AASHTO Chapter 10 lists allowable bearing capacities in terms of psi or ksi for A307, A325 and A490 for bearing type shear.  Neither Chapter 10 nor Chapter 14 for bearings seems to indicate what is allowable for F1554 anchors.  Using the AISC method would allow 0.17Fu for shear stress on threaded rod.  Is there a section of AASHTO that allows for this same criteria?  Or is there some reference to this formula or F1554 anchors anywhere?  Even the AASHTO M 314-90 does not discuss allowable stress, only giving values for tensile strength.

I've dealt with this issue recently.  In my AISC 3rd edition (LRFD) Table J3.2 gives the Shear strength in bearing-type connections.  F1554 anchor rods have a nominal strength of 0.40Fu (Threaded) and 0.50Fu (Not Threaded).  I compared this to the ASD approach -0.17Fu Threaded and 0.22Fu Not Threaded- using service loads and the results were similar.
