In RAM SS, Beam gravity module. I am analyzing some web openings in the beam. The beam is designed as a composite beam. But the opening paramter, po, is checked against 5.6 ( recommended for steel section per AISC Design Guide #2)? Do you know the reason for that? Shouldn't it be compared to 6.0 ( recommended for composite section per AISC Design Guide #2) ? Please find the attached PDF and last page for the failure reason of web opening. Please let me know. Thanks!
