Does anyone know where I can get information on designing a flitch plate beam ?
I'm building a nearly flat patio roof off of the side of my garage. One end of the 2x6 rafters will be sitting on the top plate of the garage wall ( the soffit has been cut back to allow for this ), and the other end will sit on a beam supported by posts 14 Ft away. Since a 2x6 rafter 24" OC can't span this distance I want to see if a double 2x6 with a 3/16" or 1/4" flitch plate will do the job. I would like to find a "cookbook" type solution so I don't have to relearn all of the college math I have forgotten. My understanding is that the bolt pattern\schedule is important so I would need this info too.
I do ornamental ironwork and was thinking that the flitch plate could actually be a decorative element if allowed to protrude beyond the 2x6 at the end of the roof. For the overhang I could weld in a much wider plate and torch cut a nice design.
