If it will be shop/storage and not tightly enclosed, the poles should work fine. Even though such toxic materials are discouraged here, recycling them from other uses is frugal.
If a 20' clear span is acceptable, you could do it with a row of posts down the center, and a ridgepole with rafter poles every few feet. The required size and spacing depend on your climate: how much snow do you get in the worst winters (average is irrelevant here)? What kind of extreme wind loads do you have? Any other factors like earthquakes to consider?
The sketch you posted is not sound, as the sloping rafters will push the walls apart with or without a ridgepole. You need a ridge post or a truss, and a 40' truss requires professional-grade engineering.

A couple things come to mind without really getting into the meat of the design...
I think you're right about clear span being unlikely, but it would certainly be helpful to know how much clear span you absolutely need?
Do you have a quality ventilator to use if you are cutting treated utility poles?
Do you have access to heavy equipment to move and lift these poles?
No, it'll be used as nothing more than storage/shop.Tyler Ludens wrote:Is this meant to be a dwelling? Utility poles outgas stinky toxic gick.
