I have a barn with load-bearing vertical wooden beams (the ones that support the building, not sure of the correct name). They have been resting on large stones which have now shifted or sunk, so some of the beams are suspended in the air. I'm thinking about casting new footings, but how should I attach the beams to the concrete without them rotting? Beam shoes are hardly an option, the beams are roughly 20x20 or round.
 
There is iron that you can cast down, one per side. Then it becomes like regular 100mm post shoes. If you then place paper between the beam and the shoe, you are doing as the experts usually suggest.
 
It should work fine, but doesn't the cardboard/rubber get flattened and torn apart by the pressure from above?
 
As long as it doesn't move and chafe, there is no problem with the pressure. It's more the age that later makes the sill paper quite fragile.

You can secure it with linseed oil and balsam turpentine which provides a little extra rot protection before the sill paper is mounted. You can also staple the paper with a staple gun, so you can cast in place afterwards.

Support your wall stud and preferably lift it 2-3cm with a jack. Staple the paper in place. Temporarily screw these post bases with small screws. Build a mold and cast the iron in place.

After a week or so, you can release the irons and lower the post onto the concrete and secure with proper screws.
