Ram Frame Cb factor

[CLT49er]

So I have been looking through the program menus and the manual and cannot seem to find a way to set Cb = 1.0 in RAM Frame Standard Steel Provisions for the AISC 360-10 Code. Does anyone know of a way to do this or does the program not allow a user to override the value for Cb? I know it can be done in the RAM Steel Beam Module. I am using version 14.07.01.01.

You are correct, the Ram Frame program always calculates Cb in steel beam (and column) design based on the forces in each unbraced segment. Are you just trying to be conservative here or is there some other critical reacon to use Cb=1?
