Abstract:
Concrete domes in excess of 200 ft (61 m) in diameter have been built successfully using air forms. The domes have many uses ranging from houses to large auditoriums and commercial buildings. Storage of granular materials has proven very practical with some storing as much as 40,000 tons (36,290 Mg) of fertilizer or 1 million bushels of wheat. The use has extended to the storage of liquid materials. Water tanks have become practical and economical. Construction problems have included collapse of the air form, collapse of the concrete and steel, uplift of the footing, and excessive stretch of the forms. The problems have been overcome and expanded use of the air form continues. Domes up to 300 ft (91 m) in diameter are currently being considered.
