Abstract
Concrete thin-shell domes constructed using air-supported forms are increasingly built for a variety of uses. A number of these structures have experienced extreme natural events including hurricanes, earthquakes, and tornados. We provide evaluations of loads applied to these structures based on reported forces during the events, and analyze building performance. We compare this theoretical analysis to reports of building survivability from owners and users of the structures after event occurrence. We determine that in most cases the loads experienced do not approach minimum practical design loads, and identify special considerations for designers
