Re: Need "Flitch-plate" design example

I have done this many times.
Points to heed
1)    If plate is not within the timber plies, i.e. laterally restrained, you have to calculate the bolt spaces by investigating the potential for plate buckling.
2    If the plate is laterally supported such as with the bottom/top flange like with an angle then with good bolting patterns the section properties can be calculated with tranformed sections methods.

Otherwise no different from ordinary beam design.  I have used this for many instances where header depth is restricted and a full steel section is not wanted.  Works like a hot damn!
