attaching beam to post for 2 story deck

We have to build a two story deck 22′ wide 14′ deep. Actually the lower level will be quite a bit wider but that’s immaterial. The main level will heve an intermediate beam. My question is for the second level. We’ll have14′ long 2×12 joists 12″ oc. Planning on triple 2×12 for a beam. As this will also support a roof I’d like to use 3 6×6 posts. Beam span is about 10′ . What is the best bet for the beam/post junction. Would a notch of 1-1/2 inces be suficient. I would carriage bolt at the post/beam joints (2 bolts ) as well as along the beam . I dont trust lags anywhere on a deck. Thanks Mike

a notch an inch and a half sufficient? No.
either for get the notch set the beam on top with a siimpson tie, or use just two 2x's and a 3'' notch.

If notch each side of the 6x6 1.5", then use some 4x4's ripped down for intermediate blocking, you would have the strongest joint, IMHO.
I think Sphere was reading that you would only make one notch, so the other beam would be relying on the carriage bolts only. This would not be nearly as strong.

Why use a built up beam?
For far less money you can go to your local sawmill and have a beam made from one piece of wood. Then you could do a mortice and tenion joint that would look elegant and be far less costly a Kluggy looking bracket/lag bolt/toe nail..
very good point..I tend to lean that way too..just didn't think of it ...too much roof and sun.

Priced at my sawmill a 14 foot long 12 inches deep and 6 inches wide nice decay resistant white oak beam would cost you $67.20
You could do it in the weaker Eastern White pine for $33.60, but I prefer the oak..
what's the price of three 2x12's 14 feet long? Think the typical nailed together doug/ fir or western white woods is as strong or looks as nice?
