Not sure how to ask this question.
say a deck comes 10 feet off the back of the house and is 11 feet wide. its a second story deck with 2x8 joist. Along the back side (furthest from house) of the deck there are 3 metal poles offering the support. my question is this. How far can you you extend the deck with out adding more support if additional 2x8 joist were add on the outside starting from the house and running as one peice and bolted in?
