Date of Defense 1998-11-19 Availability unrestricted AbstractA pressurized arch-shell structural component made of flexible material is considered.
The component is inflated with high internal pressure. The behavior of similar types
of structures, such as a pair of leaning pressurized arches and pressurized arch-supported
membrane shelters, has been investigated in the past. More recently, several types of
pressurized structures have been incorporated as part of the framework for a variety of
structural systems. Particularly, the U.S. Army has been investigating the use of large
lightweight and transportable pressurized arch-shell structures to be used as maintenance
shelters for vehicles, helicopters, and airplanes.
The formulated equations using thin shell theory are applied to a pressurized arch-shell
component. A numerical investigation based on the Rayleigh-Ritz method is utilized to
determine the behavior of arch-shells under various types of loading. The types of loading
include a uniformly distributed vertical load representing snow, a wind load, and a
horizontal side load distributed along the arc length. Deflections, stress resultants, and
moments at various locations are computed for two types of shapes: circular and non-circular
