how to design wood beam with steel side plates?
(OP)
I am trying to strengthen an existing 12" deep wood beam by adding 5.5" deep x 0.25" thick steel side plates. The steel plates can only be placed along the bottom of the beam. The steel plates are being added because the support system of the wood beam is being altered, so now the beam can no longer handle the bending and shear stress applied to it. The beam will be supported with new steel tube columns. I have never design a wood beam with steel side plates before. Can anyone point me to a good reference with design guidelines? I already have NDS design manual.

You would need to determine the fasteners required to transfer the interface shear.
For what it's worth, I'm not a huge fan of this. Why can't you reinforce the sides like normal?, or provide column capitals to retain the current support lengths.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
