Bolts or nails...
(OP)
I am designing a pole barn type structure and have 6x6 posts @ 8' o.c. Between each post are two 2x12's which support the trusses. The owner would like to have the post sandwiched between the 2x12's and I am trying to figure out the best way to attached the 2x12's to the posts. My load on the 2x12's is 805 lb/ft. I was planning on calling for three 3/4" bolts to support the end of each 2x12 but is there some kind of nail I could use? Thanks.

As EOR's we should take the responsibility to design our structures to support the components we allow in our design per that industry standards.

As long as you are sharing the load equally between the 2x12's, the loads you give are service level, and you are ready to go with nails, the schedule in the image, where the red circles are the nails joining one of the beams to the post, and the blue ones those that join the other beam to the post, is enough. In each side beam, separation is 1 inch horizontally and 2 inches vertically.

Anyway I concurr with msquared that positive support be better, and woodman more or less in the same intent. This is just if you prefer nail ways. Even the bolts might ultimately be more reliable than the nails to disengagement or lack of serviceability.

Timber splits and often makes bolted connections unworkable.

As an aside, make sure you do a lateral analysis on your posts. A 6x6 lam post is more like a 4x5.25 post and will have problems in bending for higher wind loads and building heights exceeding 10ft.
