    Default Joist Bearing Question

    In the American Forest & Paper Association's Prescriptive Residential Wood
    Deck Construction Guide, which they claim is based on the 2009 International Residential Code, they list 3 acceptable methods for providing bearing to joists used on exterior decks.


    Two methods have the joist bearing directly on top of the beam and the third is metal joist hangers. The first pic below is from their Guide. I cannot find anything
    that specific in the IRC.


    In general I am wondering where the section they are using to support their opinion is. Specifically, I am wondering what the current concensus is on the use of wood ledger strips to provide bearing for joists on exterior decks. See the second pic below. Sorry the pic is poor quality because the deck is located on the side of a mountain and I was standing about 30 feet below in heavy fog while taking the picture.

    Thanks for the reply...is there anywhere that distinguishes any differences in what's allowed between interior and exterior (as in exposed to the weather)floor systems?

    R502.2.2-R502.2.2.4 deals specifically with decks, but it does not get anywhere detailed as the AF&PA deck guide. The AF&PA is referenced by the IRC & is considered as applicable.
