Allowable Bolt Stress for A307

[strainstress]

ASME gives allowable stress for A307 bolt as 7000 psi. However, AISC 9th edition, will allowable bolt stress of A307 as 20,000 psi. If the bolts I am trying to size are anchor bolts, do I still need to take allowable stress from ASME, or will AISC allowable stress be acceptable.


Thanks

That depends on the governing code and the customer's requirements. You could use ultimate strength if you want to...wouldn't be responsible, but you could use it with a healthy safety factor. (I don't think anyone actually would. It's just an illustration.)

If there is no verbage, then I would go by AISC Code and design for earthquake and wind loading if applicable using the AISC allowable stress in one of the accepted AISC analytical methods.
