I am rebuilding a porch on our 200+ year old house. It is in a historic section so I am limited to what materials I can use. The porch is 16' wide by 7' deep. I will have 3 wood posts across the front, and 2 half posts at house side. The full posts are 4.25" square, with a hollow center. Their load limit is 6000 lbs. I am hoping to find a 4x6x16 beam to span the front, but making the connection at the corner posts is where I have a concern. The old design was a half lap, where both beams were in shear. I would like to avoid that. And since I am trying to make this close to what it was, I am also wondering how to attach the beams to the posts. I don't want to see any hangers, or stongties visible.
