The Air-supported Membrane Roof at Dalhousie University, Halifax, Nova Scotia, Canada

The paper describes the design and construction of an 82 m × 64 m clear span roof, super elliptical in plan, composed of thin stainless steel sheet supported by internal air pressure. The patented Sinoski joint inserted between segments of the roof to permit construction on the flat is also described. Other aspects discussed are the reinforced concrete perimeter compression ring, the welding of the sheet and aeroelastic model wind tunnel testing.
