Exterior Deck
(OP)
Got a few questions on how you guys handle deck lateral loads.
Client wants a deck fastened to the house with ledger board, then clear span out to end. About 16' span, and deck will be about 30' along the house. he wants to use a post support at the base, not embed into concrete. I am trying to decide what way to take lateral load, just all thru the ledger, which is what I think the loads will be.
Whats your thoughts on this scenario?
Thanks

How about the deck pulling away from the house?
I'd say look at DCA 6 Residential Deck Guide for help and as an intro. http://www.awc.org/codes-standards/publications/dc...

Alternatively, you can do knee braces at the posts. I'm not a fan of this, but it works per the code.

Have you ever tried to get the numbers to work out on a knee brace? The connections are tough.
Also, every kneebrace I see is lagged into the bottom of a double 2x10 beam with the 1/2"Ø fastener going between the plys of the beam. I wonder how you figure out that capacity?
