I am in the process of designing my deck and could use some advice. Here are some sketchup images for reference .The deck is 14'x14' with an additional 5'x5' bump out at the front for the stairs (see images). I plan on using composite decking for the top. Here are the framing details: ItemDetailsLedgers2x10Main Beam(3) 2x10Main Beam Span10' 10.5" (Max 11' 11")Main Beam Cantilever16" (Max 16")Small Beam(2) 2x10Small Beam Span4' 2.5"Small Beam Cantilever0"Joists2x10 (14' and 19' lengths)Max Joist Span12' 5.75" (Max 13'8")Joist Spacing12" OCJoist Cantilever15.25" (Max 16")*Note: I am in Edmonton, AB, Canada. Max measurements are from the Edmonton building code. Questions:I'm pretty sure everything here is to code but the more I read, the more I worry about the deck bouncing due to the large joist span. Should I redesign this to include two main beams (7' and 14' from the house)? This would allow me to use 2x8 joists instead of 2x10s.There is a smaller 8' ledger on the one side of the house (see images). Should I do anything special with it here given that there is a single joist running parallel to it? (I was simply planning on nailing that joist into the ledger for a little extra stability).I plan on installing a piece of blocking below the rim joist to extend the attachment surface for the stair stringers. This blocking piece will be attached to the rim joist via some pieces of 2x6 from the back side (see images). Is this OK?I have designed this to use some 19' joists. If I can't find lumber this long is it ok to screw two shorter pieces together (say with 3-4' overlap over the main beam)? If not, how should I build this? I want to build a strong and sturdy deck that will last a very long time. I am open to any critiques / advice you may have. I have not purchased any of the materials yet and am very flexible to design changes at this point. Thanks! via /r/DIY http://ift.tt/2w3v9dL
