G.M.
I'm a Structural Engineer and I think you've done all you can do to protect your things. The Quonset shape is good and it appears that you have it anchored well. The worse thing that can happen in high winds is to loose doors or windows...the wind will pressurize the interior compounding the pressures the building is experiencing. That's one of the reasons roofs blow off. The most critical element of your building is the overhead door...all the wind loading is going to the two tracks and with a big door there's lots of load. It sounds like you've thought about all of this and have taken extra precautions. I'm crossing my fingers for you...please let us know how things turn out.
