Cribbing and their weight limits. I know that the standard 4x4 cribbing will hold approx 6000 lb per cross, standard lay of 2 each tier, will hold 24000 lb and with 3 tiers its 54k, but for some reason i cant remember the approx limit of the 6x6 and the 8x8. I was hoping someone could remind me of the limits for the larger sizes. Feb 10, 2014 The proof of this requires some relatively advanced mathematics, which you can find on many web sites, Google pendulum forces for more information. So in your case, if this is the only load, you need to design for the weight of the beam (static load).
I'm doing some preliminary research for a backyard project. I want to build a raised, one room wooden shack, approx 11.5'x16' (185 sq feet). For support, I'd like to use as few columns as possible. I was wondering if 4 6x6 wooden posts would be adequate. They need to bear the weight of the structure (wooden floors, walls, roof), a small wood stove, bed, table/chairs, sundries, and up to maybe 10 occupants (for small gatherings). So, perhaps 6000-7000 pounds total. What is the safe/conservative weight limit I can put on 6x6 posts?

Also, if 6x6 is not adequate, what size post would I need to go up to in order to support the weight?

tldr: how much weight can i put on a vertical 6x6 wood post?
Edit: Thanks for all of the advice. Sorry for the poorly worded question. I'm obviously a layman. I think I should mention at this point that I'm merely in the concept phase, and I will be working with a general contractor (family friend) and an architecture grad on the final plan. I joke, but I would never jeopardize my loved ones' safety--I might be an idiot, but I'm not an idiot. I just wanted to get a general idea of what I'm getting myself into, as I'll be doing all of the heavy lifting/digging and footing the bill.
Technical addendum: the structure will be built on a hill, with posts on one side extending approx 1.5 feet above ground, and about 4 feet above on the other. All will be set in concrete several feet below (I plan on inquiring what depth is recommended). I'd envisioned cantilevering 2-3 feet on all sides (again, I'm sure my vocabulary reveals my naivete), although after reading your responses I imagine I'll propose a 6 post plan, at least. I plan on cross bracing all posts, or as recommended by my resident experts.
