RE: ACI 318 Appendix D

Section 8.5 of AISC 341-05 essentially negates the seismic provisions in ACI 318 Appendix D for anchor bolts at steel column base plates.  It is interesting that the "steel code" allows exceptions to the seismic provisions of the "concrete code"!?

Jules,
 
What is ACI 341-05? It appears to be a manual I don't have. Can you tell us what Section 8.5 says?
 
Thanks in Advance

Bill,
 
I've been reading through all the answers on this subject but nobody mentioned the exception on AISC 341-05 8.5. It solves most of the problems for anchoring column base plates, I use it.
Regards.

O.K., I've beaten my head against the wall long enough. I've decided that a post-installed anchor won't work in tension for anything I design.

 

I feel better now.
