    Ive spent a lot of time researching and have designed a Hammerbeam barn frame.  Everything will be rough cut timbers.  Posts will be pressure treated and set at least 2 ft deep in concrete.  The bays will be 15 ft.  Starting out with 4 bays (5 trusses).  Building in North Georgia, very little snow.  I will have an engineer size the timbers and what species of wood to use.  Overall height is just under 27 ft.  9 pitch.  26ga tuff rib metal roof.  I would just like to know if there is anything major that ive missed before i get engineers involved.  The barn will be completely open more like a pavilion.  Engineer can decide spacing on rafters between bents.  I added the double posts under the trusses to help absorb the outward thrust and hopefully i will never have to add any more reinforcement.  I also plan to reinforce every joint possible with steel.  I think my design got rid of as many tension joints as possible.  Thanks in advance for any input!  Hopefully my drawing uploads!20190820_104346_compress84

    Your design looks great, the sheds roofs can/will take some of the outward thrust for you.  I would not recommend that you bury the post in the ground, even though they are PT.  They will rot over time (25-30 years) and your frame would easily outlast them.  It is time for you to call an engineer.  Good luck with your project and let us know how it goes.
