af is flange area in this code, does it include compression and tension flange?
i can't find more commentary for it and the similar formula，af is compression flange area in aisc 89. so i want to make sure i didn't misunderstand.
thank you.
i am pretty sure this is the compression flange since this is about "compensation" of the thin web by a sufficiently thick flange.
forgot to add "...since this is about "compensation" of the thin web by a thick flange to avoid stability problems."
not familiar with s16, but on s06, just after the index there are definitions and notation sections. have you looked there?  
thank you gcjr.

s16 is steel design code. i had no idea for s06
sorry, the risks of typing too fast and not paying enough attention. obviously i meant s6, the bridge code
