calculation can be used to calculate the required total unthreaded area, Ab, of a
bolt or bolts in a bearing connection subjected to a shear force. 



Bolt nominal shear stress (Fnv  ksi or MPa) 

Shear force on the bolt (Ru  kips or kN)
