Mike, Please dont get me wrong. Your shop is beautiful and the workmanship is top drawer. Certainly one of the nicest builds ever showcased here.
I'm just echoing what my engineer explained to me when I was designing mine. After he explained the forces at work and a short history of monitor style barns I could certainly see his point
The " lean to" sides on a Monitor style barn were often added after the basic structure was built. The upper roof therefore was supported vertically to the ground with a wall and upright members. Those uprights also became the supports for the lower roof.
Here's a diagram to help explain what he was showing me.
Picture 3 people standing on two chairs back to back. The upper person is on a platform stretched between the backs of the two chairs . See the following diagram. The people represent the roof loads.
If you cut the back legs off both chairs, you create an extreme load at the point circled on the below diagram.
This was my area of concern. The diagonals that you have from the legs to the ceiling beam certainly help to transfer the load, and maybe that's enough.
The fact that you deal with very little snow load is also a factor I'm sure.
(you're right ))- I didnt look at your location, I just saw the snow in your pictures and assumed you were in a more Northern climate.)
The fact that there is no living area or other weight upstairs is also in your favor.Anyway, that's why I asked if the engineering had been done
The sockets or ferrules are a nice way to build , but they also have their limitations.
I certainly meant no disrepect in my previous post. I was passing along the information that was given to me by an engineer regarding monitor style buildings.
OK, I'm done now.
