After use, the air-supported structure can be taken down, decontaminated, and repackaged for shipment, storage, and reuse.
Air-supported structures could fill this need and have several advantages:
 At $15 per square foot for construction and erection, air-supported structures would cost approximately 80 percent less than conventional, permanent structures.
 Military-owned and -warehoused air-supported structures can be ordered and received in as little as 6 weeks.
This edition includes the application of new ground snow load tables for Colorado, Idaho, Montana, New Hampshire, New Mexico, Oregon, and Washington; new research from Norway and Japan on the probability of snow sliding off roofs; current concepts about how snow density changes over a winter season; snow loads on air-supported structures
; updated provisions for nonbuilding structures, including open-frame equipment structures, pipes, and cable trays; and calculation of snow loads on process piping.
We've tried domes and air-supported structures
, but they don't always make economic sense."
Many air-supported structures
feature a translucent white fabric, which allows natural day lighting to help illuminate the interior.
At the same time, 1978, a research department set up by Happold at the University of Bath, began to investigate properties and structural behaviour of lightweight and air-supported structures
. The research, together with experience in applying ideas to actual buildings, led to TENSYL, a computer program which analyzed the geometry of lightweight structures, developed load analysis and produced cutting patterns.
