Wind Loads on Thin Tubular Sections
Wind Loads on Thin Tubular Sections
(OP)
I am a civil/structural but am posting this on the ASME forum hoping it is something covered in the pressure vessel code.
I am looking for a reference on calculating local defromation of a thin tube due to wind loads. This is for determining the flatening or ovaling stresses. I have a reference for Krupka (in Czechoslovakian of course)and several formula but the results make little sense. I suspect it is an issue with conversion of units.
Smax = (1.566*q*R^2)/t^2) + (0.212*q*R)/t
Does anybody have a reference that give the correct units?
Does anyone have a refernce they can suggest?
I may be able to get my hands on a pressure vessel code in a few days if need be.
Thanks

I recently changed employers and have a copy of Roarks and a couple of other reference books are on order.
I will run an FEA but I always like to have something else to provide a GIGO check. This is one of those things that are difficult to do a reality check on.

See if the article below can give you some insights. The author also has some references at the end.
