Hello,
Per attached screen shot, W16x26 has a flange width of 5.5", and bolt gauge should be 2 3/4", but it is entered in Advance as 3 1/2".
Please fix this to be per AISC:
16.5" and over-7 1/2" ga
8-16 1/4...........5 1/2" ga
6-7 3/4"............3 1/2" ga
5-5 3/4"............2 3/4"
under 5"...........4" ga
Regards,
Ilko Dimitrov
