ABSTRACT:
An air supported structure includes a wall portion formed from a plurality of elongated panel members joined together by seams. Webs are interconnected along the seams to relieve stress. A plurality of header cables carry the loads placed on the structure. The header cables extend between corner support assemblies and a funicular cable assembly. The funicular cable assembly extends in an arcuate path around an apex of the structure. More specifically, the funicular cable assembly includes first and second independent strands. The webs passing through the apex of the structure are alternatively connected to these two cable strands. These same webs extend between and are connected to a ground anchoring structure at one end and a crown harness at the other that extends along the apex. The funicular cable assembly advantageously serves to balance the loads placed on the header cables by, for example, changes in wind speed and direction, so as to significantly enhance the stability of the structure.
