Oh, you could tie it down easily enough.

Penetration and integrity would depend on actual construction and
materials, primarily door connections, etc.

I'm just not sure what their actually built from to judge absolute
survivability. As noted above, Texas A&M has good data/guidelines on
structure requirements and building techniques.

The effects _can_ be designed for, it just takes far more for the truly
extreme event than most folks can comprehend.
