Help for steel stress check design
(OP)
Hallo, sorry for my english, I write from Italy.
I would like to know: when I perform the check of the structure (i.e. a simple steel beam) I obtain a Total Ratio of 0,997 (= 0,000 + 0,997 + 0,000)
My bending moment is Mu33= -70,697Kip*in and (I do like this in Italy) if SMayor= 2,087 and Fy=50, I thing that Resisting Bending Moment Mrd = 2,087*50= 104,35Kip*in
So that Mu33/Mrd = 70,697/104,35= 0,677 Mmayor ratio
Why sap2000 give me Mmayor ratio= 0,997 ???
thanks very much for help

Mu33/Mrd = 70,697/104,35=0,677*0,9(phi)=0,610 Mmayor ratio
but is always far away from 0,997 !
