To build a pole barn question

[brushtrooper]

I have intentions to build a pole barn with roof and 3 sides enclosed. Now I have no experience in doing this. It will not be built on level grade either, more of a sloped terrain. I will be using 2-7/8" and 2-3/8" pipe for the structure. I will be the welder and I want to do this project start to finish.
Are there any good books out there that can help with planning the structure/pole placement etc?
My goal is 4 each 12' wide bays x 30' deep. I already have a crushed asphalt base laid down. This will be built in the middle of a ranch and no one can see it unless you are on the property.

I'm no builder, but can show you pics of something similar that will eventually be a pole barn with 3 enclosed sides. I can't remember the exact dimensions but it's close to what you have in mind:

Before:



During:







After:










There is a certain point where the supports begin to sag a little from the weight of the roof due to the length of the beams. If you look at the one side photo you can see the braces they welded up to take out the sag.

A few weeks later they finished the peaked roof awning with extension over the cabin and parking area.

Sometimes TBH blows my mind. I am planning to build one too and was about to post up the same general question.

You would be better to have two, 24' bays instead of four,12' bays. It would take six columns of 2 7/8" pipe, four, 30'x10" receiver channels and twelve 25'x10" purlins for the roof. For the walls you would need four 25'x8" purlins and four 30'x10" purlins.

You would need to weld two of the recievers together to make your center rafter and weld it on top of your center posts. Weld the other recievers to the top of your other poles. Then put your purlins inside the recievers and screw together. I like to go back later and weld. It should be very easy to do. You can get recievers and the purlins and tin from Metal Mart.

Here is the one I built at my house. It's 24'x40' 2 7/8 drill stem and purlin. I love it and have since lined ther perimeter with railroad ties and laid down two loads of rock. It really keeps the sun off my camper, and soon I will be adding shade netting to go on the south and west sides.

Good info...

I used this book; it is for wood structures but the principle is the same and should translate to metal easily.

A lot of places stock 20' perlin so you might want to change it a little to utilize them. I build a 20 x 40 and I used 2 7/8 for the post and 2 3/8 for my rafters. I used all 6" perlin. I only did a sloped roof because i plan on adding on another 20 x 40 later.

I built this by myself with the help of a kobato with a front end loader. I'm pretty sure i have less than $2k in it.

let me see if i can get the pics to load
