Sam,
 
Could you be more specific about your question?  I ran the axial/moment curve using PCACol v3.0, turning all the phi factors to 1.0, and I got the curve similar to the curve shown on Example 7.8 at Notes on ACI 318-02.

Subject: Qustion to Robert Mast About PCA Notes Example 7.8 Biaxial Loading

Hi,
 
I don't know how to reach Mr. Robert F. Mast in regarding to questions about PCA Notes Example 7.8 Biaxial Loading.
 
In the example, with Pn = 1846 kips; Mnx = 461.5 & Mny=192.3 ft-kips
 
f'c = 5 ksi and fy=60 ksi.
 
24" square column with 4#11 bars.
 
I ran the loads by pcaColumn version 3.61.  It did not calculate at all!
 
I have to use a 26" square column with 12#11 bars to make it works.
 
PCA Notes is such a good and accurate reference,  which makes me think that I have done something wrong.
 
So if any of you can pass my question to Mr. Mast, I will sully appreciate.
 
Thanks
