I am designing a steel shed. I did manual calculations for the initial selection of sizes. But when I modeled it in ETABS all of them failed. For columns my initial section was W4x13 and it was failing in shear and D/C. I am attaching the file here.
The main issue is I don't know which checks should be applied in these members. And how should I control drift?
