Here are my specs so far for the shed I am getting made. I plan to use it as a shed for my very large tools.
It is 40 ft × 24 ft, with 11 ft high walls. It is made from galvanized steel while the walls and roof are something like this photo.
This is what I have done to help protect it from hurricanes and increase the survival chances.
-
I have made a strong concrete foundation that can handle 5 tons of tools and machines.
-
I plan to screw the galvanized steel to the foundation.
-
I plan to add shatter-proof windows and doors.

Studies have shown that certain home shapes and roof types can better resist high winds and hurricanes, according to new research. I can share a link if you want. In the research it says that a gable roof with a 30° slope would be a good idea.
What can I do to make it stronger and what have I missed?

In Florida, I have seen many sheds like the one in your picture further supported with cable or strap tie downs. Heavy galvanized eye bolts embedded in each side of the concrete slab. Then straps or cables attached to one eye bolt, up and over the roof and down to an eye bolt on the opposite side. Hope this helps, and hope you never need it. You can get anchors similar to the ones pictured below at many home stores. They can be installed and then the slab poured over them for added strength.
Then steel cable or web tie downs can be fastened to the anchors. The web tie downs come in up to 50 foot lengths and steel cables in any length. They can go over the roof or attached to other structural points depending on the design of the shed.
