I am planning on moving an existing structure and adding some shed roofs onto it for a barn/storage/workshop. The existing structure is an odd two story building that is sitting on concrete piers and will be sitting on concrete piers when it is moved. That is because the property is in a zone A 100 year flood plain. I have never built any substantial structure and have a few questions about the additional shed roofs and support.
Here is a picture of what it will generally look like but not nearly so nice. And the lean to sheds will probably be enclosed instead of open. The area underneath this structure will be covered with crushed rock (gravel) not concrete.
Since the existing structure will be on concrete piers that happen to be going 15 feet into the ground due to the poor soil on this property I was talking to the foundation contractor about having him drill the holes for the supports. These supports will be 8 inch diameter gun barrel pilings that can be pressure treated to 0.60 pcf and then coated with a polymer coating.
In my experience any pole barn construction that I was around simply buried the poles into the ground, sometimes concreted sometimes not. Depending on the site conditions those poles would rot out in some amount of time. Some people constructed their pole barns just sitting on concrete piers. But with the pressure treatment and polymer coating on the underground portion that should extend the life of these columns probably past my expiration date of life.
Now for the questions:
Is it better to sink the poles into the ground so they can take shear load or is it okay to just have them attached to concrete piers (that will be seven feet deep due to soil conditions)?
How would you attach the poles to the concrete? Simpson has a PBV (Post Base for Vigas) that look acceptable for this type of structure since the tops of the poles will all be attached together by the top rails and also the girts.
Any other suggestions on how to construct this structure?
Sorry for the long post.
