I agree that the W6x9 is too small to "detail" (not enough room for bolts, etc.)

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.
