I am doing a nominal moment strength calculation of the following SMF RC beam attached. I just wanted to ensure my approach was correct. The beam has two sets of 5 PT tendons on the compression side of the beam and the same amount on the tension side. Additionally, it has both compression rebar and tension rebar.
Compression:
Cc = 0.85f'cba
C's = e's *Es * A's
e's = (c-d')0.003/ c
C'ps = e'ps * Eps * A'ps
e'ps = (c-d'ps)0.003/ c
Tension:
T= As*fy
Tps = Aps*Fps
Iterating for c until T=C
