Canadian Ammunition Storage Magazines
Abstract
Canada's ammunition storage magazines, designed by the departmental engineers, can rightfully qualify for the title "The World's largest igloos" given their unprecedented characteristics in terms of structural engineering features (reinforced concrete box structure with a clear span of 17m, depth 28m, and clear height of 5.7m) and storage capacity of 250,000 kg. of equivalent TNT of Hazard class/div 1.1. This paper describes the design criteria, design methodology, construction, costs, and various requirements of safety, security, and operation employed in these magazines. Currently, 17 igloos have been constructed and 11 others with reduced capacity but similar structural engineering features are being planned for construction in the summer of 1992. The siting of the battery of igloos is such that the static design required for the normal environmental loads is adequate to carry the large dynamic blast loads from accidental explosions without the undue premium usually paid to achieve blast resistant facilities. Special attention is drawn to the design controlled by the blast loads on the roof, and not on the head wall as seen in many short span igloos.
