In S-frame design code check results, I get 25kNm weak axis moment capacity for W150x22 (W6x15) section whereas it should be 13.8kNm as per code CSA - S16:19. Anyone insights?
Hello there, we'd be happy to dig in a bit deeper for you. Would you mind sending your model file, and the observations to our technical support team so we can provide further insights?

Hi Merlin,
Just closing the loop on this for anyone who may have followed this request. We reviewed your model, and found that it was deemed class 4 I-shaped member undergoing weak axis bending. Currently, S-STEEL uses the provisions in (F6-3) of the AISC 360-16 to calculate this moment capacity for CSA S16, due to a lack of clarify from CSA S16 codes at the time. We'll look into improving this with the Canadian approach in a future release.
