I need to span a beam 11' between two 6x6 posts to support the rafters for a covered pergola. I was thinking of fastening 3 pieces of 2x6 together to create a stronger piece. Is it possible?
Is there a calculator somewhere for this? I was looking at some tables, but most of them are for decks, which require higher loads than this - 10psf dead load, 5psf live load.
