Qestion about porch/addition post to footer connection
Hi, I am in the process of starting to build a 16x18 addition to my home that will set on top of a raised platform/deck to be built. the deck will attach to the house and then extend out 16 feet. The deck will be 2x12 on 16"ctrs. The deck support will handled by two perpendicular beams. My question is...should the 6x6 posts that support these beams be set into the concrete footers or should I use the "Simpson" type of attachment connectors that are bolted to the footer when its poured and then they are nailed or bolted to the 6x6 post I believe???? Wouldn't setting the 6x6 directly into the concrete at the time of pour provide a more stable foundation?? My only concern about doing it this way was would the 6x6 then be susceptable to rot even if it is a treated piece? I do get some high winds at times where I live. Thanks for any input!

we use Simpson connectors in that application, they'll meet all local codes here in the midwest. Here's a link to the design we typically use.http://www.strongtie.com/products/co...s_list/AB.html
Hope that helps.

A 16' X 18' addition to the house that you will build on a deck? What are you going to use for a perimeter footing? (Good luck getting a permit to build this addition with one!!)

You forgot to mention that little detail in your original post. Sounded like you were planning a stick-built addition to the house to me.
You can do those on a deck (I am assuming that this is a sunroom or patio room similar to what you see in the photos on the website for www.c-thru.com).
But be aware, that all of the load of this room will be on the perimeter walls of the room -- THAT is where you need the beams of the deck to be. When I build these rooms on a deck, I use double joists under the side walls of the room, and a row of blocking between the joists directly under the outside wall of the room.
Why 6X6 for the posts? I would use 4X4's. They will match up to the beam (assuming that you are using a 4X6 for the beams). And, like Awesomedell said, use Simpson post bases under the posts (they make them for 6X6 posts too, if you are going to use them) rather than embed the wood in the concrete. And use a cap like a BC4 or BC6 at the top of the post to connect it to the beam.
