Built-up channel section - AISC 2010 - Qs and Qa factors.
(OP)
I'm designing a built-up channel section according to AISC 2010.
The section has slender web and flanges. I'm calculating the Qs and Qa factor according to the E7 Section.
My question is: Which section do I have to use to calculate the Qs factor? E7.1.(a) or E7.1.(b)
If the answer is E7.1.(b) should I use Table B4.1a (case 2) to determine the flanges slenderness?
Thanks in advance
