Question 8

Air-Supported Structure

Answer 8

Membrane structure that is fully or partially held up by interior air pressure. This type of occupancy often has a wider footprint than air-inflated structures, and may be secured in place with rigid lower walls and cables. This type of structure may be maintained in place over a long duration.

Question 17

Smokeproof enclosures are now required for buildings with

Answer 17
