Bracing

[redhead2]

I am going to build a 27'x40' pole garage and was wondering about using 2x6's on the walls and laying them flat between the post. This way I won't have to have boards on inside and outside for metal and drywall. my question is if I go this way will I need to have diagonal braces and if so how would you place them?
Thanks for help

The diagonal bracing will be provided by the steel, you can install temporary bracing on the inside until the steel is up. It seems to me the biggest problem to overcome will be the 2x6's sagging. The sagging might be taken care of by running a 2x6 directly underneath or above your top and bottom boards, turning those into an "L" shape. The center ones would be held in place by the steel. You could use joist hangers on the end of the boards where they attach to the poles. It seems like a good idea, it will be interesting to see if anyone else has done this or has reasons to not do it.

We have the same problem when we erect metal buildings. We either place 2x4 spacers between the girts and remove them after sheeting or use strapping screwed to each girt and the eave girt. We probably use the strapping more often because there is material left over from the roof. We only use boards if there is enough dunnage on the job.

I did my pole barn like that. I believe it's called "Commercial Girts". I did not diagonal brace. I am slowly finishing inside with insulation and OSB so I will have support under each girt where the 4x8 sheets end. Outside is board and batten so some support there but not diagonal. The OSB should fill that task.
