built up beam shear flow- calc check
(OP)
I am making a composite wood beam out of a double 2x5 with a 2x4 flat on top. The beam is spanning 16 ft and is supporting 40 plf. Using shear flow to calc the fastened spacing for the flat 2x4 I am coming up with 50 lb/in! This seems very excessive to me. Anyone want to double check for me?

From there, you can make a nailing schedule (that the contractor will probably dismiss entirely)

Either way, wouldn't that shear flow be divided by two since you have two web members?
