Want to build large wood shed/ storage building

[skiwest]

My next  project now that the cabin ins almost done is to build a wood shed / storage building.  Still have a lot of fire wood to store from the original 2 acers that was cleared and tarps only last 2 years before they are in shreds.  Thinking of 12- to 14 feet deep by 36 feet long.  Three bays two for wood and one to park the skid steer.  Maybe after a couple of years one of the wood bays to be used for hay. 

Want to keep it simple so was thinking of a single slope roof, front to back, so snow would slide off back.    Would use a metal roof.  Also as we have a lot of lodge pole pine I wanted to use those for most of materail.  I have one of those chainsaw mills so was going to give that a try.

One question I had was should I use the wood that was cut 3-4 years ago and has been piled since then or cut down fresh?  Also was going to pour concrete piers and attach the posts to those.  That way wood would be out of the dirt as would rather not coat ends as somewhat close ot shallow well.

There seems to be a lot of that sort of structure in area but haven't found on on the net.

My firewood piles have usually gone uncovered except for pieces of scrap plywood or metal roofing used primarily to keep snow off it.  Rain on the pile is probably less of a problem to the drying and seasoning of the wood than it appears to be, unless you get lots of rain.  Any thoughts?  Keeping snow and ice off the wood is probably more important because it adds water directly to the stove when it melts in there.
My thinking is, if I have limited resources to build a pole barn or shelter, the firewood would be the last thing I would worry about getting covered from the rain.

Well have got a ton ot fire wood now that will probably rot it i don't get it covered.  do get a lot of snow in winter.  Once wood is mostly used up could use bay for hay.  So just one bay for wood long term.

What is your snow and/ or wind load?

This company has some woodshed/utility building designs that might work for you:  http://www.jamaicacottageshop.com/gallery.asp You'd have to scale them up for the size you're talking about building.

Snow load is 70lbs/ft2, wind speed 54mph per the building code

[skiwest]

something like this but each bay about this size and deeper, each bay 8 feet wide maybe 9 as i have a big skid steer and 10 feet deep , again big skid steer and want hay storage

I asked about the load to size the beam over the doorways.
Looks like the snow load will control with 70 psf live load+10 psf dead load so 80 psf total load
At the original size you were thinking about 12' wide x 14' deep. The front beam would support 1/2 the roof, the back wall would support the other half. So, 7'x12'x80psf=6720lbs that would be in the range of a 6x10 for decent wood. You've downsized in the last post so lets check that too, 5'x8'x80psf=3200lbs, more like a 3x8.

14' rafters on 2' centers, in the codebook its getting a little beyond 2x12's, they are fine at 16" centers.
10' rafter span on 2', 2x10's are plenty, at 16" 2x8's would work.

Looks like a typical "pole shed" should flip the bill.  Common design for wood storage and machinery.

Sorry about changing the dimensions , still a bit fluid in my mind.  Want to use as much as possible wood from property for posts and major beams.

The snow load number is the ground design number so I'm pretty sure you reduce it for both being elevated and depending on the roof slope.  Going to use metal roof so not going to be very conservative as the snow will usually slide.

For rafters was gong to use pine poles so surprized on the size of the rafters.  For the beans not too concerned as there is a large spruce that was blown over last year that I was planning to cut up for beams.
