Pole Barn??

[GOODER30]

Pole Barn Design
I am designing a 24' X 30' pole style garage. I am thinking of using built-up 2x's mechanically fastened for my columns. Does anyone know how long should the splices be. And can someone tell me or point me in the right direction for for designing for diaphram action in pole barns. I have been searching for ever for an example of structural calculations for pole barns. I have found a couple of examples, but I see these pole barns being built and referncing the calculations I have found it seems the way people build them seems like they should fall right down, now granted the cals that I have are not the cals fors the pole barns I see going up. There seems to be some factors that make my cals unrealistic. If anyone could advise that would be great.

Try your local ag extension office. ISZ

The strength is in the outside sheathing. Yes, they are built very flimsy.

hey gooder30,

i have seen an old engineering design of pole bldgs on slideruleera's website. you can check it out and see if it helps. if so give him a star. if you cross-posted this you probably already got this info.

Check with the Midwest Planning Service:

Look under their Construction Section. Try the Post-Frame Building Handbook publication:

Try reading a book by Jack Sobon:
"Timber Frame Construction: All About Post and Beam Building".

The book details a traditional mortise & tenon style of construction, but it does have tons of good information from a structural standpoint. It is very descritive on the joinery. While you most likely will use newer mechanical joinery, it is very helpful in learning about the stresses and ways to build for strength. It also walks you through the construction of a simple shed.

I do not have a structural background and found this very helpful in planning my project which I hope to build next year.

Also, look at a product called Socket Systems -

They have some nice joinery systems for pole barns.
