Looked in a couple of deck books and did not find an answer so here goes…
We just erected an arbor using rough hewn 6×6 locust posts as supports.
There are six of them, each in 3′ holes with 160-lbs of quickcrete.
We would like to hang a low deck on the structure.
There are two 10′ spans and two 8′ spans for attaching the beams.
The books show span charts for beams that are laid on their edge on top of the posts.
We will attach the beams on both sides of the face of the posts in order to double them up.
1. What size 2x board do we need in order to span 8′ and 10′ ?
(They will support 2×6 joists spaced 16″).
2. Could a single board on just one side of the post handle the load ?
Thanks for your help,
Alan
