Thank you, jmiec, I did not know that, as I started practice with 99 code.
WillisV, I do know some local codes have certain overrides (such as Chicago Building Code limits lintel deflections to L/600 or 0.3in, whichever is greater), but I couldn't find any in IBC 2003 (adopted code by the municipality with jurisdiction) regarding reinforcement in footings.
MYerges; yes, it is per foot of width and I reduced the section per 22.4.8. Moment of 4.1 kip-ft is the ultimate moment using 0.9 reduction factor for 4000 psi concrete, since tension in concrete governs. However, since I had room to play - I used 0.65 factor to obtain 3.4 kip-ft, because it could be argued that without reinforcement a brittle failure occurs, therefore requiring more reduction.
I think I will get an answer to this question, because I issued the drawings and calcs for city review. Final design was; plain concrete in footing (12" thick), but temperature and shrinkage reinf in foundation wall (13" thick). foundation bears @ 42" depth, so foundation wall is only 2.5 feet high. Thank you all for discussion, if i get comments from the city reviewer soon - I'll post them.
