Assuming you only have one frame in the direction of loading and torsional
effects minimal to zero, it seems correct.

I'm resending this memo, because I have not heardanything.
The 1997 UBC Section 1630.1.1 has a "p" Reliability/redundancy Factor.
In equation (30-3) they have a "r" which for moment frames is " shall be
taken as the maximum of the sum of the shears in any two adjacent columns
in a moment frame bay divided by the story shear."
My question is in reviewing a pre-engineered single story building
with equally spaced moment frames consisting of 1 bay of 2 columns frames,
is the shear per column one half of the story shear, thereby "r" is equal
to (1/2 V+1/2V)/V =1.
Any input on this subject is greatly appreciated.
