FLITCH BEAMS - STEEL ON OUTSIDE OF LUMBER

[PT999]

I am reviewing a situation where flitch beams are needed, but there are already (2) 2 x 12's in place.
Can steel plates be added to lumber forming a flitch plate with the lumber in the middle?

Under the correct conditions you can add steel plates to the outside of wood beams ending up with a flitch beam. You might want to take a look at this thread.

Buckling of the plate between the bolts will be more critical as it is not sandwiched between the timber beams, as is usually the case.

Can you add additional timber outside the steel plates? That would control buckling.
