Unity Equation for Bolts in Shear and Tension in AISC 14th edition steel manual

[ENGINEER92]

Whenever I check bolts for tension and shear I use the following unity equation:

(V/ΦRn,v)+(T/ΦRn,t)<1.0

I have recently seen other engineers use the following equation:

(V/ΦRn,v)^2+(T/ΦRn,t)^2<1.0

Currently I am using the AISC 14th edition steel manual. I have looked through the steel manual and I am unable to find a unity equation for bolts. Does anyone know the where I can find the unity equation for bolts in the steel manual?

It was right in front of me, I found it at section J3.7.

If you have not already seen it, the Commentary to Section J3.7 provides an alternate formulation for the sloped portion of the Specification interaction equation; see Eq. (CJ-J3-6a) and Eq. (CJ-J3-6b). The results are identical to Specification Eq. (J3-3a) and Eq. (J3-3b) but they look a fair bit different.

Thank you Hokie for pointing out the commentary. It was very useful and explains the equations well.
