RAM SS Seismic Stability Coefficient Calculation

Hi - 

I was hoping that someone would have some further information on how RAM Frame calculates the seismic stability coefficient (theta). When I do a quick hand check of the numbers given in the report, I find that the reported thetas are significantly larger than they should be. 

I've included a couple sheets for an example. If we choose to check Level 21 for loading the X direction, these are the numbers that I'm getting when Ie = 1.5 and Cd = 5.5.

theta = 9784 * 0.81 * 1.5 / 574 / ((244.82 - 226.82) * 12) / 5.5 = 0.017

RAM reported theta = 0.064

Thanks for the help,
