I’m planning on using 3×8 (two 2x8s) built-up beams in the the construction of a deck.
My question: must the beams be constructed with spacers as a sandwich, then placed on top of the posts, or can I place one 2×8 on either side of the 4×4 post and through-bolt them to the post and each other with two bolts per post? This would leave a 3½” space between the 2x8s. Is this an acceptable design?
thanks.
