14x20 skid shed build

No. Post and beam gains it's strength from the posts being locked into the earth. This gives is a significant amount of strength that is lost when the studs of the wall are sitting on top of a foundation.

I think you're confusing pole construction with post and beam.

I have four post and beam buildings that were built in the 1850's. All of them sit on stone foundations. Two of them have basements, one of them is just on stones at grade, one was originally on granite piers, since replaced with masonry. None of them have wood going into the ground. The bents are braced diagonally with 4x4's into the sills and connecting beams. The sheathing is inch pine boards placed horizontally, I don't think it contributes much shear strength.

These buildings have stood for 160 years. From my big barn I can see the ocean, and these buildings withstood three hurricanes in the 20th century, including a direct hit from a category 3 in 1938. (1938 New England hurricane - Wikipedia). We regularly get winds over 60 MPH in the winter and snow. Local building code is that roofs have to handle a 30 pound/sf snow load and wind of 129 mph.

Sorry, you're correct. I thought I read something different. You are also correct on the diagonal bracing.

Normal construction needs poles or a foundation for stability and/or strength. The Sampson brackets we used at the joints add great strength to the structure since this is a "skid shed". I'll post a few photos of the shed we skidded off this site to build this one. It stayed true after being moved 300ft.

Hello,
I think your job looks great, but I have the same question as one of the other viewers, why didn't you just use normal construction techniques. Like putting the floor down, then a sole plate, studs and a double top plate. If you were worried about strength and racking when moving it, you could have put some let-in diagonal bracing in each wall. The only reason I say this is because I know how expensive those metal braces are, plus all the bolts........that was a lot of money for all those angles and bolts ! Just my 2 cents.......it does look good and will probably last many years !!!!!

I have seen kit sheds built like this, with bottom, sides and ceiling truss built as one piece.

I have a 12x16 shed I built 20 yrs ago I want to put 16' runners under so I can move it. Floor joists are 12ft 4x4s every 2ft, set on blocks. On a slight slope front to back. Gonna be a pain to put runners under now..

I used to use those "one piece" building frames made at a truss works. We can no longer get them and this shed was likely to wide or tall for them anyway. So obliviously we built the same thing on site using these Simpson brackets.

If anyone wants to purchase plans for this shed, PM me. This building is engineered and built to our locale codes. The roof is 100lb PSF. Its actually my design but we had to have PE sign off on them, in order for us to get a permit. The engineer also said it needs to be staked down or a 60mph side wind will roll it.

I was going to ask about staking it down.

What is the advantage over standard stick construction. Savings in labor materials? Improved function? Having an engineer to approve shed plans there must be a good reason.

 

[ArlyA]

The only advantage is there is no foundation and you can readily move it, if needed. (this design you can anyway) In our case, its located over a sewer line and we could not build a standard building with a foundation. This shed was large enough to be above the max you can have a "normal" skid shed which are not usually approved by a PE. This one was a waaaaays over the max.

Attached is a few recent photos. In the second one you can clearly see three horizontal 2x4's we added between the studs which I kind of thought someone might ask what they are for in earlier photos... These do two jobs. One is to protect people grabbing tools off the walls from the protruding and very sharp tin screws. The other is to give those screws much more materiel to hang onto should this shed be moved. Theses short 2x4's are tow screwed on through the stubs and the OSB is also attached to it before the tin it.

Hope you enjoy them.
