Both the 2009 IRC and the DCA6-09 allow #2 southern pine 2x10s to span 13 feet 1 inch at 24 inches on-center at a design load of 50 psf. That means these joists can span the 12-foot depth of the deck, and the beam can be located at the perimeter. Nine joists will be needed for the 16-foot width.
I would connect with 2x12's to support your deck joists. 3. Deck could span 10' lengthwise with 2x6's on 2' centers (5 will do a 8' width with the first and last attached to the outside of the 6x6 pier posts and the remaining 3 at 2' increments in the midst). 2x8 joists would be better for a few more $$$. will be using pressure treated pilings spaced 7&#39; in width apart tied together with a 2x6 on each side. At 90 degree angles I will run five more 2x6&#39;s on 2&#39; centers to support the walkway. Will the 2x6 running lenmgthwise support an open span of 10&#39;...
