Thank you for the response JStephen! Moving the loading is not an option in this situation. I had a feeling that the allowable local buckling compressive stress was meant for designing shells subject to uniform loading from gravity and winds. But given that there is no specific sections under...
I am concerned about the localized out of plane loading into tank roofs from antenna wind loads (multiple 700-800 lbs. point loads). The tank roof doesn't have any rafters, stiffeners or supporting structure. The roof diameter is about 27' and plate thickness is 3/16". AWWA D100-21 is not very...
