Upper limit to size of Air Supported Structure?? Hey yall! Im new here, and I'd like to ask a question I can't seem to get an answer to anywhere else, so why not get it here! I'll get right to it! The question is...What is the upper limit of an air supported structure, and what is the maximum safe pressure inside said structure? Can they simply be made as large as you would like? Or is there limits such as outside wind force, inside pressure of structure relative to overall weight of the structure, the structure tearing from the immense forces created by rising air, shape of structure, volume of air within structure ect. please list the equations or whatever else involved in your reasoning, thanks!
