physical education center seating 15,000 people in post-free space, has just been completed at Montana State College, Bozeman.
The Mahaffey Clear Span
tent is made from a durable aluminum frame with a wind and weather resistant vinyl covering, which can be custom made to any width between 10 and 50 meters, and up to any length and height, including a special "megastructure'" scale capable of accommodating up to 5,000 people.
The 20 units, arranged in three terraced blocks,are constructed of clear span
steel portal frame covered with insulated profile plas-tic coated steel cladding, incorporating block work walls.
Each factory has a steel portal frame with low pitched roof, giving a clear span
and height to eaves of 4.8metres.
The project would result in producing the thirdlargest "clear span
" tram in the world, and the longest.
Most of these steel buildings can accommodate up to 250-foot clear span
- a space large enough to fit a 747.

portal frame and 8.5 metre eave height.
One of the conspicuous reasons such domes make outstanding sport facilities is their clear span
. Because of the inherent strength provided by its shape and construction, the structure does not have to be supported by columns that take up space and block sight lines.
