The gravity column design interaction equation H1-1a in RAM SS does not account for the Mux/(0.9Mnx) in the unity equation. Why is that ?
Make sure you go to the next page of the report, it's actually Eq H1-2 that controls here.
If you reduce your report margins you can get it all on one sheet.
As a further test I set the minor axis eccentricity for column 3B at L12 to 19" and then the program reports H1-1a controls (and the column fails).
I still have to check into why the alternate condition of using Mrx/Mcx vs. Mry/Mcy is not reported here.
Thank you Seth yes I saw that earlier the column was controlled by Eqn H1-2 and it gave a DCR of 0.902. But that happened because Eqn H1-1a did not consider Mrx/Mcx (which comes to around 0.15) in the equation and if added to 0.819 (Pr/Pc) it would give a higher DCR. Please let me know if otherwise.
