Hello all:
 
This is my time where I have had this situation.  I have a 2 story frame with 3 bays.  # bays are needed to keep p less than 1.25.  These are the beams from analysis:
 
The roof beams are .76-.78 of allowable
The floor beams are .60-.82 of allowable
The floor beams are .74-.84 of allowable
 
 20'                        28'                    6'
 
W12x40                W12x53            W12x16        Roof
 
 
W14x48                W14x61           W6x9          2nd Floor
 
All columns W18x60
 
 
I would usually think to use a W14x22 at the floor not a W6x9
 
I would like to here others thoughts.
