Good references for design of circular ducts with large D/t?
Good references for design of circular ducts with large D/t?
(OP)
I am designing large circular ductwork and am always looking for more good references, especially ones that address stiffening rings. There doesn't seem to be much new out there lately. Most references discuss the need for stiffeneing rings only when there is negative internal pressure. What about adding stiffening rings to increase buckling capacity and therefore increase span when bending moment is significant (with or without internal pressure)?
My main references have been Troitsky, SMACMA, AISC, AISI Plate Engineering Data Vol II, TM 5-809-6, ASME ST-1-2011, ASCE "Structural Design of Air and Gas Ducts for Power Stations and Industrial Boiler Applications" (this book tells you what to do but not really how to do it).
Does anyone know where I can get a copy of the two references below? These seem like they may have some useful information.
1. "Analysis of Circular Conveyor Galleries", H.M. Haydl (1980)
2. "Design Aspects of Large Diameter Tubular Conveyor Galleries", H.M. Haydl (1986)

I did a duct last year using FEA to get the plate stresses and ring spacing to determine allowable shell buckling stress.
