Once again I'm in a predicament. I'm building a multilevel deck and the lower deck is going to require me to tie the joist directly into the beam. That is because I will not have enough ground clearance to do it the other way. In most of the diagrams I have seen, the beam is one continuous run and there are no problems. With my deck, I have to tie that lower deck beam into the 6'x 6" post of the upper deck. Will that 6"x 6" post give me the proper support, if I just use a hanger to mount the beam to it? The beam is 2-2"x8". I thought about notching the post but I have already notched it for the upper deck. I was concerned about the stability of that post with 2 notched out areas. The distance between the upper notche and the lower notch would be about 1 foot. I did not want to sandwich the beams around the post because that will only make the beam 2"x8" instead of the suggested 4" x 8". Hope that is kind of clear. Thank you.

Hello again....Here is something I just noticed about the above mentioned problem. I have about 4.5" of ground clearance on the post for the lower deck. Could I just use a 2" x 4" for the beam? At least that way, the joists will rest on top of the beam rather than attached to the face of the beam. Thank you.

Give me some details on size, post spacing, joist spans.
There are a number of ways to do this.
In this case, usually OK to notch a post in more than one location provided the notch is no more than half way thru and the notches create a tight fit or..... you can balloon frame by bolting the beam onto the face of the post and you take it one step further with a 1 x ribbon board notched into the post below the beam.
You could also sister a board onto the side of the post to support the beam.
This beam can also be a flush beam which has a number of advantages or a standard support beam with the header joist resting on the beam.

Multilevel deck....a 10'x 10' on top of a 16'deep x 18'wide deck .....6 -6"x 6" post...the first set of posts are 7' from ledger board....second set of post 6' from first set....I'm using 2"x 8" joist on top of 2" x 8" beams(at least for the the second set of posts) I need to connect a beam from c to b...But if I do a joist on top of beam scenario, i'll have to dig down....If I do a "connect joist to beam", I'll have to sandwich the post or maybe notch. Thanks again.

Can I start with a few questions. Then we can work from there.
How far is the top deck projecting over the lower deck?
How high is the top deck above the lower deck?
What is the span of the joists on the lower deck? that is from it's ledger to the beam.
What is the span of the posts? especially the lower deck.

there are a number of ways for a post to support a beam. You can notch all or part of the beam into the post, let it rest on top, bolt it thru an d also in some cases split the beam on each side of the post. notching the post in more than one place is ok as the beam acts as a squash block maintaining the strength of the post.
