ASTM A500? Does AISC or AISI control design?
ASTM A500? Does AISC or AISI control design?
(OP)
I am determining the allowable bending stress for a 1 1/2x1 1/2 tube using ASTM A500 Grade B steel. This is referenced in both AISC 9th Edition and AISI Cold Formed Steel Design Manual. For AISC the bending equation is typical, but for AISI there is an omega value to devide your allowable by. This greatly effects the allowable bending stress of the member. Any ideas which one should govern and why?

According to AISC 9th Edition Table 3 (Page 1-92) all A500 Grade B steel is cold formed. Initially this is why I thought that I would need to design according to AISI. But in AISC it provides load tables for structural tubing with A500 Grade B. So which should govern, AISC or AISI.
If calculating using AISI there is an omega factor that would reduce my nominal flexural strength by .6 (1/1.67) compared to the nominal flexural strenghth by AISC design.
This is just confusing to me which to use when it is referenced in both. Thanks for the help.

As an engineer that has just been introduced to this board and am posting for the first time, I would like to say thanks for everyone's responses and thanks for this board.
